BPC-157: research, legal status and who sells it

What it is

BPC-157 (“body protection compound 157”) is a synthetic 15-amino-acid peptide whose sequence was originally isolated from gastric juice [10]. It has no United States Adopted Name and is not a component of any FDA-approved drug [2].

Research status

Most of the evidence comes from animal studies [11]. A 2025 systematic review of the orthopedic literature found 36 eligible studies, 35 of them preclinical, and no clinical safety data [11]. Animal studies report better healing of tendon, ligament, muscle and bone injuries [11], but a 2019 review noted that most studies used small rodent models, that only a handful of research groups have studied the peptide in depth and that its efficacy has not been confirmed in humans [12]. Human data are very limited: FDA’s 2026 review found five small, short clinical studies, in healthy volunteers and in people with ulcerative colitis, knee pain or interstitial cystitis, with little safety reporting [2]. A 2026 review in Sports Medicine concluded that rigorous human safety data are scarce for unapproved peptides such as BPC-157 [13].

Regulatory status

BPC-157 is not FDA-approved [1]. In its review for the July 2026 advisory committee meeting, FDA staff concluded that the evaluation criteria weigh against adding BPC-157 to the list of bulk substances that pharmacies may use in compounding [2]. The agency’s advisory committee voted 8–6 in favor, but the vote is not binding and FDA has not added it [14][3]. In Australia, BPC-157 is a Schedule 4 prescription-only poison, and possession without authority is prohibited [8]. WADA names BPC-157 as a prohibited non-approved substance [9].

Quality and testing considerations

FDA says it has encountered multiple salts and derivatives, including different active moieties, sold under the BPC-157 name, and that inconsistent naming is a safety risk [2]. Its earlier safety flags concerned possible immune reactions (immunogenicity) and peptide-related impurities [15]. Reviewers also warn of harm from unregulated manufacturing and contamination [11]. A certificate of analysis should state which form was tested, free base or acetate, because FDA treats them as distinct substances [2], and identity should be confirmed by mass spectrometry.

Where it’s sold

BPC-157 is sold online as a “research use only” product, and FDA notes it is also sold as an ingredient in oral dietary supplements [2].
