DSIP
Sleep peptide Limited evidence 3 cited studies 76 live vendors
DSIP (delta sleep-inducing peptide) is a short endogenous nonapeptide first isolated from cerebral venous blood, widely catalogued as a neuropeptide research term. In laboratory settings it is studied for its interactions with sleep-related and neuroendocrine signaling in animal and in-vitro models. This index tracks research-use-only (RUO) vendor pricing for DSIP so researchers can compare cost across suppliers.
Evidence brief
DSIP (delta sleep-inducing peptide) is a nine-amino-acid peptide first isolated from rabbit blood and studied mainly in animal models of sleep, pain, and stress.

These figures are what pepmg still publishes about price: the floor, the middle, the spread and how many sources we track, computed from listings we captured first-party and refreshed on the same schedule as always. We no longer publish the individual listings or the sellers behind them.
Computed from 93 in-stock listings across 76 sources we captured first-party, with bulk vials, blends and statistical outliers excluded so the figures compare like with like. The spread is the highest tracked price divided by the lowest — how much the same milligram varies depending on where you look. The chart is the daily minimum; days we did not capture are left out rather than filled in.

- Delta-sleep-inducing peptide (DSIP): a review PubMed ↗
Since the turn of the century, it has been postulated that humoral factors induce sleep. Many compounds were proposed as sleep-factors, but only two of the sleep-peptides have been purified to homogeneity and characterized, so far. One of…
- Delta sleep-inducing peptide (DSIP): a still unresolved riddle PubMed ↗
Delta sleep-inducing peptide (DSIP) was isolated from rabbit cerebral venous blood by Schoenenberger-Monnier group from Basel in 1977 and initially regarded as a candidate sleep-promoting factor. However, the link between DSIP and sleep…

▸ Why compare $/mg for DSIP?
Per-mg prices for DSIP vary because vendors differ in synthesis scale, stated purity, fill quantity per vial, and lot testing overhead. Comparing normalized $/mg across suppliers helps a researcher gauge whether a listing is competitively priced rather than reflecting a smaller fill or lighter documentation.
▸ Reading the COA
For DSIP, confirm identity by mass spectrometry against the expected monoisotopic mass of the nonapeptide sequence (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu), and check that reported HPLC purity meets a stated threshold (commonly 98%+ for research material). Watch for common synthesis-related impurities such as truncated or deletion sequences and residual TFA counterions; a COA should show the HPLC chromatogram and MS trace, not just a summary percentage.
