About Retatrutide

What is retatrutide peptide?

Retatrutide peptide is a synthetic 39-amino-acid research peptide supplied as a lyophilized powder for in vitro laboratory use. The sequence carries 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, ending in a C-terminal serinamide.

How is retatrutide supplied?

Retatrutide is a 39-residue synthetic peptide supplied as a lyophilized powder for in vitro research.

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 identity (retention time against a reference standard).

Retatrutide for sale: sizes and format
