Body protection compound-157 (BPC-157) is a substance found naturally within the body that supports healthy organs and tissues. In particular, it is a gastric peptide that helps to maintain mucosa integrity and homeostasis. Early research shows that it may help with musculoskeletal injuries like fractures, tendon ruptures, muscle injuries, and ligament tears (1).
Studies show that BPC-157 works multifactorially, by indirectly or directly up regulating cell growth, proliferation, survival, anti-inflammation pathways, and angiogenesis. In particular, it reduces inflammatory cytokines while enhancing growth hormone receptor expression, leading to musculoskeletal improvements (1).
A systematic review of the literature for research involving BPC-157 yielded 36 studies of interest, with 35 being preclinical studies and one being a clinical study in humans.
The research showed that in preclinical models, treatment with the substance led to better functional, structural, and biomechanic outcomes in the ligament, tendon, muscle, and bony injuries. These preclinical safety studies indicated that there were no adverse events in multiple different organs (1).
Within the one clinical study, patients with unspecified chronic knee pain were treated with intra-articular injection of BPC-157. Out of the 12 patients, seven reported symptom relief for greater than six months. However, no clinical safety data is available (2).
The body of evidence supporting BPC-157’s use in humans remains minimal. While several patients in the single clinical study available experienced benefit, this was a retrospective study with a small sample size of only 12 patients.
It is important to note that BPC-157 is not approved by the US Food and Drug Administration (FDA). In 2023, the FDA termed it a Category 2 bulk drug substance. This means that BPC-157 is not allowed to be compounded by pharmaceutical companies and there is not substantial evidence regarding it’s risk profile in humans. However individuals can still get BPC-157 via dietary supplements. Several medical clinics with licensed physicians in the US provide BPC-157 as an available treatment.
As dietary supplements, BPC-157 is not regulated by the FDA. Thus, the quality and safety of the product is unknown.
Additionally, BPC-157 has been banned for use in professional sports. However, it is to illegal to possess as it is not a Drug Enforcement Agency (DEA) scheduled substance (1).
Adverse of effects BPC-157 have yet to be characterized in humans. However, they are possible, specifically those related to the lack of regulation of the product. Physicians and patients should be cautious of contamination concerns and the lack of known clinical safety (1).
Preliminary research shows that BPC-157 can support structural, functional, and biomechanics recovery in the musculoskeletal system. However, while no adverse events were noted in preclinical animal models, the risk in humans is not known. While BPC-157 certainly shows promise, further clinical studies are needed to validate this initial data.
The information provided in this article is for educational purposes only and is not intended as medical advice. Many peptides are not FDA-approved for human use outside of limited clinical contexts. These compounds are often obtained through unregulated sources that lack quality control. Studies suggest 30–65% of products may be contaminated or mislabeled, with risks including endotoxins, heavy metals, and incorrect sequences. At Weight Loss & Vitality, we focus on evidence-based, medically supervised therapies.
As of April 21, 2026, regulatory status for many peptides remains under review and may change as additional data and guidance become available.
While many peptides are still being studied, their effects on the body can be significant. Our medically supervised peptide treatments are designed to ensure safe, personalized care aligned with each patient’s health goals.
Update — July 13, 2026
Since this article was originally published, Weight Loss & Vitality has begun offering this peptide in select clinical circumstances when it can be legally prescribed and dispensed through an appropriately licensed pharmacy. Treatment is considered only for patients who meet our clinical eligibility criteria following an individualized medical evaluation, review of potential risks and benefits, and informed consent. The availability of a peptide through a licensed pharmacy does not necessarily mean that the peptide or its intended use is FDA-approved, nor does it establish safety or effectiveness for every patient or medical condition. When prescribed, peptide therapy is provided under medical supervision with appropriate patient counseling, follow-up, and monitoring based on the individual treatment plan.
