Both are discussed in mitochondrial papers, for different reasons

MOTS-C 20 mg is a mitochondrial-derived peptide studied in cellular energy, stress-response, and AMPK-pathway models. SS-31 10 mg is studied in mitochondrial membrane and cardiolipin-associated models, including oxidative-stress assays. Literature may also call SS-31 elamipretide. The Janoshik test title uses that name.

Sharing the word mitochondrial does not make the sequences, the labeled amounts, or the endpoints interchangeable.

One report is milligrams, the other prints a percent

MOTS-C task 193720, batch MC-20, analysis June 22, 2026, prints 23.38 mg and purity 99.198%. SS-31 task 172219, batch S-10, analysis June 19, 2026, prints 13.72% and purity 99.634%. Leave the 13.72% as a percent. Do not turn it into milligrams.

The SS-31 catalog label remains 10 mg. The percent on the report is not a new label amount.

Price

MOTS-C 20 mg is $64.99. SS-31 10 mg is $49.99. Buy one, get one 50% off. NAD+ is a cofactor, not a third peptide in this pair, if the question is cellular energy rather than these two sequences.
