RAD140 10 (Testolone) is a selective androgen receptor modulator (SARM). It is used in androgen replacement therapy as a substitute for testosterone. Each RAD140 10mg tablet contains 10mg of testolone along with excipients.SARMs like Testolone are molecules that act on androgen receptors. When stimulated by androgens, these receptors make male sexual characteristics (androgenic action) happen. They also cause the development of muscle bulk and bone mass (anabolic action). Testolone stimulates these receptors to produce an increase in lean body mass which is fat-free mass, and improvement of bone density - since they do not stimulate the receptors to cause the development of male sexual characteristics. SARMs do not cause prostate hypertrophy which is caused by exogenous androgens.Dosage: Take 1 tablet daily orally.Side effects include heart attack, liver injury.
