What is Epitalon and what is KPV?
Epitalon is classified as Synthetic tetrapeptide; KPV as Tripeptide alpha-MSH fragment. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
Epitalon
Synthetic tetrapeptide
Epitalon is a synthetic tetrapeptide with the sequence alanyl-glutamyl-aspartyl-glycine (Ala-Glu-Asp-Gly), developed as a short synthetic analog of a peptide fraction isolated from the pineal gland. It is a small, water-soluble peptide and one of the most frequently cited reference compounds in pineal-peptide and cellular-aging research literature.

Tripeptide alpha-MSH fragment
KPV is a tripeptide composed of lysine, valine, and proline, corresponding to the C-terminal fragment (residues 11–13) of alpha-melanocyte-stimulating hormone (alpha-MSH). It is the smallest sequence retained from that parent peptide and is widely used as a compact reference compound in cellular signaling research, where its short chain length makes it convenient for controlled in-vitro work.
full KPV profile →Which research models is each compound studied in?
Epitalon sits in longevity & cellular research and KPV in recovery & gut research, so their listed models largely do not intersect. The table lists 5 reported research applications for Epitalon and 5 for KPV. Rows are per compound, not equivalences.
| Epitalon — reported research applications | KPV — reported research applications |
|---|---|
| Telomerase-expression research models | Inflammatory-signaling research models (NF-κB pathway studies) |
| Pineal-peptide and circadian-signaling research | Cytokine-expression research in cultured cells |
| Chromatin and gene-regulation studies | Melanocortin-receptor and alpha-MSH fragment research |
| Cellular-senescence and replicative-aging research models | Epithelial and mucosal-barrier research models |
| Short-peptide stability and synthesis research | Structure–activity studies of short peptide fragments |
