01

What the name refers to

A non-steroidal selective androgen receptor modulator studied preclinically and sold online without approval for human use.

02

Evidence and regulatory context

No broadly authorised human medicine is established for this entry. Published evidence may be preclinical, early-stage or sparse, and a research label is not a quality or safety certification.

03

Reading product records

Research-market surveys have repeatedly found label mismatches in this category. A record should therefore keep the claimed molecule, measured identity and measured amount separate, and should never treat the word “SARM” as evidence of approval or safety.

Primary research links

Use current regulator and study records rather than treating a catalogue description as medical evidence.
