How to Store CJC-1295: Refrigeration and Shelf Life

Whether CJC-1295 needs refrigeration, how long powder and mixed vials keep, and what to do if a vial got warm.

Medically reviewed by Juan Pablo Frías, MD · · DisclosureGHRH analogUpdated

For the FDA-approved product, the label and package insert are the authority on storage. The notes below are for vials of powder that are mixed before use.

Storage at a glance

No published stability study or label storage data for CJC-1295 was found (PubMed search, 2 Oct 2026). We add storage conditions only from a manufacturer label or a stability study.

Unmixed powder

Freeze-dried (lyophilized) powder is the form most vials ship in. Storage temperature and shelf life for CJC-1295 powder: not published in any source we found.

  • Keep vials sealed, dry and out of direct light and heat until use.
  • Check the label for a lot number and an expiry date. A vial with neither tells you nothing about its age.

After mixing

Once mixed with bacteriostatic water, peptide vials are usually kept in the refrigerator and used within a limited time. The verified window for CJC-1295: not published in any source we found.

  • Write the mixing date on the vial.
  • Swab the rubber top with alcohol before every draw.
  • Do not freeze a mixed vial unless the product information says you can.

If it got warm or looks wrong

Do not use a vial that: looks cloudy, has particles or has changed colour (unless the product information says that is expected), or has a damaged seal.

How much potency CJC-1295 loses after a temperature slip is not covered by any published stability study we found. When in doubt, ask a pharmacist.

Common questions

Does CJC-1295 need to be refrigerated?

Follow the storage instructions on the approved product's label. Compounded or research versions should come with their own instructions; if they don't, ask the pharmacy.

How long is CJC-1295 good for after mixing?

That depends on the product and how it was mixed. We publish a shelf life only from a manufacturer or a stability study, and we found none for CJC-1295 (PubMed search, 2 Oct 2026).
