BPC-157 — compound background
Synthetic pentadecapeptide (15 residues), acetate salt
BPC-157 is a 15-amino-acid sequence (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) isolated from a larger protein found in human gastric juice. Its provenance is the reason for one of its most-cited laboratory properties: it was characterised as remaining intact in gastric-fluid conditions that rapidly hydrolyse most peptides.
Solubility & reconstitution
Freely water-soluble and among the most forgiving peptides in this catalogue to reconstitute. The high proline content (five of fifteen residues) gives an extended, largely unstructured conformation with no hydrophobic core to drive aggregation, so it dissolves without acidification, sonication, or warming. Solutions are clear and colourless — persistent cloudiness indicates a handling problem, not a solubility limit.
Commonly worked at 1–5 mg/mL; higher concentrations remain clear but offer no handling advantage.
Storage
Unusually tolerant for a peptide. Sealed lyophilized powder is stable at -20 °C long-term, and the compound is well documented as surviving ambient excursions during transit far better than most sequences of comparable length. Refrigerate at 2–8 °C. The proline-rich backbone lacks the oxidation-prone residues (Met, Cys, Trp) that shorten the working window of other research peptides.
Commonly worked with for 3–4 weeks at 2–8 °C in bacteriostatic water.
Stability
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.
Reading the Certificate of Analysis
Confirm the observed mass matches 1419.5 Da for the free peptide. Because BPC-157 is supplied as an acetate salt, net peptide content can sit meaningfully below the gross vial mass — check whether the COA reports peptide content separately from purity, since a 99% pure vial is not the same as a vial that is 99% peptide by weight.
