BPC-157
BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in gastric juice. It is studied for tendon, ligament, muscle and gut tissue repair, and for anti-inflammatory and neuroprotective activity. It is not approved for human use.

What the research reports
Reported benefits of BPC-157
Outcomes described across the published BPC-157 literature and ongoing study. Read each as research context rather than a promised personal result.
- 01
Soft tissue and tendon repair
Studied for tendon, ligament and muscle healing, with animal models reporting faster fibroblast outgrowth after induced injury. Reported in research settings.
- 02
Gut and gastric lining support
Originally isolated from gastric juice and studied in models of ulceration, colitis and chemically induced intestinal damage. Reported in research settings.
- 03
Angiogenesis and blood flow
Animal models report promotion of new blood vessel formation and collateral circulation, helping nutrients reach injured tissue faster during healing.
- 04
Anti-inflammatory signalling
Preclinical studies describe reduced inflammatory markers and lower oxidative stress in injured tissue, alongside modulation of nitric oxide pathways.
- 05
Post-injury recovery research
Case series in knee pain and interstitial cystitis reported symptom improvement, although none of the human work published to date was randomised or placebo controlled.
Dosage and protocol
How BPC-157 is typically studied
Research protocols use 200 to 500 mcg daily by subcutaneous or intramuscular injection, running 4 to 12 weeks. Half-life is 4 to 6 hours and it is frequently stacked with TB-500.
- Route
- Subcutaneous injection
- Example range
- 250-500 mcg
- Frequency
- Once or twice daily
- Timing
- Inject near injury site for local effect, or abdomen for systemic.
Clinical evidence
BPC-157 clinical evidence summary
The published BPC-157 record, labeled by strength so you can see what is settled and what is still emerging.
Interstitial cystitis pilot
A 2024 pilot case series of 12 patients found a single 10 mg intravesical injection resolved interstitial cystitis symptoms in 10 of them with no adverse events.
SourceIntravenous safety pilot 2025
A 2025 pilot in two healthy adults reported that intravenous infusion up to 20 mg over three days was tolerated with no adverse effects recorded by the authors.
SourceInteractions
How BPC-157 pairs with other peptides
- TB-500 peptide
- Synergistic for tissue repair. BPC-157 drives angiogenesis while TB-500 modulates actin and cell migration.
- GHK-Cu peptide
- Synergistic for tissue remodelling. Both support wound healing through separate biological mechanisms.
- Semaglutide
- No known negative interaction. May support gut comfort during GLP-1 therapy through a different mechanism.
- Ipamorelin
- No known negative interaction. Different primary targets, and the two are often combined in clinic settings.
Questions
Frequently asked questions.
What is BPC-157?
BPC-157 is a peptide compound used in research settings. It is commonly studied for its role in healing, tissue repair, and many researchers compare supplier quality, purity, and testing data before purchasing.
What are the research benefits of BPC-157?
BPC-157 is often evaluated for its potential influence on signaling pathways, recovery support, and targeted research applications. Research interest varies by peptide, formulation, and study design, so buyers typically review purity, dose, and independent lab verification before choosing a source.
How does BPC-157 work?
Like other research peptides, BPC-157 is typically studied for how it interacts with specific biological pathways and receptor systems. In practice, the way it is formulated, dosed, and tested matters as much as the compound itself, which is why verified suppliers and transparent COAs are important.
Is BPC-157 for research use only?
Yes, products like BPC-157 are generally intended for research, laboratory, or educational use and are not marketed as approved human therapeutics. Always follow local laws, lab safety practices, and institutional requirements before handling or studying any peptide.
What should I look for before buying BPC-157?
Key checks include verified COA data, peptide form and concentration, supplier reputation, stock status, and cost per mg. Comparing pricing and testing records side-by-side helps reduce the risk of buying an under-tested or misrepresented product.
