Overview
Retatrutide is a synthetic investigational peptide developed as a multi-pathway agonist, representing the next generation of metabolic research compounds. It activates multiple target receptor subtypes for broad systemic effects studied in preclinical models.
History
Builds on decades of single- and dual-agonist research; uniquely integrates three pathway targets.
Structure and mechanism
Retatrutide is a synthetic peptide engineered as a triple agonist — active at three distinct receptor targets simultaneously — representing the current frontier of multi-pathway metabolic research compounds. It extends the design logic of single-pathway (semaglutide) and dual-pathway (tirzepatide) agonists by integrating a third pathway, glucagon-receptor activity, alongside the two.
In preclinical laboratory models the compound is studied for the broad, multi-system signaling that arises from co-activating three pathways, and it is frequently used as the reference point in triple- vs. dual-agonist comparative work. Its molecular weight (4,845.44 g/mol) and formula (C₂₂₁H₃₄₂N₄₆O₆₈) sit close to tirzepatide's, but its receptor-engagement profile is distinct.
Reconstitution and handling (research use)
Wholesale retatrutide ships as a lyophilized powder. For in-vitro laboratory use it is reconstituted with bacteriostatic or sterile water, with diluent volume chosen to reach the assay's target concentration. Lyophilized material is generally stored at -20°C and protected from light; reconstituted solution is refrigerated at 2–8°C and used within the working window the study defines.
These notes cover general laboratory handling of a chemical reagent only — not human or veterinary use.
Wholesale sourcing notes
Retatrutide is among the fastest-growing compounds in wholesale research demand, stocked in 10 mg and higher presentations. Every lot is US-sourced and independently verified by a third-party lab for identity, purity, and quantitation, with a per-lot COA included in every order.
Pricing is quoted by volume across 100, 250, 500, and 1,000-vial bands under a 3-kit (30-vial) minimum per order, mix and match, with a lower price band unlocking at 1,000 vials across the whole order.
