Buy Retatrutide (RUO): specifications, purity, storage and 2026 pricing

Where to buy retatrutide for in-vitro research in the US: sizes from a 10 mg single vial, 99% HPLC purity with a COA per lot, storage, shipping and pricing.

Retatrutide is available from Aegis Bio as a research-use-only lyophilised peptide, from a 10 mg single vial at $25 to 10-vial kits up to 60 mg, with a certificate of analysis for every lot and US shipping at $20 for single vials or $45 with a kit.

Key facts

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

  1. Batch-specific COA from a named laboratory, with the chromatogram, not a purity number alone.
  2. Lyophilised powder rather than pre-mixed solution.
  3. Lot number on the vial that matches the certificate.
  4. Clear research-use-only terms and no medical claims.
  5. 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.

Ordering and shipping

Orders are placed on the retatrutide page. Payment is on-chain Bitcoin or USDT (ERC-20); orders remain pending until payment is verified, then ship from the United States. Shipping is $20 for a cart of single vials and $45 when a kit is included. All sales are final. WELCOME10 takes 10% off the items subtotal of a first order.

All materials are supplied for in-vitro laboratory research use only. Nothing on this page is a therapeutic claim, and no dosing guidance is provided.
