Semax, Selank, DSIP, Cerebrolysin, P21, Pinealon, Melatonin, VIP. Neuropeptide reagents for cognitive, mood, sleep-architecture, and social-behaviour research.
Who sources this class & for what
Cognitive and neuropeptide buyers are predominantly research labs running in vivo rodent studies. The dominant administration route in the published literature is intranasal — Semax, Selank, DSIP, Pinealon — because these peptides are not meaningfully blood-brain-barrier permeable when delivered systemically. For in vivo workflows, endotoxin and microbial-limit testing is recommended at the CoA stage so the bioassay readout is not confounded by contamination unrelated to the test article.
