Research HubBPC-157
Clinical — 10 studies
BPC-157 is a synthetic peptide derived from a fragment of human gastric juice that has been widely investigated in preclinical research models for tissue repair and cytoprotective effects.
Being studied for
- Tendon and ligament healing
- Gastrointestinal tissue protection
- Angiogenesis and wound repair
Published Research
Evidence profile
Preclinical, with limited uncontrolled human reports
10 cited publications
Evidence gap: No controlled human trial was identified. The human reports are small, uncontrolled pilots in single clinical settings; the remaining evidence is animal and in-vitro.
Findings below belong to the studies that reported them. They describe the material and conditions those authors used, not this product, and not an outcome to expect.
Core evidence
The publications most central to understanding this compound.
Injectable Peptide Therapy: A Primer for Orthopaedic and Sports Medicine Physicians
Mayfield CK et al. · The American journal of sports medicine · 2026
A review of injectable peptide therapy written for orthopaedic and sports medicine practitioners, which examines the evidence base behind BPC-157 and related peptides and characterises how far it supports clinical use.
“While peptide therapy may possess significant therapeutic and regenerative potential, it is critical that orthopaedic and sports medicine providers understand the current lack of evidence to support the clinical use of these peptides.”
Context: A review, not new evidence. It is featured because it describes the size and quality of the evidence base.
From Regeneration to Analgesia: The Role of BPC-157 in Tissue Repair and Pain Management
Yuan C et al. · International journal of molecular sciences · 2026
Reviews the published BPC-157 literature across tissue repair and pain models, covering reported mechanisms alongside preparation standards, clinical validation and regulatory constraints.
“BPC-157 remains a promising candidate for regenerative medicine, yet comprehensive evaluation is required before clinical translation can be recommended.”
Context: Reviews a largely preclinical literature and adds no human data.
Supporting evidence
Effect of BPC-157 on Symptoms in Patients with Interstitial Cystitis: A Pilot Study
Lee E et al. · Alternative therapies in health and medicine · 2024
Population: Patients with moderate to severe interstitial cystitis not responding to pentosan polysulfate
A small uncontrolled pilot administering BPC-157 into the bladder and reporting symptom change. One of very few human reports involving this compound.
Context: A pilot with no control arm and few participants, in one clinical context. It cannot establish an effect and does not generalise.
Protective effects of BPC 157 in rats with experimentally induced lower extremity ischemia-reperfusion injury
Yıldırım AK et al. · Scientific reports · 2026
Population: Rat model of lower-limb ischaemia-reperfusion injury
An animal study measuring oxidative stress, apoptosis, inflammation and angiogenesis markers in skeletal muscle after induced ischaemia-reperfusion injury.
Context: A rodent model. The findings describe that model and do not transfer to humans.
