BPC-157

What Is BPC-157?

BPC-157 (“Body Protection Compound 157”) is a synthetic pentadecapeptide — a 15-amino-acid sequence originally isolated as a fragment of a protein found in gastric juice. It is supplied by CertaPeptides as a pharmaceutical-grade lyophilized powder for in vitro and preclinical research use.

CAS: 137525-51-0. Sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val.

• Chang et al. (2014) reported that, in cultured rat Achilles tendon fibroblasts, BPC-157 exposure was associated with increased growth hormone receptor expression compared to control. Source: Molecules, 19(11), 19066–19077. PMID 25415472.
• Krivic et al. (2008) observed, in a rat Achilles tendon-to-bone transection model, differences in early functional recovery measurements between BPC-157-treated animals and controls. Source: Inflammation Research, 57(5), 205–210. PMID 18594781.
• Staresinic et al. (2006) reported outcome measurements after application of BPC-157 in a rat transected-quadriceps model. Source: Journal of Orthopaedic Research, 24(5), 1109–1117. PMID 16609979.

Research Areas Where BPC-157 Is Studied

• Preclinical models of musculoskeletal tissue response (rodent tendon, ligament, muscle)
• In vitro fibroblast and endothelial cell culture assays
• Experimental gastrointestinal mucosa models in rats and mice
• Nitric-oxide pathway signalling studies in animal tissue

Within the Tissue-Repair Cluster — How BPC-157 Differs

BPC-157 is studied alongside two other research peptides in overlapping tissue-repair contexts: TB-500 (a 17-amino-acid fragment of thymosin β-4) and the combined BPC-157 + TB-500 blend. These compounds come from different biological origins and modulate different molecular pathways, which is why researchers often use them in combination rather than as substitutes:

BPC-157’s distinguishing research angle is its gastric origin and mucosal-protection phenotype: it is the only compound in this cluster with published preclinical evidence in GI mucosa models, and the only one routinely studied under oral administration. For researchers investigating combined actin-cytoskeletal + nitric-oxide pathways in the same protocol, the BPC-157 + TB-500 blend presents a fixed 1:1 formulation; for independent dose control or single-pathway studies, the individual products are preferred. Researchers comparing the two frequently reference the TB-500 vs BPC-157 comparison, the blend-vs-individual decision guide, and the ultimate guide to BPC-157 research.
