- An 8-week, randomized, double-blind, placebo-controlled study of 33 healthy men compared the effectiveness of this proprietary module of whey protein and leucine vs. an isocaloric carbohydrate placebo consumed before and after resistance training. Subjects consuming the leucine-whey protein supplement experienced greater increases in muscle strength than those on the placebo. Leucine-whey protein supplementation also increased muscle cross-sectional area from baseline.
