DSIP 2mg

DSIP (Delta Sleep-Inducing Peptide, CAS 62568-57-4) is a 9-amino acid neuropeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) with molecular weight 848.86 Da. It was first isolated from rabbit cerebrospinal fluid by Monnier et al. in 1977. Preclinical research has studied it for: increasing delta-wave (slow-wave) sleep amplitude and duration; modulation of corticotropin-releasing hormone (CRH) and ACTH pathways relevant to HPA axis stress research; antioxidant and neuroprotective activity in neuronal oxidative stress models; and interactions with LH and GH secretion in neuroendocrine research contexts. It is regarded as one of the earliest-characterised endogenous sleep peptides. For research use only.

DSIP, Semax, and Selank are mechanistically distinct. Semax is an ACTH(4-7) analogue studied primarily for cognitive enhancement via BDNF upregulation and dopaminergic pathway modulation. Selank is a tuftsin analogue investigated for anxiolytic effects through GABAergic and serotonergic systems. DSIP's primary research focus is specifically on sleep architecture — particularly slow-wave delta sleep — and HPA axis stress modulation. Where Semax and Selank are primarily studied for daytime cognitive and anxiety parameters, DSIP's research profile centres on the sleep-wake cycle and nocturnal restorative physiology.

Reconstitution: Draw 1–2mL of bacteriostatic water into a clean 31G insulin syringe. Inject slowly down the inner glass wall of the DSIP vial and swirl gently until dissolved — do not shake or vortex. The solution should be clear and colourless. Common concentration: 1mL BAC water into 2mg vial = 2mg/mL (2000mcg/mL). Storage: Lyophilised powder — store at −20°C for up to 24 months, protected from light. Reconstituted solution — refrigerate at 2–8°C and use within 28 days. Avoid repeated freeze-thaw cycles of the reconstituted solution.

DSIP is legal to purchase in Australia for legitimate laboratory research purposes. It is not listed as a scheduled substance under the Poisons Standard when sold for research use only. Purchasers must confirm they are 18+ and purchasing for research use only. It is not TGA-approved for human consumption, therapeutic, veterinary, or cosmetic use. Our DSIP 2mg is independently verified at 99.1% HPLC purity with full COA documentation including mass spectrometry identity confirmation.

DSIP has CAS number 62568-57-4, molecular formula C35H48N10O15, and molecular weight 848.86 Da. Its amino acid sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu — a nonapeptide of 9 residues. It was originally isolated in pure form from venous blood of rabbits with thalamic stimulation-induced sleep. Identity in our batch is confirmed via mass spectrometry as documented in the COA.
