Cardarine (GW-501516)

**Class:** SARM (Selective Androgen Receptor Modulator)

Cardarine (GW-501516) and Ostarine (MK-2866/Enobosarm) are two distinct chemical compounds frequently discussed in the contexts of metabolic research, sports science, and clinical muscle wasting. While they are often marketed together in the "SARM" (Selective Androgen Receptor Modulator) category, t

YK-11 (17α,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester is a synthetic compound classified as a Selective Androgen Receptor Modulator (SARM). Unlike traditional non-steroidal SARMs such as Ostarine or Ligandrol, YK-11 possesses a steroidal

Testolone (RAD-140) is a potent, non-steroidal selective androgen receptor modulator (SARM) originally developed by Radius Health, Inc. It was designed to overcome the limitations of conventional androgen therapy, such as prostate enlargement and virilization, by exhibiting high tissue selectivity.

Cardarine (GW-501516) is a synthetic peroxisome proliferator-activated receptor delta (PPARδ) agonist originally developed through a collaboration between Ligand Pharmaceuticals and GlaxoSmithKline (GSK) for the treatment of metabolic and cardiovascular diseases. Although frequently categorized as a

Andarine (also known as S-4 or GTx-007) is an early-generation, nonsteroidal selective androgen receptor modulator (SARM) belonging to the aryl propionamide class. Developed initially for the treatment of conditions such as muscle wasting and osteoporosis, Andarine demonstrates high affinity for the
