DSIP (Delta Sleep-Inducing Peptide, MW 848.86 Da) is a neuropeptide studied for sleep and stress research. It has stricter storage requirements than many peptides, which is the key sourcing consideration.
What to Look for When Sourcing DSIP
Require a third-party COA (HPLC) confirming ≥98% purity and the 848.86 Da molecular weight, in sealed lyophilized vials.
Typical Price Range
Research-grade DSIP typically costs about $30–$60 per vial.
Storage and Handling
Lyophilized DSIP is best stored frozen (around -20°C) for stability; short ambient periods during shipping are acceptable. Reconstituted peptide requires refrigeration at 2–8°C and prompt use.
Red Flags to Avoid
Missing COAs, no frozen-storage guidance, prices far below market, and human-use claims.
