Overview
LGD-4033, commonly called Ligandrol and also catalogued as VK5211, is a non-steroidal selective androgen receptor modulator. Chemically it is a benzonitrile bearing a trifluoromethyl group and a pyrrolidine ring with a trifluoro-hydroxyethyl substituent, and it is not a peptide or a hormone — it is a small synthetic organic molecule that binds the androgen receptor ligand-binding domain.

Questions about LGD-4033 (Ligandrol)
Is LGD-4033 a peptide?
No. It is a small synthetic organic molecule with a molecular weight of about 338 g/mol — a benzonitrile derivative, not an amino acid chain. It is grouped with research compounds rather than peptides and requires no reconstitution or cold-chain storage.
Is it approved or legal to sell as a supplement?
No. LGD-4033 is not an approved drug in any jurisdiction and is not a dietary supplement or dietary ingredient. United States regulators have issued warnings about SARMs sold as supplements. It is supplied here strictly as a research chemical for laboratory use.
What does the published research cover?
Work to date spans androgen receptor binding and coregulator recruitment in vitro, rodent studies comparing muscle, bone and prostate endpoints, a Phase 1 pharmacokinetic and hormone-marker study in healthy men, and a substantial anti-doping analytical literature on detection methods.
What purity and documentation are supplied?
Each lot is tested by HPLC to at least 98% purity with identity confirmation, and a lot-matched certificate of analysis is available. Independent analyses of consumer SARM products have often found mislabelling, which is why lot-level documentation matters for this class.
Is it detectable in anti-doping testing?
Yes. LGD-4033 is listed by the World Anti-Doping Agency as a prohibited anabolic agent, and validated LC-MS/MS assays detect the parent compound and its metabolites with long detection windows. Much of the published analytical literature exists for exactly this purpose.
