BPC-157 Clinical Trials and Human Studies

Human research on BPC-157 remains limited. Three full human reports have been published in recent years, while earlier placebo-controlled studies were reported only in conference abstracts. Four additional BPC-157 interventional studies are currently registered on ClinicalTrials.gov, including a recruiting Phase 2 hamstring-strain trial. No full peer-reviewed randomised controlled efficacy trial has yet established that BPC-157 works in humans.

What Human Studies Have Been Published on BPC-157?

Three full human reports have been published, all since 2021: a retrospective study of intra-articular BPC-157 for knee pain (17 patients reviewed),1 a pilot of BPC-157 injections in 12 women with interstitial cystitis,2 and a two-person intravenous safety pilot.3 None had a placebo or untreated comparison group.

Earlier BPC-157 human trials reported only as abstracts

The US Food and Drug Administration's 2026 evidence review of BPC-157 identified earlier human studies from the 2000s that were reported only as conference abstracts.8 A placebo-controlled Phase I safety study gave BPC-157 by rectal enema to 24 healthy volunteers in 2002–03. A multicentre, randomised, double-blind, placebo-controlled trial in 2005 randomised 53 people with mild-to-moderate ulcerative colitis to a BPC-157 enema or placebo for two weeks; 46 completed the trial, and the reported results could not show a clear difference between BPC-157 and placebo.

Full peer-reviewed details of these studies are not publicly available, so their findings cannot be assessed to the same standard as a complete published paper. The FDA's review concluded the available data were inadequate to support the efficacy and safety of BPC-157.8

Controlled BPC-157 trials have taken place. The evidence from them, however, is limited to conference abstracts, and no complete, peer-reviewed record of a controlled efficacy trial has been published.

What BPC-157 Clinical Trials Have Been Registered?

Four interventional BPC-157 studies are currently listed on ClinicalTrials.gov.4,5,6,7 Two carry the most weight: a Phase I oral safety and pharmacokinetics study registered in 2015 with no publicly posted results, and a Phase 2 placebo-controlled study of acute hamstring strain that began recruiting in 2026.

The sponsor, PharmaCotherapia d.o.o., registered a randomised, placebo-controlled and fully blinded study of an oral formulation called PCO-02, whose active ingredient is BPC-157 (also designated Bepecin). The trial planned to enrol 42 healthy adults aged 18–35, in single- and repeated-dose stages, with safety as its main focus and pharmacokinetics alongside. It was listed as starting in October 2015 with an estimated completion of March 2016. The registry entry was last updated in December 2015; its overall status is recorded as unknown, with a last known status of active, not recruiting, and no results have been publicly posted.

The sponsor, Hudson Biotech, is running a randomised, placebo-controlled and fully blinded Phase 2 trial in which participants receive BPC-157 or placebo by injection alongside the same standardised rehabilitation programme. It measures two main outcomes: how quickly participants return to unrestricted sport, and the change in injury size on MRI scans, assessed by radiologists who do not know which treatment each participant received. The trial began in February 2026, is recruiting in Shenzhen, China, and lists an estimated completion of February 2028.

Registration does not mean successful completion, publication or demonstrated efficacy. A registry record tells us a trial was planned and what it set out to measure; without posted results, its outcome cannot be known.

What Does the Human Evidence Actually Tell Us?

The level of conclusion each kind of evidence can support.

Has BPC-157 been used in published human research?

Yes

Three full published reports describe human exposure to BPC-157: a retrospective knee-pain study, a 12-person interstitial cystitis pilot and a two-person intravenous safety pilot. Earlier placebo-controlled studies were reported only as conference abstracts.

Has BPC-157 been proven effective in humans?

No established evidence

No full peer-reviewed randomised controlled trial has established that BPC-157 is effective in humans. Earlier controlled studies were reported only as conference abstracts, and the available information is too limited to establish efficacy. The recent studies reporting improvement had no placebo or untreated comparison group, so they cannot show how much of the improvement came from BPC-157 rather than natural recovery, placebo effects or other care the patients received.

Has safety been established?

No

The two-person intravenous study cannot establish safety in the wider population or estimate how often adverse effects occur. Both participants had previously received intravenous BPC-157, which means the study may simply reflect people who had already tolerated it well. Larger studies in people who have not used BPC-157 before would be needed to give a reliable picture of safety. The study's authors themselves called for further research.

Are human results consistent with animal research?

Cannot be answered

The animal literature reports healing effects across many rodent injury models. Whether those effects carry over to humans cannot yet be answered, because there are no full published controlled human results to compare against.

Have the Published Human Findings Been Independently Repeated?

Independent researchers have not yet repeated these findings. All three recent full human reports have the same first author, Edwin Lee, and appeared in the same journal, Alternative Therapies in Health and Medicine.1,2,3 That does not mean the findings are wrong, but repetition by independent researchers is one of the main ways science tests whether a result holds up.

Where Does the Human Evidence Currently Sit?

Published evidence: each rung supports stronger conclusions than the one above it.

1 Laboratory studies
2 Animal models
3 Small uncontrolled reports Full published human evidence
4 Controlled human trials
5 Randomised, replicated trials
Historical controlled studies: abstract-only. Placebo-controlled trials from the 2000s were reported at meetings but never published in full.
Controlled research underway: a randomised, placebo-controlled Phase 2 hamstring trial is currently recruiting; no results are available yet. A trial in progress is research activity, not evidence of an outcome.

How We Identified BPC-157 Human Research

We searched PubMed/MEDLINE and ClinicalTrials.gov using BPC-157, BPC157, Body Protection Compound 157 and related naming variants. We also checked the reference lists of recent peer-reviewed reviews and the FDA's 2026 evidence review of BPC-157 to identify potentially relevant human studies that may not have appeared in the primary search.

We included human exposure studies, clinical reports, trials reported as conference abstracts and registered prospective interventional studies involving BPC-157. We excluded animal studies, cell studies, reviews, opinion pieces and publications without original human BPC-157 exposure data.

Our search identified the three full published human reports and, through the FDA review, the two earlier abstract-reported controlled trials described above. Recent reviews likewise characterise the full published human literature as limited to small reports involving musculoskeletal pain, interstitial cystitis and intravenous administration.9,10 Clinical-trial registries were checked separately for unpublished and ongoing research, which is how the four registered studies on this page were identified. If you know of human BPC-157 research we have missed, contact us through our contact page; our correction policy is described in our editorial standards.

Frequently Asked Questions

 

Has BPC-157 been tested in humans?

Yes. Human administration has been reported in three full published studies and in historical trial abstracts, and additional interventional studies are registered. However, the human evidence remains limited.

Are there BPC-157 clinical trials?

Yes. Four interventional studies are currently registered, including a recruiting Phase 2 trial for acute hamstring strain and a Phase 1 rotator cuff trial scheduled to start in 2027.

Has BPC-157 been proven to work in humans?

No. No full peer-reviewed randomised controlled trial has established clinical effectiveness.

Is BPC-157 safe in humans?

Human safety data are too limited to establish a reliable safety profile. Our BPC-157 side effects guide covers what has and hasn't been documented.
