Retatrutide is A triple-agonist research peptide that activates GLP-1, GIP, and glucagon receptors in laboratory studies. All ThePeptideCode products are laboratory research use only.

Mechanism & background

Retatrutide is a synthetic 39-residue peptide modified with a fatty-acid tail (similar in design to tirzepatide and semaglutide) so it binds albumin and circulates for several days in research models. Unlike tirzepatide which targets GLP-1 + GIP, retatrutide adds glucagon-receptor activity, which in animal and early human research has been associated with the largest reductions in body-mass observed in this drug class.

Common research applications

Laboratory weight-loss studies, glycaemic-control models, comparative pharmacokinetics versus tirzepatide and semaglutide, dose-ranging research.

Reconstitution and storage

Retatrutide ships as a lyophilised powder in a sealed glass vial. Reconstitute with bacteriostatic water following the step-by-step reconstitution guide. Once reconstituted, store at 2–8 °C for short-term use, or aliquot and freeze at −20 °C for longer storage. See the full dosage and storage guide.

Purity and batch verification

Every Retatrutide batch shipped by ThePeptideCode is verified by an ISO 17025-accredited independent laboratory using HPLC (purity) and mass spectrometry (identity). Typical purity is ≥99%. Look up your batch ID on the verification page.
