LGD-3303
LGD-3303 is a SARM — a selective androgen receptor modulator (a lab-made molecule that switches on the body's androgen, or male-hormone, receptors in some tissues but not others). It is not a peptide, and it is not a steroid. It came out of the same Ligand Pharmaceuticals research program as…
Testolone
Testolone (RAD-140) is a selective androgen receptor modulator, or SARM (a drug that switches on the body's testosterone-sensing receptor in a targeted way). It is a small molecule made in a lab — not a peptide, and not an anabolic steroid. It was created as an experimental drug, was never approved…
