Testolone or RAD140 is an investigative drug that is being developed by Radius Health and is being researched for potential therapeutic applications.
It is a fairly recent addition to the world of SARMS, considering that the first animal studies were conducted in 2011. However, it is already being considered by many as one of the most promising new developments.
Like most other SARMS, RAD140 has a strong affinity for the androgen receptor and it stimulates an effect in the body that is very identical to anabolic steroids. However, it does not affect the prostate gland in men or cause androgenic symptoms in women.
Testolone helps increase muscle mass dramatically with no elevation of liver enzymes. It is fully effective while stimulating muscle tissue but only partially effective on the prostate gland. This makes it a great choice for treating cachexia and age-related muscle wasting.
