About Retatrutide
Retatrutide is a synthetic 39–amino-acid peptide engineered as a triple agonist at the GIP, GLP-1 and glucagon receptors. It belongs to the incretin-analogue class of research peptides and is one of the most frequently referenced compounds in current metabolic-signalling literature.
Purvexis supplies retatrutide as a lyophilised powder in sealed vials and as a measured spray, manufactured in the United States and released only after HPLC and mass-spectrometry identity and purity testing at ≥99%.
All dose options for this compound are listed on this page so a laboratory can select vial size or spray format without comparing separate listings.
Studied in the literature for
- Receptor-binding and selectivity assays across GIP, GLP-1 and glucagon receptors
- Comparative in-vitro signalling studies against single- and dual-agonist incretin analogues
- Peptide stability, reconstitution and storage-condition characterisation
- Analytical method development (HPLC, LC-MS) for incretin-class peptides
Handling and storage
- Supplied lyophilised under vacuum seal; reconstitute with bacteriostatic or sterile water
- Store sealed vials at 2–8 °C protected from light; long-term storage at −20 °C
- Avoid repeated freeze–thaw cycles and vigorous agitation during reconstitution
Retatrutide — Frequently Asked Questions
What is retatrutide?
Retatrutide is a synthetic peptide that acts as a triple agonist at the GIP, GLP-1 and glucagon receptors. It is studied in metabolic-signalling research as a successor to single- and dual-receptor incretin analogues. Purvexis supplies it as a research chemical only.
What is the difference between the retatrutide vial and the spray?
The vial contains lyophilised retatrutide powder for reconstitution in the laboratory, which gives full control over concentration. The spray is a pre-prepared solution in a metered device, chosen by labs that need consistent measured delivery without reconstitution. Both are the same ≥99% purity material.
What purity is your retatrutide?
Every retatrutide batch is tested by HPLC and mass spectrometry to ≥99% purity. A third-party certificate of analysis (COA) is available on request for the exact lot you receive.
Is retatrutide sold for human use?
No. retatrutide is supplied strictly as a research chemical for in-vitro and laboratory research use only. It is not a drug, food or dietary supplement, and it is not for human or veterinary use, diagnosis or treatment.
How should retatrutide be stored?
Lyophilised retatrutide is shipped at ambient temperature and is stable in transit. Store the sealed vial refrigerated at 2–8 °C, protected from light, for long-term storage; once reconstituted with bacteriostatic water, keep refrigerated and use within the window your protocol specifies.
How fast does retatrutide ship?
Every order ships free via USPS Priority Mail, typically arriving in 2–3 business days. Orders placed before the daily cut-off are packed the same business day, and tracking is emailed as soon as the label is generated.
≥99% purity, third-party COA verified, manufactured in the USA. For research use only — not for human or veterinary use.
