†When used in conjunction with whey protein isolate and an exercise program. As with any food product, use of this product alone will not lead to increased muscle mass or strength.
◊Product was tested for over 145 banned substances on the 2013 World Anti-Doping Agency (WADA) Prohibited List via HFL skip lot testing protocol #ICP0307.
^When stacked with a product containing whey protein isolate (WPI) in a randomized, double-blind, cross-over clinical trial with 20 recreationally trained, healthy male subjects, those taking 10 grams WPI and 10 grams leucine immediately post-workout showed significant increases in plasma insulin concentration. Those taking the WPI and leucine blend showed 4 times more insulin in 30 minutes post-workout compared to a placebo.
°An 8-week study of athletes performing an intense resistance exercise training regimen demonstrating that those using the proprietary module of whey protein leucine had greater increases in muscle strength and size than those on a placebo.
*Specifically designed to stack with products that do not already contain creatine.
