Retatrutide (GLP-1 RT) Triple Agonist for Research
Technical Overview
Retatrutide (GLP-1 RT) is a synthetic research peptide supplied exclusively for controlled laboratory research. It is used in experimental models that examine how three connected metabolic receptor systems interact: the glucagon-like peptide-1 (GLP-1) receptor, the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon receptor.
Research applications
- Receptor binding: binding characteristics at the GLP-1, GIP and glucagon receptors.
- Pathway selectivity: how activity is distributed across the three receptor pathways.
- Cellular signaling: downstream signaling events that follow receptor engagement.
- Receptor cross-talk: the relationship between interconnected metabolic and endocrine receptor systems.
Retatrutide is intended for analytical, in vitro and other appropriately designed nonclinical research carried out by qualified professionals. Research area: metabolic and endocrine receptor signaling.

Supplied as a lyophilized (freeze-dried) powder for stability and ease of reconstitution, in 5 mg, 12 mg, 24 mg, 30 mg and 60 mg vials. Store lyophilized at −20 °C, protected from light and moisture.

Storage Instructions
Handling and Storage Tips:
- On arrival, store the sealed vial at −20 °C, protected from light and moisture.
- For short-term storage (days to weeks), refrigeration at 2–8 °C is acceptable.
- Lyophilized peptides tolerate room temperature for short periods, such as during shipping.
- Let the vial reach room temperature before opening, to avoid condensation.
- Once reconstituted, keep refrigerated at 2–8 °C and avoid repeated freeze–thaw cycles.

Answers
Frequently Asked Questions
Is Retatrutide third-party tested?
Yes. Each lot is tested by Bioviridian, an independent HPLC-MS laboratory, for identity (mass spectrometry), purity (RP-HPLC), content and endotoxin, and the Certificate of Analysis is published for that lot.
Can I see the Certificate of Analysis before buying?
Yes. Download it from the Documents section above, or search the lot number in our COA library.
What does 'Research Use Only' mean?
Products are supplied only for laboratory research. They are not drugs, foods, supplements or cosmetics and are not for human or veterinary use.
How is it shipped and stored?
Cold-packed with tracking, same day on orders by 2 PM ET. Store lyophilized vials at −20 °C on arrival.
