What Is BPC-157?
One of the most studied peptides in tissue-repair research — and half of the well-known "BPC + TB" pairing. Here's what it is and how it's handled.
BPC-157 is one of the best-known names in tissue-repair research — and if you've seen it mentioned, it was probably alongside TB-500. The two come up together so often that they're frequently studied (and sold) as a pair.

What is BPC-157?
BPC-157 stands for "Body Protection Compound-157." It's a synthetic peptide made of 15 amino acids — a stable fragment related to a protein naturally found in gastric (stomach) juice. It's supplied to researchers as a lyophilized powder and is studied in models of tissue repair.
What is it studied for?
In the research literature, BPC-157 is most associated with tissue-repair and healing pathways — work in laboratory and animal models has looked at things like angiogenesis (the formation of new blood vessels) and the repair of connective tissue such as tendon and ligament. It's important to be clear: this is research-model context, not a statement about outcomes in people.
BPC-157 and TB-500 are studied for complementary repair pathways — which is why they're so often paired.
Why BPC-157 is paired with TB-500
The two are frequently studied together — and often sold as a blend — because they're investigated for complementary tissue-repair mechanisms. They're still two distinct compounds, each with its own profile. If you're looking at the pair, see our TB-500 guide for the other half.
How is BPC-157 handled in the lab?
- Keep the sealed vial cool, dry, and out of direct light.
- Reconstitute with bacteriostatic water — see how to reconstitute peptides and how much BAC water to use.
- Refrigerate the reconstituted solution, where it stays stable for weeks.
Why purity matters
Confirm what's in the vial. A reputable source includes a Certificate of Analysis (COA) with third-party HPLC purity and mass-spec identity for that batch — here's how to read one.

Frequently asked questions
What is BPC-157?
A synthetic peptide of 15 amino acids, a stable fragment related to a protein found in gastric juice. Studied in tissue-repair research and supplied as a lyophilized powder for research use only.
Why are BPC-157 and TB-500 used together?
They're often studied as a pair (sometimes sold as a blend) because they're investigated for complementary tissue-repair pathways. Each is its own distinct compound.
How is it stored and prepared?
It ships as a freeze-dried powder, kept cool and dry, and is reconstituted with bacteriostatic water before use. After reconstitution it's refrigerated.
Is BPC-157 sold for human use?
Material sold for research is supplied and handled for research use only, not for human use.
