TestoJack 100™ – Bioavailability Study
Bioavailability Study
TestoJack 100™ features standardized extract of Tongkat Ali (or Long Jack) that may support male reproductive function, as well as Tribulus with its virility supporting effects and ZMA® for the support of healthy immune, reproductive and neuromuscular function.* A healthy 42-year old male volunteer took 2 capsules of TestoJack 100™, a dietary supplement by NOW® (item # 2168), twice a day for 4 weeks without dietary and lifestyle modifications. Total and free testosterone was measured at the baseline, and after 4 weeks of supplementation.
Results
At the end of the observation period, total and free testosterone increased by 25% above the baseline level. The case study indicates that supplementation with TestoJack 100™ in this healthy adult male was effective in supporting testosterone levels already within normal range.* Interpretation of the results is limited due to the observational nature of the case study.
