RCT, meeting abstract2005
The only randomized, double-blind, placebo-controlled trial FDA identified, a 2005 meeting abstract, gave 53 patients with mild-to-moderate ulcerative colitis a BPC-157 (PL 14736) enema or placebo for two weeks; the Disease Activity Index fell 3.2 vs 1.6 points, a difference that was not statistically significant, and FDA judged the data inadequate to support efficacy or safety.

review of pilot studies2026
A 2026 review of regenerative peptides for pain concluded that human evidence for BPC-157 is limited to small pilot studies (musculoskeletal pain, interstitial cystitis and intravenous use) and that comprehensive controlled trials are still needed before clinical use.

retrospective chart review2021
A retrospective chart review at one clinic reported that 14 of 16 patients given knee injections of BPC-157 (alone or with thymosin beta-4) described symptom relief, including 11 of 12 given BPC-157 alone; with no control group, the design cannot show that BPC-157 caused the relief.

literature review2025
A 2025 literature and patent review noted that BPC-157 has not been approved by FDA or other regulators because comprehensive human clinical studies are lacking; the effects it describes come from preclinical models of tissue injury, inflammatory bowel disease and central nervous system disorders.

review of rodent studies2019
A 2019 review of musculoskeletal soft-tissue healing noted that efficacy in humans is unconfirmed and that only a handful of research groups have published in-depth studies; in rodent injury models, BPC-157 consistently sped tendon, ligament and skeletal-muscle healing.
