Description

Ligandrol is a potential treatment for conditions relating to muscle dystrophy and osteoporosis. Recent studies investigating the effects of LGD 4033 on muscle tissue found that a daily dose of LGD resulted in a higher number of capillaries in all muscles studied, and that the LGD treatments resulted in a significantly higher body weight in rats. Testolone, also known as RAD 140, is being investigated for its potential ability to enhance muscle hypertrophy. Studies have found that dosing with RAD140 for 28 days was statistically significant in terms of increasing animal body weight.
