Delta Sleep-Inducing Peptide (DSIP) is a regulatory nonapeptide supplied as 5 mg lyophilised solid for investigative analytics into peptide interactions within biochemical models and stress-response pathways. For research use only — not for human or animal consumption.

Every batch is verified at the manufacturer and re-tested when received in the UK. We send batches to a third-party UK lab where results cannot be manipulated — we do not rely on supplier testing or CoAs alone, so you get what you pay for. Each batch is independently analysed and supplied with a Certificate of Analysis (CoA) detailing purity, identity, and analytical method used. Batch-coded stock ensures full traceability from production to dispatch. Stock is held in laboratory-grade temperature-controlled storage and prepared using controlled thawing before dispatch. See our About page for full details. Additional documentation is available upon request for institutional procurement.
