Research Overview
BPC-157 has been studied mainly in rodent and cell-culture models of tendon, ligament and gastrointestinal tissue, where researchers have examined its interaction with growth-factor signalling, angiogenesis and nitric-oxide pathways.
It is one of the most widely cited research peptides in the tissue-repair literature, and recent reviews summarise both the preclinical findings and the open questions that remain.

BPC-157: Research Background
BPC-157 is a 15-residue partial sequence of a larger protein, termed body protection compound, that was described in gastric juice. Most of the published work comes from Predrag Sikiric’s group at the University of Zagreb.
Rodent and cell-culture studies have examined BPC-157 in tendon, ligament and gastrointestinal tissue models. Mechanistic papers describe interactions with the VEGFR2–Akt–eNOS pathway, nitric-oxide signalling, and FAK–paxillin signalling in tendon fibroblasts.
Reviews highlight that most data are preclinical, and they list open questions about mechanism and reproducibility, which continue to drive laboratory research.
What the BPC-157 COA Confirms
OxygenLab products are tested by independent third-party laboratories. HPLC reports purity as the main peak’s share of total peak area, and mass spectrometry confirms identity against the expected molecular weight of 1419.5 g/mol. Published certificates are on our COA page, and others are available on request; match the lot number on your vial to the report before use in an experiment.

More Questions About BPC-157
How many amino acids are in BPC-157?
Fifteen: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val.
Why are there 5 mg and 10 mg BPC-157 vials?
The compound and testing are identical; the two sizes suit different laboratory batch sizes.
Storage and Handling
- Store lyophilized powder at -20°C for long-term storage, protected from light and moisture.
- Short-term storage at 2–8°C is acceptable for unopened vials.
- Allow the vial to reach room temperature before opening to limit moisture uptake.
- Record batch and lot numbers for every preparation.
