What is Epitalon and what is KLOW?
Epitalon is classified as Synthetic tetrapeptide; KLOW as Four-peptide research blend · cellular research. 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.

Four-peptide research blend · cellular research
KLOW is a research blend that combines four of the most-studied peptides (BPC-157, TB-500, GHK-Cu, and KPV) in a single vial. Verve supplies it as a high-purity, batch-tested research preparation for cellular research.
full KLOW profile →Which research models is each compound studied in?
Epitalon sits in longevity & cellular research and KLOW in recovery & gut research, so their listed models largely do not intersect. The table lists 5 reported research applications for Epitalon and 4 for KLOW. Rows are per compound, not equivalences.
