Do peptides like epitalon, MOTS-c and humanin slow aging?

Background

A group of research peptides is promoted online for anti-aging, including epitalon, MOTS-c, humanin, SHLP2 and SS-31. Several come from mitochondrial biology or Russian pineal research.

What the human research shows

• Most evidence comes from cell and animal studies.
• Human data are mostly observational (for example, blood levels falling with age) or from small studies by a single research group.
• SS-31 (elamipretide) is the exception, with randomized trials in specific mitochondrial diseases, not in aging.

What we still don’t know

• Whether any of them extend healthspan or lifespan in people.
• Long-term safety, dosing and the quality of products sold online.

Safety and status

None is approved as an anti-aging treatment. Since October 2026, some (including epitalon and MOTS-c) may be compounded by licensed pharmacies under FDA enforcement discretion, which is not approval.
