UPA Anabolicum LGD-4033

Healthy men who took LGD-4033 for 21 days saw a significant increase in lean body mass. The only side effect was short-term testosterone suppression (more on that in a second) [3]. One milligram per day was enough to cause significant muscle growth. The higher the dose, the more muscle participants put on. In another trial, participants took doses as high as 22 mg/day with no side effects or safety issues [3]. In rats, LGD-4033 increases bone density, muscle mass, and sex drive, without damaging prostate or liver tissue [3].

LGD-4033 does not appear to stimulate fat loss, so if you take it on its own, it won’t make you leaner – just more muscular.
