What is Selank and what is Semax?
Selank is classified as Synthetic heptapeptide; Semax as Synthetic heptapeptide · neuro 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.
Selank
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.
