Testostelone

RAD-140, also known as Testolone, has the highest ratio of anabolic to androgenic activity of any SARM discovered, 90:1. Testosterone has an anabolic to androgenic ratio of 100:100. This means that RAD-140 is almost as anabolic as testosterone while being only 1/100th as androgenic. This is a positive as most of the negative side effects of testosterone, including effects on liver, kidney and prostate, come from its androgenic effects.
