You can buy DSIP from HEEZ Research, which stocks it in a single 5 mg lyophilized vial and ships from the USA. Everything HEEZ supplies is for in vitro laboratory research — not for human or veterinary use.
DSIP is a nonapeptide — nine amino acids — catalogued under that acronym rather than under a systematic chemical name. Its sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, it weighs approximately 849 daltons, and HEEZ supplies it as a synthetic peptide.
HEEZ Research sells DSIP in a single 5 mg lyophilized vial. DSIP shares that mass with AOD-9604 and the smaller BPC-157 format.
Yes — DSIP from HEEZ Research is independently tested by an accredited third-party laboratory using HPLC for purity and mass spectrometry for identity. Every peptide we supply is over 99% pure. Certificates of Analysis are published on the product page as testing is completed — review the report before you order. A certificate records the identity, purity and quantity measured for the material supplied, so you can confirm what you received matches what was ordered.
Sealed lyophilized DSIP vials are stable at ambient temperature in transit and ship without cold packaging. On arrival, store the sealed vial per the storage conditions on its certificate of analysis.

About DSIP
What is DSIP peptide?
DSIP peptide is a nonapeptide — Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu — first isolated in the 1970s and one of the earliest sequenced small peptides in the literature, supplied by HEEZ Research as a synthetic lyophilized powder for in vitro laboratory use.
How does DSIP work?
DSIP has no defined receptor target; in vitro it is characterized by its binding behaviour and stability, and its simple, well-documented mass makes it a standard reference sequence in peptide-analysis method development.
How HEEZ tests DSIP
Solid-phase synthesis, reversed-phase purification, lyophilization.
