About DSIP (Delta Sleep-Inducing Peptide)
Buy DSIP 5mg at IGF1 Shop. DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) originally isolated by Schoenenberger and Monnier in 1977 from cerebral venous blood during electrostimulated sleep. DSIP has been extensively studied for its effects on slow-wave sleep architecture, stress response modulation, and circadian rhythm normalization. Each DSIP 5mg vial is HPLC ≥99% pure, ESI-MS verified, with a per-lot Certificate of Analysis. CAS 62568-57-4.

FAQ
DSIP (Delta Sleep-Inducing Peptide) — Frequently asked questions
What is DSIP?
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from cerebral venous blood during electrostimulated sleep. Studies describe effects on slow-wave sleep architecture, stress response, and circadian rhythm. CAS 62568-57-4.
How is DSIP typically used?
DSIP is most commonly dosed at 100-300 mcg subcutaneously 1-2 hours before bedtime. Each 5mg DSIP vial reconstituted with 2mL bacteriostatic water yields 250 mcg per 0.1mL on a U-100 insulin syringe.
How is DSIP tested?
Each DSIP lot is HPLC-tested to ≥99% purity, confirmed by ESI mass spectrometry against the theoretical 848.85 Da molecular weight, and LAL endotoxin tested below 0.5 EU/mg.
How do I store DSIP?
Lyophilized DSIP is stable at -20°C for 24+ months. After reconstitution with bacteriostatic water, store refrigerated at 2-8°C and use within 30 days.
