Description

Ligandrol is a novel nonsteroidal oral selective androgen receptor modulator being investigated as a potential treatment for conditions relating to muscle dystrophy and osteoporosis. Studies have found that a daily dose of LGD results in increased muscle mass and capillary density in rats. Testolone, also known as RAD 140, is being investigated for its potential ability to enhance muscle hypertrophy. Studies have found that 28-day dosing with RAD140 results in statistically significant increases in animal body weight.
