Description and Benefit

RAD-140, also known as Testolone, is a SARM, a selective androgen receptor modulator. There is little danger of nonskeletal muscle tissues experiencing androgen activity. In fact, RAD-140 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 Testolone 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.



Half Life

16 hours.

Side Effects

None to date, including no effects on liver, kidneys, prostate, nor aromatase conversion (conversion of testosterone into estrogen).
