How Long Does BPC-157 Last? Shelf Life & Stability
"Stable" is meaningless without saying stable against what. BPC-157 has its own set of degradation routes, and they determine which storage precautions actually matter for it.
In plain English
Unusually tough. Because it was found in stomach fluid, it resists the kind of breakdown that destroys most peptides quickly. Worth being precise though: surviving stomach acid is not the same as lasting forever in a vial. Once mixed, three to four weeks refrigerated is the realistic window.
What BPC-157 actually is
BPC-157 is a short chain of fifteen amino acids originally identified in stomach fluid — an environment whose whole chemical job is to break proteins apart. It got attention precisely because it survived that. In research it is studied around how new blood vessels form and how repair signals travel through tissue.

Degradation routes specific to BPC-157
- Aspartate isomerisation — the Asp-Ala pairs at positions 10–12 are the most plausible slow degradation route in solution over long storage.
- Microbial growth in non-preserved diluent, which is a container problem rather than a molecular one.
- Adsorption losses to plastic at very low working concentrations.
Its gastric-fluid stability is frequently over-generalised. Resistance to acidic proteolysis is not the same as indefinite solution stability at room temperature — treat the two claims separately.
Freeze–thaw tolerance
Tolerates freeze–thaw better than most peptides in this catalogue, but repeated cycles still concentrate solutes at the ice interface. Aliquot on first reconstitution rather than relying on that tolerance.
How storage addresses these routes
Practical window once reconstituted: 3–4 weeks at 2–8 °C in bacteriostatic water.
