What you are buying
Each vial contains the stated mass of retatrutide as a lyophilised cake, sealed under a crimp cap. The label carries the lot number that matches the certificate of analysis. Peptide content (how much of the powder is peptide, as opposed to counter-ion and residual water) is reported on the COA alongside purity; see reading a certificate of analysis for how to compare the two figures.

How to check a retatrutide supplier
- Batch-specific COA from a named laboratory, with the chromatogram, not a purity number alone.
- Lyophilised powder rather than pre-mixed solution.
- Lot number on the vial that matches the certificate.
- Clear research-use-only terms and no medical claims.
- Domestic shipping and a contact channel a person answers.
Aegis Bio publishes its documentation process on the certificates of analysis page and answers on WhatsApp. The broader checklist is in where to buy research peptides.
Storage
Keep lyophilised vials at −20 °C. Reconstituted solution is held at 2–8 °C and used within days. Avoid repeated freeze-thaw, and aliquot if a lot will be drawn from over time — see storing lyophilised research peptides.
