Research objective

Peptides for Sleep

Compounds studied against sleep architecture, circadian rhythm and the stress axis. DSIP is the core of it — an endogenous nonapeptide, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu at 848.81 g/mol, which carries the EEG delta-activity and corticotropin literature — with research-grade melatonin, an indoleamine rather than a peptide, as the chronobiology comparator. The pineal bioregulators Epitalon and Pinealon sit alongside both, several items appear as nasal sprays as well as vials, and the circadian small molecules fill out the rest. A narrower literature than the nootropic shelf, and the groupings reflect that.
