Retatrutide (R3TA) ships as a lyophilised (freeze-dried) powder. This guide covers standard laboratory handling for research use only.
Reconstitution
For research handling, lyophilised peptide is typically reconstituted with bacteriostatic water, added slowly against the vial wall rather than directly onto the powder, then left to dissolve without shaking. Do not consume — this is a laboratory procedure only.
Storage & stability
- Lyophilised (unopened): stored cool and dark; stable long-term when kept sealed.
- Reconstituted: refrigerated (2–8°C), protected from light, and used within the window supported by the batch data.
- Avoid repeated freeze–thaw cycles, which can degrade peptide integrity.
Verify the batch first
Before any handling, confirm the batch Certificate of Analysis for identity and purity.
For research use only. Not for human or animal consumption. Sold to qualified researchers, 18+.
Frequently asked questions
How is retatrutide reconstituted for research?
For research handling, the lyophilised powder is reconstituted with bacteriostatic water added slowly against the vial wall and allowed to dissolve without shaking. It is a laboratory procedure only and not for human use.
How should retatrutide be stored?
Unopened lyophilised vials are kept cool and dark. Once reconstituted, store refrigerated at 2-8C, protected from light, and avoid repeated freeze-thaw cycles.
Where can I get bacteriostatic water?
Vero Labs supplies bacteriostatic water alongside R3TA for research handling. All products are for research use only.
