What is the difference between MOTS-C and SS-31 (Elamipretide)?

The main difference is mechanism and research stage. MOTS-C targets Mitochondrial-derived peptide (preclinical / early research) and is studied for metabolism & insulin-sensitivity research; SS-31 (Elamipretide) targets Cardiolipin-binding tetrapeptide (investigational) and is studied for mitochondrial-function research. Both are research-use-only compounds, not for human or animal use.

Are MOTS-C and SS-31 (Elamipretide) approved for human use?

No. Renova Wellness supplies both strictly for in-vitro laboratory and scientific research use only. Research status differs — MOTS-C: preclinical / early research; SS-31 (Elamipretide): investigational — but neither is sold for human or animal consumption, and no medical, therapeutic, or dosing claims are made.

How is purity verified for MOTS-C and SS-31 (Elamipretide)?

Every lot of both compounds ships with its own per-batch Certificate of Analysis — identity by mass spectrometry, ≥98% purity by HPLC, and a unique lot number you can verify against the vial in your hand.

Research Comparison

MOTS-C vs SS-31 (Elamipretide)

MOTS-C and SS-31 (Elamipretide) are often compared because both sit in mitochondrial research. MOTS-C acts on mitochondrial-derived peptide and is studied for metabolism & insulin-sensitivity research, while SS-31 (Elamipretide) acts on cardiolipin-binding tetrapeptide and is studied for mitochondrial-function research. Both are supplied as lyophilized powder for in-vitro laboratory research only — this page compares mechanism and research status, not dosing or human use.
