About Retatrutide
What is retatrutide peptide?
Retatrutide peptide is a synthetic 39-amino-acid research peptide, catalogued in the literature as LY3437943. It is supplied as a lyophilized powder for in vitro laboratory use. The sequence is built on a modified GCG-family backbone with non-natural residues — Aib substitutions and an α-methyl-leucine — and a C20 diacid side chain conjugated to a lysine through an AEEA–γ-glutamate linker. That lipidation is what distinguishes the retatrutide peptide structurally from earlier single- and dual-receptor analogues.
How does retatrutide work?
In vitro, retatrutide is characterized as a triple agonist: it binds and activates the GLP-1, GIP and GCGR receptor families in the same assay system. Binding at each receptor is measured separately in receptor-expressing cell lines, and the lipid side chain governs its behaviour in protein-supplemented assay media, which is why it appears in extended-exposure assay designs. HEEZ supplies the compound; the assay design is the researcher's.
How HEEZ tests retatrutide
Retatrutide is produced by solid-phase peptide synthesis, purified by multi-stage reversed-phase chromatography and lyophilized. Every lot is sent to an independent third-party laboratory and analysed by HPLC for purity and mass spectrometry for identity. The result is published on a lot-specific certificate of analysis — the current lot's certificate is here: /coa/retatrutide-10mg-coa.webp. Purity is reported as measured rather than as a marketing floor.
Retatrutide for sale: sizes and format
Retatrutide is for sale from HEEZ Research in 10mg and 20mg sealed glass vials of freeze-dried powder. Sealed lyophilized vials are stable at ambient temperature in transit and ship at ambient temperature — same day on orders placed before 3 PM ET, via UPS 2nd Day Air or Overnight from the USA. Larger sizes carry a lower cost per milligram; the price per size is in the selector above.
