Peptide Storage Cheat Sheet
Simple storage guidance for research peptides before and after mixing, including dry powder storage, reconstituted peptide storage, BAC water handling and signs a vial may have degraded.
Unreconstituted Peptides

Per-Compound Notes
General community storage notes
Semaglutide / TirzepatideGenerally discussed as stable refrigerated
BPC-157Commonly discussed around 4 weeks mixed
TB-500May appear slightly cloudy in some cases
Semax / SelankOften discussed as more fragile
IGF-1 LR3Often treated as more sensitive
EpithalonGenerally discussed as stable dry
Core Storage Rule
Dry powder is usually stored cold and protected from light. Once mixed, research peptides are generally kept refrigerated, protected from light and not frozen. Always label vials with the compound name and date mixed.
Simple Peptide Storage Checklist
Before mixing
- Check the vial label and supplier instructions.
- Keep dry powder cold and away from light.
- Avoid repeated freeze-thaw cycles.
- Do not use damaged, leaking or unclear vials.
After mixing
- Label the vial with the date reconstituted.
- Store refrigerated at 2–8°C.
- Keep the vial protected from light.
- Discard if the solution looks, smells or behaves unusually.
