BPC-157: what the research shows

What BPC-157 is

BPC-157 (body protection compound 157) is a pentadecapeptide, a chain of 15 amino acids, described in the literature as a gastric peptide that promotes mucosal integrity. [1] [2]

It is not an approved medicine. A 2025 systematic review notes that BPC-157 lacks US Food and Drug Administration approval and is banned in professional sport, yet is increasingly used by clinicians and athletes. [2]

What the research covers

Most of the evidence comes from animal studies. A 2019 review of musculoskeletal soft-tissue healing found consistently positive results for tendon, ligament and skeletal-muscle injury, but noted that the majority of studies were done in small rodent models, that efficacy in humans had yet to be confirmed, and that only a handful of research groups had studied the peptide in depth over two decades. [1]

A 2025 systematic review screened 544 articles published between 1993 and 2024 and included 36 studies: 35 preclinical and 1 clinical. In the preclinical models, BPC-157 improved functional, structural and biomechanical outcomes in muscle, tendon, ligament and bone injuries; the studies suggest it enhances growth-hormone-receptor expression and pathways of cell growth and angiogenesis while reducing inflammatory cytokines. [2]

The same review reports that, in preclinical work, BPC-157 is metabolised in the liver, has a half-life of less than 30 minutes and is cleared by the kidneys. [2]

What is not known

Human data are very limited. The 2025 systematic review found a single small retrospective clinical study and no clinical safety data, and it warns that adverse effects are possible because of unregulated manufacturing, contamination or unknown clinical safety. [2]

A 2025 pilot study in two adults reported no measurable changes in the heart, liver, kidney, thyroid and blood-glucose markers it tested. With two participants, it cannot show whether BPC-157 is safe; its authors call for further studies. [3]

Status in sport

The World Anti-Doping Agency's 2026 Prohibited List names BPC-157 in class S0, non-approved substances: pharmacological substances with no current approval by any governmental health authority for human therapeutic use, prohibited at all times, in and out of competition. [4]

Storage and stability in the lab

Peptides can degrade through chemical routes such as oxidation, deamidation and hydrolysis and through physical routes such as aggregation, and they are generally more stable in the dry state than in solution. [5]

Lyophilised vials are therefore normally kept cold, dry and away from light until they are reconstituted. The storage statement on the product page and on the batch certificate takes precedence.

How to check a batch

A useful certificate of analysis names the testing laboratory, the batch number printed on the vial, the test date and the methods used. Identity is usually confirmed by mass spectrometry, where the measured mass should match the expected molecular mass, and purity is measured by HPLC. The 2025 review's warning about unregulated manufacturing and contamination is the reason to look for a batch-specific report. [2]

Where the manufacturer supplies a batch report, we link it on the product page; products without one do not claim one.
