What is DSIP and what is Selank?
DSIP is classified as Synthetic nonapeptide; 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.
DSIP
Synthetic nonapeptide
DSIP (delta sleep-inducing peptide) is a synthetic nonapeptide, a nine-amino-acid sequence first isolated during neuropeptide fractionation studies and named for the electroencephalographic waveform observed in the animal model where it was characterized. Verve supplies it as a high-purity research compound for laboratory neuromodulation research.

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.
