What is Epitalon and what is Selank?
Epitalon is classified as Synthetic tetrapeptide; Selank as Synthetic heptapeptide. 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.

Synthetic heptapeptide
Selank is a synthetic heptapeptide, a seven-amino-acid chain built from the endogenous immunomodulatory tetrapeptide tuftsin with a C-terminal Pro-Gly-Pro extension added to increase stability. Verve supplies it as a high-purity research compound for neuroscience and peptide-signaling research.
full Selank profile →Which research models is each compound studied in?
Epitalon sits in longevity & cellular research and Selank in mind & sleep research, so their listed models largely do not intersect. The table lists 5 reported research applications for Epitalon and 5 for Selank. Rows are per compound, not equivalences.
| Epitalon — reported research applications | Selank — reported research applications |
|---|---|
| Telomerase-expression research models | Regulatory-neuropeptide signaling research |
| Pineal-peptide and circadian-signaling research | GABAergic and monoaminergic pathway research models |
| Chromatin and gene-regulation studies | Neurotrophic gene-expression studies |
| Cellular-senescence and replicative-aging research models | Tuftsin-analog structure–activity research |
| Short-peptide stability and synthesis research | Peptide-stability and degradation-kinetics research |
