Salt form is a specification
Tirzepatide carbonate and the sodium salt differ in mass and in stability. Our codes distinguish them so the quotation and the COA describe the same material.
Peptide range · Reproductive & metabolic
GLP-1, GIP and amylin analogues alongside the kisspeptin and melanocortin peptides — the largest range on this site, and the most regulated.
Overview
This range covers the incretin analogues — Tirzepatide, Retatrutide, Semaglutide, Liraglutide, Mazdutide and the amylin analogue Cagrilintide — together with glucagon and the reproductive-axis peptides: Kisspeptin-10, PT-141, Melanotan I and II, Gonadorelin, Triptorelin and Oxytocin.
These are prescription medicines in most markets. We supply them as research materials to laboratories and manufacturers, with a research-use statement on every document; we do not sell to consumers and we do not provide dosing information. When a GLP-1 quotation looks unusually cheap, the salt form or the assay basis is usually where the difference sits.
Catalogue
Every item below is a separate code with its own specification. Where a product exists in several salt forms, each form is listed and priced separately.
Specification
Three things decide whether two quotations for the “same” peptide are actually the same material.
Tirzepatide carbonate and the sodium salt differ in mass and in stability. Our codes distinguish them so the quotation and the COA describe the same material.
We supply the material and the documentation. Market authorisation, import licensing and labelling sit with the importer — we will not describe a product as approved anywhere it is not.
A 99% figure expressed on the salt is not 99% of the free peptide. Ask which basis the number is on before you compare two suppliers.
