Retatrutide
Retatrutide is a synthetic single-chain peptide engineered as a triple agonist at the GIP, GLP-1 and glucagon receptors, with a fatty-acid moiety that extends its half-life in circulation.
It is used in metabolic research as a reference standard for incretin receptor assays, receptor-binding comparisons against dual agonists, and analytical method development.
This listing is the 5mg presentation of Retatrutide. Each lot is assayed by reverse-phase HPLC to ≥99% and confirmed by LC-MS against the expected mass. Vials ship sealed and desiccated, are stable at ambient temperature in transit, and should be stored at −20 °C on arrival. Reconstituted material is kept refrigerated and used within the window defined by your own protocol. Orders placed before the daily cut-off are typically dispatched within 24 hours from the UK, with tracked delivery across the UK and the European Economic Area.
- What purity is Retatrutide tested to?
- Every lot of Retatrutide is assayed by reverse-phase HPLC to ≥99% and identity-confirmed by LC-MS. The result printed on your certificate is the result for the lot number on your vial, never a generic or representative figure.
- Does Retatrutide come with a certificate of analysis?
- Yes. A lot-specific certificate of analysis is issued with every vial, showing the HPLC purity trace, mass-spectrometry identity confirmation and the lot number. Analysis is carried out by an independent partner laboratory.
- How should Retatrutide be stored?
- Store the sealed, lyophilised vial at −20 °C and keep it desiccated. The powder is stable at ambient temperature during transit. Once reconstituted, material is refrigerated and used within the timeframe your protocol specifies.
- Do you ship Retatrutide to the UK and Europe?
- Yes. Orders are dispatched from the UK, typically within 24 hours of payment clearing, with tracked delivery to the United Kingdom and to the European Economic Area countries we currently serve. UK pricing is in pounds sterling and EU pricing is in euros.
- Is Retatrutide suitable for human or veterinary use?
- No. Retatrutide is an unlicensed reference standard supplied strictly for in-vitro laboratory research by qualified professionals. It is not a medicine, dietary supplement or cosmetic, and must not be administered to humans or animals.
