Incretin and amylin analogues are synthetic linear peptide amides filed under the conventional literature name for the group; the listings describe each member by chemistry only. The members with a published identity record carry non-coded 2-aminoisobutyric acid (Aib) residues, a C-terminal amide and a lysine whose side chain carries a linker and a C20 diacid group, so the listed molecular formula includes that side-chain group as well as the residues. The category can also carry other reference material the catalogue assigns to the same group. Each compound is supplied sealed at the nominal quantity printed on the label, as lyophilized powder in a vial for the peptide listings, and the product page states the CAS number, molecular formula, average molecular weight and, where recorded, the sequence and salt form.
Listed here: Tirzepatide, Retatrutide, Cagrilintide, 5-Amino-1MQ, MOTS-C, Mazdutide (15mg, 60mg, 10mg, 20mg, 30mg, 50mg, 40mg). Each product page lists the CAS number, molecular formula, molecular weight and, for peptides, the amino-acid sequence. Reported HPLC purity is shown per product; the HPLC and mass-spectrometry identity report is sent by email on request, before you order if you want to see it first.

Frequently asked questions
Which compounds are listed in the incretin and amylin analogue category?
This category currently lists 6 compounds: Tirzepatide, Retatrutide, Cagrilintide, 5-Amino-1MQ, MOTS-C and Mazdutide. Each is supplied sealed at the nominal quantity printed on the label, as lyophilized powder in a vial for the peptide listings. Each product page states the CAS number, molecular formula and average molecular weight, with the sequence and salt form where a record exists, and the reported HPLC purity for that listing. The compounds are described by chemistry, identity and sourced registry status only.
What makes a peptide an incretin or amylin analogue, chemically?
The name is the conventional literature grouping; the listings describe each member by chemistry only. The members with a published identity record are linear peptide amides with non-coded 2-aminoisobutyric acid (Aib) residues, a C-terminal amide and a lysine whose side chain carries a linker and a C20 diacid group, so the listed formula includes the side-chain group as well as the residues. Public registries do not always agree on the formula of these peptides; the product page states the value on the listing, and each compound guide notes where a registry record differs. The CAS numbers and molecular weights table lists every catalog entry.
How should sealed incretin analogue vials be stored?
Refrigerate sealed vials at 2–8 °C on arrival or store them at −20 °C for long-term storage, dry and protected from light. Compounds ship as lyophilized powder at ambient temperature without cold packs, because the dry solid is substantially more thermally stable than the same compound in solution. The peptide storage guide covers handling of the dry powder.
