A multi-ingredient male vitality blend from NOW, combining botanicals like Tongkat Ali, Maca, and Ginseng for energy and libido, but with limited scientific backing for direct testosterone boosting and muscle gain from its Tribulus component.
NOW TestoJack 200 (120ct) is formulated with a multi-herb blend including Tongkat Ali, Maca, Epimedium, Ginseng, and Tribulus terrestris. This combination aims to support male vitality, energy, and libido. Ingredients like Ginseng and Maca are recognized for their adaptogenic and energy-boosting properties, while Tongkat Ali shows some potential for modest testosterone support in specific populations (e.g., those with low levels or under stress) and improved libido. However, the inclusion of Tribulus terrestris, often marketed as a potent testosterone booster, is a point of contention as scientific research generally finds limited direct impact on endogenous testosterone levels or muscle gain in healthy individuals. The high volume of positive online reviews often reflects perceived benefits related to energy and general well-being rather than significant hormonal changes or an anabolic effect.
