SARMs
SARMs
A drug class often marketed for muscle growth. The word “selective” is not a safety guarantee.
Investigational / safety concerns
Also known as: selective androgen receptor modulators · ostarine · enobosarm · ligandrol · LGD-4033 · RAD-140
Practical use
Applying the explained evidence
- Where it fits
- A drug class often marketed for muscle growth. The word “selective” is not a safety guarantee.
- Put the information into practice
- Do not treat “not a steroid” as proof of low risk. Compare the actual study population and outcome with a seller’s claims. Yellow eyes or skin, dark urine and significant abdominal pain warrant medical attention.
- Check the exact molecule
- Keep the named molecule separate from a broad category claim. Check whether a finding comes from a human intervention, laboratory mechanism or analytical test before interpreting it as a performance benefit.
- Keep this limit in view
- FDA reports serious liver injury and warns about cardiovascular, reproductive and psychiatric risks. Online products may have uncertain contents, even when labeled for research use.
Overview
Selective androgen receptor modulators act on androgen signaling. FDA warns that bodybuilding products marketed as SARMs are unapproved drugs, not legitimate dietary supplements. Individual compounds need individual evidence; this is a class overview.
Risks and limitations
FDA reports serious liver injury and warns about cardiovascular, reproductive and psychiatric risks. Online products may have uncertain contents, even when labeled for research use.
