Sarms  S-4

Andarine (S4), also known as Gtx-007, is a selective androgen receptor modulator (SARM) currently under investigation as a pharmaceutical treatment for muscle loss and age-related weakness. Although often marketed in the black market as a SARM, Andarine is not actually a SARM. This medication is being researched for the treatment of growth hormone deficiency and has the potential to increase muscle mass, metabolism, energy, fat burning, and bone strength. Remember that the use of Andarine should always be consulted with a healthcare professional.
