N1-T. Natural Testosterone Formula. Advanced Test-Sim Complex. Maximum Absorption. Patented LJ-100. Natural test complex. N1-T: Natural Testosterone Formula. N1-T is a complete and potent pro-testosterone formula that harnesses the power of three special extracts of tribulus (protodioscin), patented longjack (Eurypeptides), and avena (avenacosides A and B). The ingredients in N1-T have been shown in actual human clinical trials to nearly double testosterone, increase free testosterone, decrease SHBG (sex hormone binding globulin), increase IGF-1, and modulate cortisol levels. With an increase in total and free testosterone, you can expect more from your body and from your training. So the next time you're looking to add gains, train hard and look to N1-T. 100% Guarantee: All Universal Nutrition products are formulated with the highest quality ingredients available under the strictest controls in our own state-of-the-art facilities.
