BPC-157 is the 15-residue peptide most labs reach for in tendon, gut and vascular repair models, which is exactly why weak batches get sold under its name. Titan Core lists its full sequence and weight and ties each vial's LOT to a third-party purity report you can check.

The BPC-157 peptide is a synthetic 15-amino-acid fragment of a protein found in gastric juice, and labs use it to study repair signaling in tendon, gut and blood-vessel models. Its mechanism is getting sharper: a 2026 study in Cell Communication and Signaling found BPC-157 binds the adaptor protein FBXO22 through the proline at position 3, stabilizing the transcription factor BACH1 and boosting endothelial tube formation.
That precision is why impurities matter. At its July 2026 advisory meeting, the FDA described BPC-157 acetate as not well characterized, citing missing data on impurities, aggregates, bioburden and endotoxin. A chain missing one of its four prolines weighs 97 Da less and can sit under a vague purity claim. The competitor reports we read list purity, endotoxin and milligrams, but none gives an aggregate result and one runs no mass test. Titan Core's BPC-157 is third-party tested to 99%+ HPLC purity, its sequence and 1,419.6 Da weight are listed below, and each vial's LOT ties to its lab report; if yours isn't posted yet, ask Contact Support before opening. Research reagent only; never for human or animal use.
Research Highlights
Short for Body Protection Compound 157, a stable pentadecapeptide first described from gastric juice. It carried the development code PL 14736.
It's studied in tendon, gut, vascular and kidney-injury models, mostly in rats, where researchers track angiogenesis and nitric-oxide signaling.
Fifteen, with a proline-rich start: glycine, glutamate, three prolines, glycine, lysine, proline, alanine, two aspartates, alanine, glycine, leucine and valine.
Use the single peptide when its effect has to be isolated. Blends pair it with TB-500, GHK-Cu or KPV for multi-pathway designs.
You can buy BPC-157 peptide here, with its sequence and weight spelled out. If it shows out of stock, Contact Support can put you on notice for the next LOT.
It has no FDA approval, and the agency's 2026 review flagged gaps in its characterization data. Titan Core sells it as a laboratory reagent and gives no advice on side effects, dosing or use in people.
Match the LOT, then read HPLC purity and an identity mass near 1,419.6 Da; a hit about 97 Da low points to a missing proline. If the LOTs differ, leave the vial sealed and send photos to support within 48 hours of delivery.
