In Plain English
Simple summaryBPC-157 has been studied at the University of Zagreb for over three decades, and it keeps turning up in the same places: wherever tissue is trying to heal. It's a 15-amino acid peptide derived from a protective protein found in human gastric juice -- your stomach naturally produces a tiny amount of it. What stands out in the research is how broad it is. Most healing compounds specialize. BPC-157 keeps appearing in tendon, gut, nerve, and even cardiovascular studies. The honest caveat: virtually all the evidence comes from rodent models, and no completed human clinical trial exists yet.

What is BPC-157?
Tap any underlined term for an instant definition.
BPC-157 (Body Protection Compound-157) is a pentadecapeptide composed of 15 amino acids, originally derived from a protective protein found in human gastric juice. It has been extensively studied for its extraordinary healing and regenerative effects across a wide range of tissues including tendons, ligaments, muscles, the gut lining, and the nervous system. BPC-157 is thought to work primarily by upregulating growth hormone receptors and modulating nitric oxide production, promoting angiogenesis (new blood vessel formation) and accelerating tissue repair. Research has consistently shown it to be safe and non-toxic with no known LD50.

Common Stacks
BPC-157 is frequently combined with the following peptides for synergistic effects. Click any peptide to compare profiles before deciding.
The most popular healing stack - BPC-157 handles acute repair while TB-500 promotes systemic tissue remodeling and angiogenesis.
BPC-157 drives mucosal healing while KPV directly suppresses NF-kB inflammation - together they cover both healing and anti-inflammatory dimensions of gut repair.
Often added to support GH-driven recovery, as Ipamorelin amplifies the regenerative signaling BPC-157 initiates.
KPV's anti-cytokine action pairs with BPC-157's angiogenic healing for a comprehensive gut and systemic inflammation protocol.

Dosing Data from the Literature
Doses referenced below are sourced from published preclinical and clinical studies. Use the peptide dose calculator to convert these values to injection volume.
Typical research dosing: 250–500 mcg per day. For systemic effects, subcutaneous or intramuscular injection is preferred. For localized healing (e.g., tendon), injecting near the injury site is recommended. Oral administration (500–1000 mcg) can be effective for gut-related issues.
Administration in Research Settings
Standard reconstitution and administration methodology for laboratory research use.
BPC-157 is typically reconstituted with bacteriostatic water and administered via subcutaneous injection. For localized injuries, inject as close to the injury site as possible (proximal injection). For systemic or gut effects, subcutaneous injection in the abdomen is preferred. Some protocols use oral administration for gut healing. Cycle on for 4–6 weeks, then take a break of equal length.
What the research doesn't show
Every published study uses animal models. Human dosing is extrapolated from rodent data -- no dose-response data in humans exists yet. The lack of human trials is a real gap, not just a technicality.

How It Compares
TB-500 (thymosin beta-4) is the other popular tissue repair peptide. The practical difference is target: BPC-157 has stronger evidence for tendons, gut, and nerves; TB-500 is more studied for skeletal muscle and cardiac tissue. Many protocols run them together for 4–8 weeks during active injury recovery.
