— FAQ
Retatrutide questions, answered
- 01
What is retatrutide?
Retatrutide is an investigational 39-amino-acid peptide engineered as a triple agonist of the GLP-1, GIP, and glucagon receptors (CAS 2381089-83-2) — one of the most closely watched molecules in metabolic research. Veritas supplies it strictly for laboratory research use.
Related compounds are listed in the GLP-1 & metabolic category.
- 02
Which retatrutide vial sizes are available?
Retatrutide is offered in 5 mg, 10 mg, 15 mg, and 20 mg research vials so laboratories can match vial size to protocol scale and minimize left-over solution. The reconstitution calculator helps plan reconstitution concentrations with Bacteriostatic Water for any of the four sizes.
- 03
How should retatrutide be stored?
Keep lyophilized vials refrigerated (2–8 °C) and protected from light; −20 °C is appropriate for long-term storage. Reconstituted solutions belong in the refrigerator — see our stability data for peptide-specific windows.
- 04
How is each retatrutide lot verified?
Each lot passes in-house reverse-phase HPLC and is re-confirmed by an independent laboratory via mass spectrometry; recent retatrutide lots have assayed at ~98.5% purity. Certificates are published per batch in the COA index.
