Retatrutide is supplied by Aegis Bio as lyophilised powder in 8 specifications, for in-vitro laboratory research use only. Composition for the lot supplied is stated on its certificate of analysis.
Supplied against a ≥99% HPLC purity specification. Lots are analysed by Janoshik Analytical, an independent laboratory commissioned by the manufacturer, and Aegis Bio submits selected lots to Accumark in California for its own independent verification. The figure measured for the lot supplied is stated on its certificate of analysis, available by request before ordering. What each section of a COA establishes.

Choosing a specification
Retatrutide is listed in 8 specifications. Measured by cost per milligram — the only figure that compares cleanly across different strengths and vial counts — the best value is the 60 mg x 10 vials at $280.00, which works out to $0.467/mg. The least efficient listing is the 20 mg x 1 vial at $45.00, or $2.250/mg — a 4.8× premium per milligram.
The single 20 mg x 1 vial vial at $45.00 exists to evaluate the material before committing to pack quantities; the 60 mg x 10 vials pack brings the rate down to $0.467/mg. Whether that premium is worth paying depends on whether you will consume pack quantities within the material's useful life — unused material is not cheap material. Single vials also ship at the reduced $20.00 rate when ordered alone, and ride along free inside any order containing a pack.
Reconstitution reference
Resulting concentration by vial strength and diluent volume. Arithmetic only, provided for laboratory preparation and dilution planning — this is not dosing guidance. The method is set out in the reconstitution and dilution guide.
| Vial | +1 mL | +2 mL | +3 mL | +5 mL |
|---|---|---|---|---|
| 5 mg | 5.00 mg/mL | 2.50 mg/mL | 1.67 mg/mL | 1.00 mg/mL |
| 10 mg | 10.00 mg/mL | 5.00 mg/mL | 3.33 mg/mL | 2.00 mg/mL |
| 20 mg | 20.00 mg/mL | 10.00 mg/mL | 6.67 mg/mL | 4.00 mg/mL |
| 30 mg | 30.00 mg/mL | 15.00 mg/mL | 10.00 mg/mL | 6.00 mg/mL |
| 40 mg | 40.00 mg/mL | 20.00 mg/mL | 13.33 mg/mL | 8.00 mg/mL |
| 50 mg | 50.00 mg/mL | 25.00 mg/mL | 16.67 mg/mL | 10.00 mg/mL |
| 60 mg | 60.00 mg/mL | 30.00 mg/mL | 20.00 mg/mL | 12.00 mg/mL |
Composition and identity
Retatrutide does not currently resolve to a single unambiguous PubChem record, so computed descriptors are not reproduced here rather than being estimated. Identity and content for a material of this kind are established from the certificate of analysis for the lot supplied — the component list, the ratio and the measured purity of each — rather than from a reference structure. Request the COA for the specific lot before ordering if your protocol depends on the composition. A 60 mg vial reconstituted with 2 mL yields a combined concentration of 30.0 mg/mL across all components; the ratio between components in solution is fixed by the fill and cannot be adjusted.

How this compares within its class
By best available cost per milligram it ranks 3 of 7 in Metabolic & Incretin, against a class range of $0.367 to $3.300 per mg. It is listed in 8 specifications, against a class median of 2.

Storage and handling
Incretin-class analogues are long-chain acylated peptides and are among the highest-molecular-weight materials in this catalog. They are typically supplied at higher fill masses per vial, which means a single reconstitution produces a large working volume — aliquoting is worth planning before the first entry rather than after.
- Lyophilised powder: store sealed at −20 °C, protected from light and moisture.
- Bring sealed vials to room temperature before opening, so warm air does not condense moisture onto cold powder.
- Reconstitute with bacteriostatic water directed against the vial wall; do not shake or vortex. Swirl gently until dissolved.
- After reconstitution: store at 2–8 °C and use within the working period established by your laboratory.
- Avoid repeated freeze–thaw cycles. Aliquot where the solution will be accessed repeatedly.

Documentation
A certificate of analysis is available by request for the batch supplied, covering HPLC purity and mass-spectrometry identity confirmation. The two measurements answer different questions — identity confirms the molecule, purity quantifies how much of the sample it represents. See what each one proves.
Frequently asked
What specifications of Retatrutide are available?
Retatrutide is listed in 8 specifications: 20 mg x 1 vial, 5 mg x 10 vials, 10 mg x 10 vials, 20 mg x 10 vials, 30 mg x 10 vials, 40 mg x 10 vials, 50 mg x 10 vials, 60 mg x 10 vials. Prices are in USD and include the vial.
Is a certificate of analysis available for Retatrutide?
Yes. A certificate of analysis is available by request for the batch supplied, covering HPLC purity and mass-spectrometry identity confirmation. Request the COA for a specific lot before ordering if your protocol requires documentation on file.
Why do incretin-class vials produce such large working volumes?
These analogues are supplied at higher fill masses per vial than most research peptides, so a standard reconstitution volume yields a large quantity of solution. Plan the diluent volume for the concentration you need and aliquot before the solution begins to age, rather than repeatedly entering one vial.
How should Retatrutide be stored?
Store the lyophilised powder sealed at −20 °C, protected from light and moisture. After reconstitution, store at 2–8 °C and avoid repeated freeze–thaw cycles. Bring sealed vials to room temperature before opening to avoid condensation onto cold powder.
What does shipping cost?
Carts made up entirely of single vials ship for $20.00. Any cart containing a multi-vial kit ships for $60.00 standard or $80.00 expedited, with single vials included free. From 4 kits upward the rate drops to $30.00 standard or $50.00 expedited. Shipping is added at checkout and revalidated on the server before the order is accepted.
How is payment handled?
Payment is accepted in on-chain Bitcoin or USDT on Ethereum (ERC-20). No card details are collected. Orders remain pending until the payment is verified on-chain, after which a confirmation is sent.
