6 published reports

118 people enrolled, about 83 given BPC-157

2 with a placebo group, both from the early 2000s

4 trial registrations, 0 with results

Tested in people Counted from the table below. The colitis trial did not say how many of its 53 people got BPC-157, so half are counted. Not included: 40 people in a finished 2025 gummy study that has posted no results.

What it is
A lab-made chain of 15 amino acids, first described in 1993 as a fragment of a stomach protein
Evidence
Mostly rats. In people: two placebo-controlled enema studies and four uncontrolled reports
Best human result
No placebo-controlled benefit. The colitis trial gap was not statistically clear
FDA status
Regulatory fact Not part of an approved drug in any country. Not yet allowed for US pharmacy compounding: an FDA committee recommended it in July 2026 and no rule has followed as of October 2026
Sport (WADA)
Regulatory fact Banned at all times under S0, where the 2026 list names it as an example

Every published study that gave BPC-157 to people

Six reports, oldest first. Two were placebo-controlled enema studies from Pliva, the company that developed BPC-157. Four had no control group, so they cannot separate the drug from natural recovery or expectation.

Tested in people: each row checked against its source on October 21, 2026
YearStudy and designPeopleWhat happened
2002 to 2003 Safety and blood levels of an enema form in healthy volunteers Randomized, placebo-controlled phase 1 Pliva, Croatia (M. Veljaca and colleagues). Two meeting abstracts (IUPHAR-GI symposium 2002; Gut 2003), never a full paper. Summarized in FDA briefing document, Appendix 1 32 Healthy men; 24 got BPC-157. Most blood samples held too little BPC-157 to measure. The study tested safety, not benefit. Safety: No significant adverse events put down to BPC-157. Headache and flatulence were the most common events, with no obvious difference from placebo.
2005 Two-week enema trial in mild to moderate ulcerative colitis Randomized, double-blind, placebo-controlled Pliva-linked investigators (M. Ruenzi, M. Veljaca and others). Meeting abstract (Gastroenterology 2005), never a full paper. Summarized in FDA briefing document 53 Adults with mild to moderate ulcerative colitis. Randomized 1:1; the abstract does not give the split. 46 completed. Disease activity fell 3.2 points on BPC-157 and 1.6 on placebo. The gap between groups was not statistically clear (95% CI -4.84 to 1.62). Safety: Three people on BPC-157 and two on placebo left early because of adverse events, mainly worsening colitis.
2021 Knee injections reviewed from charts, with a phone survey Retrospective chart review, no control group Institute for Hormonal Balance, Orlando (E. Lee, B. Padgett). Alternative Therapies in Health and Medicine. Lee and Padgett 2021, PubMed 16 Adults with knee pain at one clinic. 17 charts found, 16 reached. 12 had BPC-157 alone, 4 had BPC-157 plus thymosin beta-4. 11 of the 12 who had BPC-157 alone said their knee pain improved a lot; 3 of the 4 on the combination did. No standard pain or function scale was used. Safety: The authors noted no adverse events.
2024 Bladder-wall injections for interstitial cystitis Single group, no control Private clinic in Florida (E. Lee, C. Walker, B. Ayadi). Alternative Therapies in Health and Medicine. Lee, Walker and Ayadi 2024, PubMed 12 Women aged 39 to 76 whose interstitial cystitis had not responded to pentosan polysulfate. 10 of 12 reported their symptoms fully gone after one procedure; the other 2 rated their improvement at 80%. Safety: No one dropped out and no adverse events were reported.
2025 Two days of IV infusions in healthy adults Single group, no control Private clinic in Florida (E. Lee, K. Burgess). Alternative Therapies in Health and Medicine. Lee and Burgess 2025, PubMed 2 A 58-year-old man and a 68-year-old woman who had used IV BPC-157 before. No measurable change in heart, liver, kidney, thyroid or blood sugar markers over three days. Safety: No side effects reported.
2026 Three dental patients with a numb lip and chin after surgery Case report, no control Stony Brook University dental school and private practices (S. Froum and colleagues). Frontiers in Oral Health, September 30, 2026 (case report). Froum et al. 2026, PMC 3 Three patients with lower-jaw nerve injury after implant or extraction surgery. BPC-157 was one of five drugs in the same injection, with TB-500, ARA-290, dexamethasone and bupivacaine. Feeling came back almost fully in all three after a four-week course of injections near the nerve. The authors write that natural recovery cannot be ruled out and the cases do not show cause. Safety: No adverse events reported.

FDA's reviewers read the Pliva conference abstracts, which are not online, and summarized them in their 2026 briefing document; those two rows come from that summary. Link to a row by its anchor, such as #ruenzi-2005. How to judge a design like these: how to read peptide research.

Tested in people. Numbers are people enrolled or randomized as each source reports them; for the knee survey, the 16 people the authors reached.

What BPC-157 clinical trials are registered?

Four on ClinicalTrials.gov, none with posted results. Two are placebo- or sham-controlled trials that have not finished, with 150 people planned between them. The 2015 tablet trial has posted no results and FDA found no published paper, and the 2025 gummy study, which enrolled 40 people, has posted no results.

NCT07803250 on ClinicalTrials.gov

Regulatory fact Registry records as shown on ClinicalTrials.gov on October 21, 2026. The rotator cuff record lists its control arm as "Sham (No Treatment)" while its summary describes a saline placebo and 20 patients against 30 planned in the enrollment field; we report the arm and the enrollment field as listed. The 2015 oral trial is often described online as cancelled, but the registry shows its status as unknown.

Who ran the BPC-157 human studies?

Mostly two sources. Three of the six reports come from one Florida physician, E. Lee, and two from Pliva, the Croatian company that developed BPC-157 as PL 14736.

The three Florida reports, on knee pain in 2021, interstitial cystitis in 2024 and IV infusions in 2025, all name Lee as first author and all appeared in Alternative Therapies in Health and Medicine. None had a control group. Together they hold 30 people, the same 30 a 2026 systematic review counted and rated as very low certainty evidence.

Both Pliva studies list the company researcher M. Veljaca as an author, and neither went beyond a conference abstract. FDA found no approved BPC-157 product in any country. The animal research, starting with the University of Zagreb group that described BPC-157 in 1993, is on the BPC-157 profile.

Why do sources give different numbers of BPC-157 human studies?

They searched at different times and counted different things. Some leave out conference abstracts, some stick to sports injuries, and the newest report came out after every review.

Does BPC-157 cause cancer?

Tested in animals or cells Nobody knows. No study has shown it does, and no study has looked.

In lab tests reported in 2020, BPC-157 did not cause gene mutations in bacteria or chromosome damage in hamster cells or mouse bone marrow (Xu 2020). That is a screen for one way drugs can cause cancer, not a cancer study. FDA's 2026 reviewers found no long-term cancer studies of BPC-157 in animals.

The worry comes from blood vessel growth: in rats with blocked leg arteries BPC-157 increased blood vessel growth, and in cell experiments it switched on VEGFR2, a signal tumors also use to build their blood supply (Hsieh 2017).

Tested in people None of the six reports looked for cancer, and none followed anyone longer than about a year. The side effects that were reported are on the BPC-157 profile.

What has nobody tested in people yet?

Any injury, the injected and oral forms people use, and use for longer than a month. FDA concluded in 2026 that there is not enough clinical safety information to describe its safety.

  • A placebo-controlled trial for any injury. No tendon, ligament, muscle or joint injury has been tested against placebo in people. The hamstring trial in China is the first, and it is not due to finish before 2028.
  • How much reaches the blood after an injection or a pill. FDA found no human blood-level data after oral, under-the-skin, nasal or skin use. The only human blood measurements come from the Pliva enema studies.
  • Use longer than four weeks. The longest exposure in any report is the four-week course in the dental cases. Nobody has followed regular users for months or years.
  • Antibodies and immune reactions. No study has checked whether people form antibodies to injected BPC-157, a risk FDA flagged in 2026 because peptides can clump together and carry impurities from manufacturing.
  • Cancer risk over time. No report followed people long enough to see whether a cancer starts or grows. The longest follow-up was the knee survey, 6 months to a year after the injection.
  • The BPC-157 and TB-500 combination. Two uncontrolled reports paired them: 4 knee patients got BPC-157 with thymosin beta-4 (the paper does not say which form), and the 3 dental cases got it with TB-500 among other drugs. No controlled human study has tested the pair.

Legal status is covered step by step on is BPC-157 legal: an FDA advisory committee voted 8 to 6 on July 23, 2026 to recommend allowing pharmacies to compound it (reported by AJMC), and as of October 21, 2026 no proposed rule has appeared in the Federal Register. How it compares with TB-500, which has never been tested on its own in people: BPC-157 vs TB-500.

How this count was made

  1. 1
    Searched PubMed

    Every name BPC-157 has gone by, including Pliva's code PL 14736 and the trade name Bepecin, in titles and abstracts. We screened the titles of all 230 records and read the abstract of every one that could involve people.

  2. 2
    Read FDA's list

    FDA's 2026 briefing document lists five human studies, including the two Pliva studies, known only from conference abstracts that are not on PubMed. We used FDA's summary for those two.

  3. 3
    Searched ClinicalTrials.gov

    By intervention and keyword for BPC-157, BPC 157, PL 14736, PCO-02 and pentadecapeptide, then read each record. Records that only matched loosely were dropped.

  4. 4
    Counted what each source says

    People enrolled as the paper reports them. Lab studies on human tissue, such as artery rings from bypass surgery, are not counted, because no person took the peptide.

  1. Oct 21, 2026

    Ledger published with 6 reports and 4 registrations. Adds the September 30, 2026 dental case report, which no earlier count includes. Rechecked monthly.

Frequently asked questions
Has BPC-157 been tested in humans?
Only in small studies. As of October 21, 2026, six published reports have given BPC-157 to people, 118 people in all and about 83 of them on BPC-157. Two were placebo-controlled enema studies from the drug company Pliva in the early 2000s, published only as conference abstracts. The other four are uncontrolled reports from Florida clinics and dental practices with 2 to 16 people each.
Are there any BPC-157 clinical trials?
Four are registered on ClinicalTrials.gov, and none has posted results. A 2015 oral tablet trial in Mexico was never updated after December 2015. A gummy study in 40 people finished in 2025. A 120-person placebo-controlled trial in hamstring strains has been recruiting in China since February 2026, and a 30-person trial after rotator cuff surgery in Arkansas is set to start in January 2027.
Has a placebo-controlled trial shown that BPC-157 works?
No. The only placebo-controlled test of benefit, a two-week enema trial in 53 adults with ulcerative colitis, found disease activity fell in both groups and the gap between BPC-157 and placebo was not statistically clear. It was published only as a 2005 conference abstract, and FDA called its data inadequate to support efficacy.
Does BPC-157 cause cancer?
No study has shown that it does, and no study has looked. Tested in animals or cells: lab tests found no gene mutations or chromosome damage, but FDA found no cancer studies in animals, and BPC-157 grows new blood vessels in rats, which tumors also use. Tested in people: no report followed anyone longer than about a year, so the risk is unknown.
What side effects were seen in the human studies?
None serious. Headache and flatulence were the most common events in the healthy-volunteer enema study, with no obvious difference from placebo. In the colitis trial, three people on BPC-157 and two on placebo left early, mainly because their colitis got worse. The Florida and dental reports said no adverse events, but they had no control group and short follow-up. FDA concluded in 2026 that there is not enough clinical safety information to describe its safety.
Why do websites give different numbers of BPC-157 human studies?
They searched at different times and counted different things. A 2025 sports-medicine review found 1 clinical study, FDA found 5 in December 2025, and a 2026 review that kept only the three Florida reports counted 30 people. This page adds the two Pliva studies, known only from conference abstracts, and a dental case report published September 30, 2026.
Who ran the BPC-157 human studies?
Three of the six reports come from one Florida physician, E. Lee, published in the same journal. Two come from Pliva, the Croatian drug company that developed BPC-157 as PL 14736, and both list the same Pliva researcher as an author. The sixth is a 2026 dental case report from Stony Brook University and private practices.
