Why Choosing 7-Keto DHEA Over Standard DHEA
February 25, 2012 06:36 AM
The Importance OF DHEA Nowadays
DHEA (Dehydroepiandrosterone) is probably one of the most abundant hormone that can be found in the human blood. Being produced in the adrenal cortex, this important steroid it's very important in reducing body fat, cholesterol and also the alleviate angina. In addition to all that, DHEA has been widely used to treat coronary artery disease, Alzheimer's, sclerosis, depression, osteoporosis and even cancer. Because of this, DHEA is known under the name of “Fountain of youth.”
DHEA levels will usually decrease with age. This decrease might lead to high cholesterol levels, cardiovascular disease, neurodegeneration and even obesity in many cases. These are only a few reasons that make of DHEA an imperative hormone for our body.
What Makes 7-Keto DHEA Better Than Standard DHEA?
7-Keto Dhea it's similar to its cousin hormone, however it is much better for your body. Some of its extra benefits that can't be find in the standard DHEA are:
- Enhances your immune system.
- Improves your memory.
- Increases your muscular mass and strength.
- Help you lose fat naturally.
- Increases the activity of your thyroid gland.
- Reduces the signs of aging.
Overall, 7-Keto DHEA is a safer and a more potent derivates of standard DHEA, proved to be safer and with less side effects. 7-Keto DHEA is a real breakthrough as it represents the next generation of DHEA supplements. How was this discovered?
In the previous years, the University of Wisconsin conducted an extensive research in order to discover the best DHEA derivates. Over more than 150 DHEA derivates analyzed, a single compound stood out- it was 7-Keto DHEA. This compound provided greater benefits over a long-term period than the standard DHEA. Nowadays it is considered an improved and much safer form of this important hormone, called DHEA.
In addition to providing all therapeutic benefits of DHEA, this improved hormone won't be converted into some unwanted sex steroids. It also lacks any other hormone- elevation that was commonly found in the standard DHEA supplements. This product makes you feel young again without endangering your body tissues or internal organs, compared to the traditional DHEA whose side effects were found destructive to some of your body tissues.
Why To Take This Hormone?
7-Keto Dhea was proven to be a safe product in a clinical trial, being tested on many people and animals. The only side effects this hormone might have are some mild heart palpitations and sometimes acne. Still, these side effects won't usually appear on people who take this product as prescribed and also avoid taking an overdose.
The benefits this hormone provides to our body are very real, as they were discovered at those who took this hormone for a longer period of time. Enhancing your immune system, the response to viruses is stronger. You will feel healthier and better protected.
When Should You Take It?
This hormone is to be taken only after you reached 30 years old, as you won't need it before that age. DHEA hormone begins to decrease considerably only after you reach 30, so this process will continue until you reach 70 or 80 years old. Taking the 7-Keto Dhea hormone will help you feel and be younger.

The whole human body is made up of cells that contain their own genetic material. In a healthy body, these cells divide at a controlled rate, growing and repairing damaged tissues and replacing dying cells. This predetermined rate of cell division is what keeps our bodies healthy. If cells keep multiplying when new ones are not necessary, a mass of tissue, often known as a tumor, is formed. This tumor can be either benign or malignant.
Benign tumors are not cancerous and can occur anywhere in the body. Benign tumors do not cause a threat to health, do not metastasize, and do not grow back if removed. Malignant tumors are cancerous and are usually serious. Often times, they can be life-threatening. Malignant tumors grow uncontrollably, interfere with normal metabolic and organ functioning, and have the ability to metastasize and invade other tissues. If a portion of a cell’s DNA is damaged, the cell can become abnormal. When an abnormal cell divides, it forms new cells that are a photocopy of the damaged genetic material. This ongoing process occurs constantly within our bodies. The majority of the time our bodies have the ability to destroy these abnormal cells and maintain a sort of cellular equilibrium. If a crucial part of the DNA is destroyed and the abnormal cells cannot be controlled any longer, cancer forms. All cancer cells have two things in common: growing uncontrollably and having the ability to metastasize. The immune system does not recognize cancer cells as dangerous or foreign.
Although the exact cause for the cell damage that initiates the cancer process is unknown (theoretically free radical damage causes DNA damage), the chain of events that leads to cancer is very complex, and each individual body reacts differently. It is a combination of genetic, behavioral, environmental, and lifestyle factors that are thought to be involved in turning normal cells into abnormal cells, and abnormal cells into cancer.
There are also factors that are believed to slow the process, while other factors can speed up the process. Possible contributors to the development and growth of cancer can be divided into three categories: external, internal, and lifestyle. External factors include unhealthy workplace environments and exposure to air and water pollution, chemicals, pesticides, and herbicides. Included in the internal factors include both genetics and infections. Lifestyle factors are those we personally can most readily control, such as diet, smoking, drinking, and sun exposure. External and lifestyle factors account for 80 percent of cancer deaths in the United States.
Just as each of us looks different, each of our bodies has its own unique composition. Some of us may react adversely to what some of us react well to. This is why some treatments prove to be successful for some, but not for others. This is why dietary wellness and prevention is so important. If we can keep our bodies healthy and avoid known cancer-causing agents, we have a good defense against cancer in the first place.

Infertility is typically defined as a failure to conceive after a year or more of regular intimate activity during the time of ovulation. This term can also refer to the inability to carry a pregnancy to term. About 6.1 million American couples are impaired when it comes to their ability to have children, with 2.1 million of these couples being infertile. The exact cause of the problem can be extremely difficult to pinpoint, as ovulation, fertilization, and the passage to the fertilized ovum through the fallopian tube and to the uterus are extremely complex processes. In order for pregnancy to occur, many events must work together perfectly.
In 40 percent of infertile couples, problems that affect the male partner are either partially or wholly the cause of infertility. Infertility in men is usually the result of a low sperm count or an anatomical abnormality. There are a variety of factors that can result in a low sperm count. Among these factors are alcohol consumption, endocrine disorders, exposure to toxins, radiation or excessive heat, recent acute illness or prolonged fever, testicular injury, and rarely, mumps-induced wasting of the testicles. An abnormal enlargement of veins that drain the testicles, referred to as varicoceles, can cause infertility in men. This is because the veins of the testes are no longer able to moderate the temperature of the testicles correctly, which can negatively affect sperm.
The most common causes of infertility in women include an ovulatory failure or defect, blocked fallopian tubes, endometriosis, and uterine fibroids. Additionally, some women are able to develop antibodies to their partners’ sperm, which causes the woman to almost be allergic to them. Chlamydia, a transmitted disease which affects 4 million Americans each year, also causes many cases of infertility. There are also psychological issues, such as stress or fear of parenthood, which can also contribute to infertility.
However, in most cases, stress is usually the result of infertility, not the cause of it. Sperm abnormalities account for about 41 percent of infertility cases. The following reasons are the most common to explain why couples cannot conceive: the woman has endometriosis; the man has abnormal sperm, a low sperm count, or erectile dysfunction; the woman’s fallopian tubes are blocked; ovulation takes place rarely or irregularly; the couple is unable to have complete intimate relations; the cervical mucous attacks and kills the sperm; the woman does not manufacture enough progesterone to carry a baby to term; the woman is over thirty-four; and/or one or both members of the couple eats a poor diet and experiences too much stress. The following nutrients are extremely beneficial in helping one or both partners deal with infertility: selenium, vitamin C with bioflavonoids, vitamin E, zinc, DMG, octacosanol, phosphatidyl choline, essential fatty acids, l-arginine, manganese, proteolytic enzymes, pycnogenol, raw orchic glandular, raw ovarian glandular, 7-Keto DHEA, vitamin A, and vitamin B complex. Also, the following herbs have been shown to be beneficial in dealing with infertility: astragalus, damiana, ginseng, sarsaparilla, saw palmetto, yohimbe, dong quai, false unicorn root, gotu kola, licorice root, wild yam root, green oat, and yin-yang-huo. It should also be noted that heavy use of Echinacea, ginkgo biloba, and St. John’s wort may cause infertility in men, and should be avoided.
Infertility can be a complicated and mentally depressing due to lack of pregnancy by both men and women. Depression can lead to more stress and needs managed by a health care provider. Always consult your doctor when you think you are infertile. Natural vitamins like the ones listed above are available at your local or internet health food store. Look for name brands vitamins to ensure you receive quality supplements.

7-Keto, The Next Dhea With No Side Effects
November 10, 2007 12:24 PM
7-Keto is a natural derivative of DHEA that is claimed to be free from many of the side-effects of regular DHEA supplements. DHEA is dehydroepiandosterone, which is the most abundantly produced of the adrenal hormones. After production in and release into the bloodstream by the adrenal glands that are situated just over the kidneys, DHEA undergoes metabolism to the male androgen hormones, and the female estrogens.
As you age, the production DHEA declines, starting at about 30, with a 50% decline by time you reach 40 and almost 85% at 70. This is true of the levels of many hormones in the body, though some, like the steroidal aldosterone, remain constant throughout life. The general rate of metabolism also reduces with age resulting in an even lower conversion rate of DHEA to the male and female hormones.
At the same time as this occurs, there also occurs a significant reduction in the biosynthesis of protein in the body, which results in a loss of muscle mass as you age, and also in the regeneration of bone tissue that results in what is commonly termed age-related osteoporosis. Brain cells die at an increasing rate leading to many neurological conditions and the immune system is also affected negatively.
Due to the concurrence of these aging effects, many scientists have related the general hormonal decline with the other effects of aging. The have asserted that if these hormones were restored, than many of the effects of aging could be delayed. Osteoporosis would be delayed due to the body’ s increased ability to restore lost bone mass, the metabolic rate would improve and fat would be burned at a faster rate and continue to build muscle, the brain would lose its functionality at a significantly lower rate and the immune system would continue to protect the body against disease.
In other words we might be able to live longer, but if not that then at least the quality of life would be maintained longer as we aged. This is a very welcome and desirable situation, but the taking of hormones as supplements has long been regarded as fraught with danger due to the possibility of undesirable side effects, some of them potentially very serious. DHEA was considered as one of these hormones that could be used as a supplement to achieve positive results in reducing these age-related changes because it exhibited these effects in tests on animals.
However, in order that a specific substance can be declared responsible for any metabolic improvement that involves liver biochemistry, some form of receptor has to be identified, and this failed to materialize in DHEA. There appears to be no such DHEA receptor, although that does not necessarily imply that DHEA is not responsible in some way. It might very well be a DHEA metabolite that is responsible, and that has still to be identified. It is certainly true that DHEA administered to both animal and human subjects has resulted in an increase in the testosterone and estrogen levels of the subjects. Such an increase is not desirable due to a number of potential side effects as previously inferred.
These are particularly liable to occur with people who already have an adequate level of natural DHEA production within their body. The side effects include acne, irregularity in the menstrual cycle, itchy scalp, increased body odor and an excess of androgenic hormones can lead to hair loss, or male pattern baldness. Interruptions in the heart rhythm, or palpitations, are another very serious side effect of DHEA supplementation, and high doses over a long period introduce a theoretical risk of certain cancers.
However, the discovery of 7-Keto, a natural derivative of DHEA claimed to be free from many of these side effects, has altered the situation. 7-Keto is a powerful antioxidant that speeds up the metabolism of fat and helps to reduce body weight. It also helps to replace lost fat with muscle mass, though it must be stated that this effect is only valid after the natural production of DHEA has slowed down. It is not a body-building supplement.
It was Professor Henry Lardy, of the Department of Biochemistry at the University of Wisconsin, who tested over 150 DHEA metabolites over 10 years and identified 7-oxo-dehydroepiandrosterone as having the greatest biochemical effect without having any detectable side effects. This material was trademarked 7-Keto by the Humanetics Corporation, and one of its known effects is to burn fat quicker by stimulating thermogenesis. It had also been shown to strengthen the immune system and to improve the memory. All of this without any measurable increase in any of the sex hormones. It was released after a careful and intensive series of safety tests on both humans and animals found it safe for human consumption.
It should be stressed that 7-Keto is not a hormone, and is not chemically the same as DHEA: it is a different chemical altogether that is produce when DHEA degrades in the body. Because of this it can be promoted as a non-androgenic or estrogenic form of DHEA. It is thought that all of the conditions that decline as we age that can benefit from a supplement of DHEA, will also benefit from a supplement of 7-Keto. However supplementation is only required from the ages of 25 – 30, when the natural amount of DHEA and 7-Keto in the body start to decline.
It causes neither high blood pressure nor any form of cancer, and was submitted to the FDA prior to being made publicly available. It is important to stress that the substance is neither a steroid nor does it metabolize to steroidal hormones, and is also not a sex hormone. It also has no effect on the body’s sex hormones. The whole point of 7-Keto is that it has the effect of DHEA without having any connection whatsoever with steroidal hormones or any hormonal substances. It is totally innocuous and safe to use, without the risk of heart palpitations, lost hair or any of the other side effects of DHEA.
Without a doubt, 7-Keto is a DHEA substitute that has none of the side effects of its precursor. So if you are over the age of 30 and feel the need for an energy boost, give 7-Keto a try.
7-Keto - Anti-Aging and Antioxidant Protection

“Anti-Aging and Antioxidant Protection”
The Fountain of Youth Discovered in Wisconsin
It turns out that Ponce de Leon was looking in the wrong place for the fabled Fountain of Youth. It was recently discovered – in Wisconsin! And it turns out that the Fountain of Youth isn’t really a fountain – it’s a biological compound produced in our own bodies. This compound is extremely important for the growth and development of the human body, and, as the body’s production of this substance decreases with age, the signs of aging begin to appear – weight gain, wrinkled skin, loss of muscle, loss of cognitive function, and loss of libido.
This biological Fountain of Youth was discovered by Dr. Henry Lardy and associates at the Institute for Enzyme Research at the University of Wisconsin. It’s called 7-Keto™, a metabolite of a hormone produced by the adrenal glands called DHEA (dehydroepiandrosterone). Research on 7-Keto™ indicates that it may work through a number of pathways to combat the signs of aging. Helping the body maintain a healthy weight as we age greatly improves overall health and longevity and is one of the strongest benefits discovered for 7-Keto™ to date.
Unfortunately, because 7-Keto™ is a metabolite of DHEA, whose levels decline as we age, so to does this wonderful, natural bio-nutrient. Scientists originally looked to DHEA for improved cardiovascular vitality, and strengthened immune and brain function3. Researchers believed that declining DHEA so profoundly impacted our bodies that it could be partly responsible for the effects of aging. They hypothesized that supplementation with DHEA could sustain hormone levels and stave off many of the degenerative changes we collectively call aging. But there was a catch. Because DHEA is converted into sex hormones, people taking supplemental DHEA would sometimes experience the frightening, unwanted side effects associated with hormone supplementation.
In 1989, Dr. Lardy and his colleagues set out to solve the mystery of eliminating DHEA’s side effects by examining all of the constituents that make up DHEA. Ten long years of research unearthed hundreds of DHEA derivatives, which were developed and tested continuously, until one derivative rose above all the others – a metabolite that was incredibly bio-active and far more promising than any other substance they’d tested. That metabolite is 7-Keto™. 7-Keto™ outperformed DHEA and other metabolites in immune modulation, memory enhancement and thermogenesis and, more importantly, without any adverse side effects3.
The most significant benefit of 7-Keto™ supplementation is its ability to support healthy body weight. Obesity is a major contributing factor in a number of serious medical conditions. A recent study assessed the effectiveness of 7-Keto™ on weight loss and body fat loss. Participants were divided into two groups; one group received 100mg of 7-Keto™ twice daily and the other a placebo. Both groups exercised three times per week. At the end of the study, researchers noted a statistically significant reduction in body weight and body fat only in the 7-Keto™ group. Researchers concluded that 7-Keto™ was three times more effective than diet and exercise alone in promoting weight and fat loss1,2,7. Preliminary research also indicates that 7-Keto™ may support healthy immune and nervous systems. One study measured the effects of 7-Keto™ on memory function. Subjects were given a single dose of a substance that inhibits nerve cell communication and causes shortterm memory loss. Afterwards subjects were given a single dose of 7-Keto™. Results showed that 7-Keto completely reversed the memory impairment, suggesting that 7-Keto™ supports memory retention6.
Another study gauged 7-Keto™’s ability to support immune system function. Interleukin 2 (IL2) is a substance produced by T lymphocytes that causes an increase of disease fighting white blood cells. White blood cells were taken from healthy volunteers and introduced into a solution that contained 7-Keto™ for 24 hours. When the cultures were tested for heightened IL2 production. 7-Keto™ was shown to augment IL2 production by a statistically significant 68%4.
NOW® 7-Keto™ is a well-researched and patented form of this amazing product that’s supplied by the Humanetics Corporation. Humanetics 7-Keto™ has been proven safe and well-tolerated in doses up to 200mg5. Research is clear, the rate at which we age can be influenced by the diet and lifestyle choices we make. One very smart choice would clearly be adding NOW 7-Keto™ to your diet.

7-Keto - The Key to Healthy Aging
June 21, 2005 05:05 PM
The global population is aging at an alarming rate and causing an explosion in health care costs, insurance premiums, cosmetic surgery and more. In the U.S. alone, more than one million baby boomers are expected to live to 100 years of age or older. This increased life expectancy presents a whole new set of health concerns that the medical community has not had time to address, since there is a greater need to care for age-related health problems in this ever-growing elderly population.1
Aging and the Decline in Vital Nutrients
We all grow old at the same rate but people age at different rates. Aging is a process of gradual changes that occur to varying degrees in each of us. Interestingly, the aging process is composed of different components and interactions, some of which can be impacted. One such component is the declining level of essential biological compounds, which causes our bodily functions to slow and become dysfunctional. Our organs don?t work efficiently, our immune system becomes lazy, we lack energy, our metabolism drops and we gain weight easily.1 7-oxo DHEA (7-Keto™) is a naturally occurring compound that declines with age.2 Replacing this key metabolite helps promote a healthy immune system and maintains resting metabolic rate at levels that accelerate weight loss during standard weight reduction programs.
Aging and a Healthy Immune System
Numerous changes occur in the immune system with advancing age, probably contributing to decreased immune responsiveness. Although all segments of the immune system are affected, investigators have most consistently identified declines in cellular or T-cell mediated immune function in the elderly. The decline in T-cell immune function is generally associated with an increased susceptibility to foreign organisms. For example, individuals with age-related declines in cellular immunity have an impaired response to vaccinations, making them more susceptible to health imbalances even though they have had their shots. In a clinical study presented at the Federation of American Societies for Experimental Biology meeting in April 2004, the effect of 7-Keto on elderly immune function was evaluated. Healthy elderly adults were given 7-Keto orally twice daily over a period of one month. The study revealed that 7-Keto augmented several key T-cell mediated immune function parameters compared to placebo administration.4
Age-Related Weight Gain
Age-related weight gain and obesity are approaching epidemic proportions in our country.5 Weight gain is a disorder of energy balance involving energy intake and/or expenditure. Low energy expenditure, a drop in resting metabolic rate (RMR), is a challenge during most weight loss attempts due to age, calorie restriction, lack of physical activity or a combination of factors. RMR represents 60% of total daily energy expenditure. Maintaining a higher RMR as we age and during weight reduction programs helps us achieve and maintain a normal weight. Furthermore, compounds with the thermogenic potential to achieve even minimal increases in daily energy expenditure of 2-3% may have clinical relevance in preventing the decline in RMR with calorie restricted diets or weight loss, and in decreasing the risk of regaining weight. 7-Keto, a non-stimulant thermogenic compound, has been shown to significantly increase energy expenditure in humans.6 A recently completed clinical study, also presented at the Federation of American Societies for Experimental Biology 2004 meeting, revealed that administration of 7-Keto to overweight adults in conjunction with a calorie restricted diet effectively reversed the decline in RMR normally associated with dieting. Obese participants following a calorie-restricted diet demonstrated a 5.4% increase in daily RMR with 7-Keto.7 The magnitude of the increase in RMR by 7-Keto is clinically relevant, and represents a promising agent for enhancing thermogenesis and weight loss in obese individuals on calorie-restricted diets. Additionally, 7-Keto has been shown in two confirmatory published clinical studies to result in three times more weight loss compared to diet and exercise alone. It has a favorable side effect profile and is easy and convenient to take.8,9 Our life expectancies will likely be longer than those of our parents, and our quality of life during those years will depend on how well we take care of our bodies now. Undoubtedly, the science of aging will give rise to new and exciting technologies to help us age more gracefully and healthfully. Maintenance of healthy immune function is keenly needed for improved quality of life in the elderly. Dietary manipulation and supplementation has been identified as a method of immune system renewal, and supplements such as 7-Keto may play an important future role as immune system modulators. Moreover, the addition of 7-Keto to any weight loss program will offer vital support of energy expenditure and help with the attainment of a manageable and healthy weight into our older years.

Dietary glucarate as anti-promoter of 7,12-dimethylbenz[a]anthracene-induced mammary tumorigenesis. Walaszek Z; Hanausek-Walaszek M; Minton J P; Webb T E Carcinogenesis (1986 Sep), 7(9), 1463-6. Journal code: 8008055. ISSN:0143-3334. United States. Journal; Article; (JOURNAL ARTICLE) written in English. PubMed ID 3091283 AN 86298867 MEDLINE
Using as a criterion the inhibition of serum beta-glucuronidase activity, dietary calcium D-glucarate is shown to serve as an efficient slow-release source in vivo of D-glucaro-1,4-lactone, the potent endogenous inhibitor of this enzyme. Using the 7,12-dimethylbenz[a]anthracene model of mammary tumor induction in rats it is shown for the first time that feeding the rats calcium D-glucarate-supplemented diet after treatment with the carcinogen, inhibits tumor development by over 70%. Supportive evidence is presented for the theory that calcium D-glucarate inhibits or delays the promotion phase of mammary carcinogenesis by lowering endogenous levels of estradiol(estrogen) and precursors of 17-Ketosteroids. Therefore, dietary glucarate can be used to lower blood and tissue levels of beta-glucuronidase, and in turn of those carcinogens and promoting agents which are excreted, at least in part, as glucuronide conjugates.

Bee Propolis may limit production of DHT...
May 17, 2005 05:00 PM
Chrysin controls aromatase activity, and thus the production of estradiol and estrone, and provides an alternative embodiment of this invention. This embodiment may further comprise a substance that controls 5-alpha-reductase and its production of DHT.
Other aromatase inhibitors include substituted androstenediones. There is also evidence that aromatase is involved in the production of DHT, which is well known for its negative effects on the prostate and male pattern baldness. An in vitro rat testis cell suspension model was used to investigate the metabolism of tritiated testosterone, dihydrotestosterone, and androstenedione. In the presence of aromatase inhibitors and androstenedione, the metabolism was shifted towards 17-Keto forms. This suggests that androstenedione and the derived aromatase inhibitors activate the 17 .beta.-hydroxysteroid-dehydrogenase in a product-activating manner. Thus, aromatase inhibitors may regulate the intratissular levels, not only of estrogens, but also of other hormonally active steroids like DHT and 5-androstenedione. Schroder et al., 31(4B) J.

Because of the usefulness of inhibiting aromatase in breast cancer patients, several synthetic aromatase inhibitors have been developed. See, e.g., U.S. Pat. No. 4,954,446. There are natural substances, however, such as chrysin, that have similar activity. Chrysin is a bioflavonoid found in propolis (bee pollen) and honey that has been demonstrated to be as potent and effective in inhibiting aromatase as the popular pharmaceutical, aminoglutethimide (AG). In aromatase enzyme assays, chrysin, 7,8 benzo-flavone (ANG), AG, flavone and genistein 4'-methyl ether (5,7-dihydroxy-4'-methoxyisoflavone, Biochanin A) were shown to inhibit aromatase. Chrysin and AG inhibited the enzyme by 50% at a concentration of 4.6 .mu.M and 7.4 .mu.M, respectfully, and only ANG had a high I.sub.50 of 0.5 .mu.M. Both Flavone and Biochanin A inhibited aromatase, but to a lesser degree. Campbell et al., 46(3) J. STEROID BIOCHEM. MOL. BIO. 381-88 (1993). In screening for potential chemopreventives against cancer, chrysin was one of the three of flavonoids with the greatest aromatase-inhibiting activity, with an inhibitory concentration (IC) of 1.1 .mu.g/mL.

Androgens and 4-Diol and 4-Dione conversion to Testosterone...

The androgens 4-androstenediol and 4-androstenedione are natural testosterone precursors. The biosynthesis of testosterone takes place within the testicular Leydig cells in two metabolic pathways. During the progesterone-pathway (.delta.-4 pathway), pregnenolone is metabolized to progesterone by the 3-.beta.-hydroxy-steroid deydrogenase and an isomerase. Progesterone is then changed to 17-.alpha.-hydroxyprogesterone by the 17-.alpha.-hydroxylase and C.sub.17C.sub.21-lyase to androstenedione, then to testosterone by reduction of the 17-Keto-group by 17-.beta.-hydroxy-steroid dehydrogenase. The DHEA-pathway (.delta.-5 pathway) leads from pregenolone to 17-.alpha.-hydroxypregnenolone to dehyroepiandrosterone (C.sub.17C.sub.21-lyase), to 5-.delta.-androstenediol. See FIG. 4; Wichmann et al., 83(3) EXP. CLIN. ENDOCRINOL. 283-290 (1984).
As a testosterone pro-hormone and metabolite, 4-androstenedione may be used by athletes and bodybuilders to improve muscle mass. Levels of .delta. 4-androstenedione increase significantly with moderate exercise in healthy men. Velardo et al., 97(1) EXP. & CLIN. ENDOCRINOL. 99-101 (1991). Additionally, supplementation with 4-androstenedione has been known to produced elevations in serum testosterone. Mahesh et al., 41(3-8) J. STEROID BIOCHEM. MOL. BIOL. 495-513 (1992).
4-androstenediol is also metabolized into testosterone and is produced by conversion of dehyroepiandrosterone. Inaba et al., 13(2) ENDOCRINOLOGIA JAPONICA 160-72 (1966). It was first shown to produce elevations in human serum testosterone levels in 1965, and this was also demonstrated in in vitro studies in animals (Kundu, 6(5) STEROIDS 543-51 (1965) and human fibroblast cultures. Faredin et al. 32(2) ACTA MEDICA ACADEMIAE SCIENTIARUM HUNGARICAE 139-52 (1975). Supplementation with 4-androstenedione, 4-androstenediol, and 19-nor-4-androstenedione has been studied to determine whether a rise in testosterone is produced. Uralets et al., 23 ANAL. TOXICOL. 357-366 (1999). Testosterone is excreted in the urine unchanged and is metablized through 5.alpha.- and .beta.-DHT as 5.alpha.- and .beta.-androstanediol, while androstenedione is similarly excreted as androsterone and etiocholanolone. Both the final excreted steroid and the intermediaries stanediones and DHT intraconvert so that androsterone, 5.alpha.- and .beta.-androstanediol and etiocholanolone are seen in urine. Supplementation with 4-androstenediol produced a 10-fold greater urine testosterone concentration than 4androstenedione. (Uralets, 1999)

Composition and method for increasing testosterone levels
Abstract This invention provides compositions and methods related to the administration of deer antler, one or more nor-testosterone precursors, and one or more testosterone precursors, to increase testosterone levels, treat sexual dysfunction, improve sexual function, improve energy, enhance feelings of well-being and increase muscle mass in males. This invention also provides for inhibitors of the enzymes aromatase and/or 5-alpha reductase, to support testosterone levels and avoid undesirable metabolites.
May reduce DHT:
By using velvet deer antler along with the testosterone and nor-testosterone precursors, the antler promotes youth film testosterone levels while balancing and ameliorating dangerous spikes in these levels. Another embodiment of the invention includes herbs that inhibits 5-alpha-reductase reducing undesirable levels of dihyrotestosterone. Another embodiment includes chrysin, which inhibits aromatase and the production of estrogenic steroids.
Deer antler (called Rokujo in Ancient Chinese Medicine) is used for its sexual-reinforcing and anti-aging actions. Wang et al., 36(7) CHEM. PHARM. BULL. 2587-92 (1988). Velvet antler is living tissue that grows at a rate of up to 2 cm/day in some species. Cartilage, bone and support tissues such as nerves, blood vessels and hair follicles of the antler also evidence accelerated growth. Antler is the only mammalian organ that regenerates. These features, responsible for the accelerate growth of velvet antler are likely to be caused by either unique regulatory substances or substances found in other tissues but at lower levels. It is believed that factors actually responsible for the rapid regeneration of the velvet antler can explain the powerful health benefits of the product. Specifically, velvet deer antler regulates the adrenal cortex and energy metabolism, promotes sexual function and growth, and strengthens resistance. Its functions fall into the major categories of general body strengthening, healing, promoting blood cell growth and improving immune and cardiovascular function.
Some of velvet deer antler's key ingredients include lysophosphatidyl choline, with hypotensive activity, phosphatidyl ethanolamines, sphingomyelin, phosphatidyl choline hypothanthene and uridene, with monoamine oxidase (MAO)-inhibiting and anti-aging effects; polyamines spermine, spermidine and putrescine, with RNA polymerase stimulating effects; gangliosides that may promote memory and learning; and anti-inflammatory amino acids. A wide variety of growth factors are also found in velvet, and may be associated with its growth-promoting activity. Tsujibo et al., 35(2) CHEM. PHARM. BULL. 654-59 (1987).
As taught by ancient Chinese medicine, deer antler tonifies the yang, primarily deficient yang of the kidneys, spleen and heart. Because kidneys are the seat of the basal yang, the most important use of this class of herbs is to tonify the kidney yang, whose principal manifestation of deficiency is systemic exhaustion. Yang deficiency causes impotence, spermatorrhea, watery vaginal discharge, infertility, enuresis, polyuria, wheezing and daybreak diarrhea. Patients with deficient kidney yang very often have decreased plasma thyroid hormone binding proteins, 24-hour urinary 17-Ketosteroids, and decreased rate of glycolysis. When treated with tonifiers such as deer antler, these measurements return to normal ranges. BENSKY ET AL., CHINESE HERBAL MEDICINE, MATERIA MEDICA, REVISED EDITION Eastland Press, Seattle, Wash.
