KPV vs SS-31 (Elamipretide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
KPV
KPV is a tripeptide (Lys-Pro-Val) derived from alpha-melanocyte-stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of the parent hormone without the tanning or other melanocortin effects.
Full details →SS-31 (Elamipretide)
SS-31, also known as Elamipretide or Bendavia, is a mitochondria-targeted tetrapeptide. It has been studied extensively for mitochondrial diseases, heart failure, and age-related decline in mitochondrial function.

| Aspect | KPV | SS-31 (Elamipretide) |
|---|---|---|
| Mechanism | Inhibits NF-κB activation and reduces inflammatory cytokine production. Enters cells and directly modulates inflammatory signaling without requiring melanocortin receptors. | Concentrates in the inner mitochondrial membrane where it binds to cardiolipin, stabilizing electron transport chain function, reducing reactive oxygen species, and improving ATP production efficiency. |
| Typical Dosage | Oral/sublingual: 200-500mcg 1-3 times daily. Topical formulations for localized inflammation. Also used in enemas for gut inflammation. | Clinical trials have used IV infusions of 0.25mg/kg for acute conditions. Subcutaneous dosing protocols for research use typically range from 1-5mg daily. |
| Administration | Can be taken orally, sublingually, or as suppositories/enemas for gut inflammation. Topical use for skin conditions. Stable orally unlike most peptides. | Can be administered IV or subcutaneously. Most clinical research has used IV administration for cardiac conditions. |
| Side Effects | Generally very well-tolerated. Minimal systemic effects due to targeted anti-inflammatory action. | Generally well-tolerated. Clinical trials reported injection site reactions and occasional headache. |
