DSIP 5mg (Delta Sleep-Inducing Peptide) Overview

DSIP 5mg from Peptide Science is the synthetic 9-amino-acid Delta Sleep-Inducing Peptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, supplied as a lyophilised vial for in-vitro and preclinical neuroscience research. The compound was originally isolated from cerebral venous blood of rabbits in slow-wave sleep and is named for the delta-wave EEG modulation observed in animal-model studies.

Compound Class and Mechanism

DSIP has been characterised in preclinical research for measurable effects on delta-wave EEG patterns in animal models, with reported additional activity at adrenocortical and somatotropic pathways at the cellular level. The peptide does not bind a single classical receptor with high affinity; instead, its activity profile spans multiple downstream signalling pathways related to circadian and sleep regulation. Browse the broader nootropic and sleep peptide range.

Reconstitution and Handling

The lyophilised vial reconstitutes with bacteriostatic water at the working concentration set by the principal investigator. Aliquoting reconstituted stock for single-use frozen storage is the standard preclinical handling practice cited in peptide-research literature.

Quality and Shipping

Each batch passes HPLC at greater than 99 percent purity, with mass-spectrometry identity confirmation against the theoretical molecular weight. A Certificate of Analysis accompanies every order. Material is filled in a US laboratory under ISO 9001:2015-aligned quality systems and dispatched in temperature-monitored insulated packaging via overnight or two-day courier.
