TestoJack N O - 90 Veg Caps

NOW Foods TestoJack N.O. combines two heavyweight ingredients for men's health: L-Arginine and Tongkat Ali (Eurycoma longifolia).

By pairing a direct vascular vasodilator with a traditional herbal aphrodisiac and testosterone regulator, the formula targets male vitality from two complementary angles: blood circulation (mechanics) and hormonal drive (motivation).

1. L-Arginine: Nitric Oxide & Vascular Performance

• Enhanced Blood Flow & Sexual Performance: When L-Arginine is absorbed, endothelial cells produce nitric oxide. This relaxes smooth muscle tissue in blood vessels (vasodilation), improving blood delivery to pelvic tissues during arousal.
• Muscular Pump & Exercise Stamina: Systemic nitric oxide production delivers oxygen and nutrients to active muscle tissues more efficiently, reducing exercise fatigue and supporting muscle recovery.
• Cardiovascular Support: By keeping arterial walls flexible, nitric oxide promotes healthy resting blood pressure and overall vascular tone.

2. Tongkat Ali: Testosterone & Hormonal Vitality

• Free Testosterone Optimization: Tongkat Ali helps free up bound testosterone by lowering Sex Hormone-Binding Globulin (SHBG), making a higher percentage of active testosterone available for muscle retention, energy, and drive.
• Libido & Sexual Appetite: Clinical studies demonstrate that standardized Tongkat Ali extract improves sexual desire, subjective satisfaction, and overall male reproductive function.
• Stress & Cortisol Balance: Tongkat Ali helps regulate the stress response by reducing circulating cortisol levels, protecting testosterone production from stress-induced dips.
