Frequently asked questions
What is MOTS-c?
MOTS-c is a 16-amino-acid peptide encoded in the mitochondrial genome, about 2,175 Da as the free base. Peptryn supplies it as a 40mg lyophilized laboratory material.
What purity is Peptryn’s MOTS-c?
Peptryn’s MOTS-c is verified at 99.78% purity by HPLC-UV-MS, tested by MZ Biolabs (lot 2026-07-07). Read the COA. HPLC purity is area percent, the share of the main peak among all detected peaks; see our guide to peptide purity for what that means.
How is MOTS-c stored?
Store lyophilized powder at -20°C, protected from light and repeated freeze-thaw cycles.
What is MOTS-c’s CAS number?
MOTS-c’s CAS number is 1627580-64-6. Molecular weight: 2,174.6 g/mol (free base).
Is MOTS-c for human use?
No. Peptryn sells it for laboratory research only, and it is not approved for human or veterinary use. We do not give dosing or administration guidance.
Is MOTS-c the same as SS-31?
No. Both are studied in mitochondrial research but are different peptides. MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA, about 2,175 Da. SS-31 (elamipretide) is a synthetic tetrapeptide, about 640 Da. Peptryn sells both.
