1. Description

Retatrutide is a synthetic peptide that has been described in published preclinical literature as a single-molecule triple-agonist scaffold engaging three incretin/metabolic receptor families:

GLP-1 (glucagon-like peptide-1) receptor
GIP (glucose-dependent insulinotropic polypeptide) receptor
Glucagon receptor

It is supplied by Peptide Logix as a lyophilized reference standard for in-vitro laboratory study only.

2. Reported characterization

Class: Synthetic peptide (triple-agonist scaffold)
Molecular weight: ~4731 Da (confirm against your lot CoA)
Form: Lyophilized powder, sealed amber vial
Solubility: Water-soluble; reconstitute in bacteriostatic water

The Certificate of Analysis shipped with each lot lists the exact measured mass and HPLC purity.

3. Storage and handling

Store sealed lyophilized vials at −20 °C, protected from light.
Warm vials to room temperature before opening to prevent atmospheric moisture condensation.
Reconstitute in bacteriostatic water at the concentration required by the study protocol.
After reconstitution, store the working solution at 2–8 °C and use within the working window specified for the lot.
Avoid freeze-thaw cycles of the reconstituted solution.

See the Storage Guide and Reconstitution Guide for general laboratory practice.

4. Quality assurance

Each Retatrutide lot supplied by Peptide Logix ships with a Certificate of Analysis showing reverse-phase HPLC purity and mass-spectrometry confirmation of the correct molecular mass. Read How to Verify Peptide Purity for guidance on interpreting the CoA.
