Epitalon vs KPV
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epitalon
Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.
Full details →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.

| Aspect | Epitalon | KPV |
|---|---|---|
| Dose Range | 5 mg–10 mg | 200 mcg–500 mcg |
| Frequency | 1x daily | 1x daily |
| Cycle Length | 2–3 weeks | 4–8 weeks |
| Route | subcutaneous | subcutaneous |
| Mechanism | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. | Inhibits NF-κB activation and reduces inflammatory cytokine production. Enters cells and directly modulates inflammatory signaling without requiring melanocortin receptors. |
| Typical Dosage | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. | Oral/sublingual: 200-500mcg 1-3 times daily. Topical formulations for localized inflammation. Also used in enemas for gut inflammation. |
| Administration | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. | Can be taken orally, sublingually, or as suppositories/enemas for gut inflammation. Topical use for skin conditions. Stable orally unlike most peptides. |
| Side Effects | Generally well-tolerated. May affect sleep patterns initially. | Generally very well-tolerated. Minimal systemic effects due to targeted anti-inflammatory action. |
