About sleep peptides
Sleep peptides include DSIP (Delta Sleep-Inducing Peptide) and emerging compounds targeting deep-sleep stages and circadian regulation. Reviewer feedback tends to focus on sleep onset speed and morning grogginess — two metrics that are easy to track personally.
DSIP is on the FDA's July 24, 2026 PCAC review agenda alongside Epitalon and Semax. Vendor availability is solid but the regulatory picture is shifting.
