How DSIP Works

DSIP is a nonapeptide originally isolated from rabbit cerebral venous blood during electrically induced sleep. It promotes delta-wave (slow-wave) sleep by modulating neuroendocrine signaling, although its exact receptor has not been definitively identified. DSIP modulates corticotropin and cortisol levels, influences the hypothalamic-pituitary-adrenal axis, has analgesic properties through opioid system modulation, and exhibits antioxidant effects. It normalizes disrupted sleep architecture and has stress-protective effects on multiple organ systems.

Reconstitution Calculator

Add this much bacteriostatic water:
2.0 mL
2 mg DSIP + 2.0 mL BAC water = 1 mg/mL

Inject bacteriostatic water slowly along the vial wall. Gently swirl until dissolved — never shake. Store reconstituted solution at 2-8°C and use within 30 days.

Frequently Asked Questions

DSIP (CAS: 62568-57-4) is a research compound, with a molecular weight of 848.81 Da in the Cognitive / Neuropeptides category. DSIP is a nonapeptide originally isolated from rabbit cerebral venous blood during electrically induced sleep. It promotes delta-wave (slow-wave) sleep by modulating neuroendocrine signaling, although its exact receptor has not been definitively identified. Researchers commonly investigate DSIP for Sleep architecture and delta-wave sleep promotion, Stress response and HPA axis modulation, Pain modulation and analgesia. Every vial from MiPeptidos includes batch-specific analytical documentation.
DSIP is available in 2 sizes (2mg, 5mg), so reconstitution volume depends on which vial you have. For the 2mg size, add 1mL of bacteriostatic water; for the 5mg size, use 1-2mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted DSIP at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
DSIP (Delta Sleep-Inducing Peptide, 849 Da) and Pinealon (418 Da) both influence sleep pathways but through different mechanisms. DSIP is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) that modulates delta-wave sleep architecture and has stress-protective effects via modulation of corticotropin and somatotropin release. Pinealon is a tripeptide that regulates pinealocyte gene expression and melatonin synthesis. DSIP has a broader endocrine profile. MiPeptidos offers both for sleep and circadian research.
Store lyophilized DSIP at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, DSIP has a reported half-life of ~15-25 minutes in plasma, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every DSIP order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-DSIP-2600215, tested January 19, 2026) shows 99.7% purity by HPLC, mass spectrometry confirmation at 848.81 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
