The potent formula features a science-backed key ingredient in a fully disclosed, clinically-dosed amount. In a 12-week human scientific study, hard-training subjects gained 8.8lbs. of lean muscle vs. the placebo group, which gained 4.6lbs. That's 90% more lean muscle. In another part of the same study, tests subjects increase muscle thickness by 96% more than the increase for the placebo group. These same subjects experienced an increase in strength that was 147% more than the strength increase achieved by the placebo group.
