UK supplier comparison

Use the filters to pick a size and presentation (vial, pen or serum) and compare like for like, or view every size on a £ per mg basis. Delivery is shown separately because it varies by supplier and order size. Offers whose outbound link failed our last check stay listed but rank below working links.

For in-vitro laboratory research only

DSIP is listed here as a research material. It is not for human or veterinary consumption, and nothing on this page is medical advice or dosing guidance. PeptideCompare is paid by flat supplier fees — never by sales commission or referral — so a price ranks by its number, not by who pays. We do not sell, test or verify any product, and quality or CoA labels are suppliers’ own claims. Always check the final price, documentation and legality with the supplier yourself.

Research profile

About DSIP in the lab

Named for early observations in rabbits, though its physiological role and receptor remain unresolved. It is used chiefly in peptide-chemistry and neurobiology reference work.

Proposed mechanism

Its physiological receptor and role remain unresolved. Proposed interactions include GABAergic and glutamatergic modulation and effects on stress-hormone release, but findings are inconsistent across studies.

Structure note

Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.

Amino-acid sequence (one-letter)

WAGGDASGE

Typical research themes

  • Neuropeptide biochemistry
  • Peptide degradation
  • Receptor de-orphanisation questions
