Quick verdict
For BPC-157, the most discussed peptide, a 2025 systematic review found 36 studies: 35 preclinical and one clinical. The review notes it lacks FDA approval and is banned in professional sports. Human evidence for longevity is absent. This page gives no protocols and no sourcing guidance.

The short answer: the human evidence for longevity peptides is close to non-existent. For BPC-157, the most discussed one, a 2025 systematic review found 36 studies, of which 35 were preclinical (cells and animals) and only one clinical. The review notes it lacks FDA approval and is banned in professional sports. Nothing on this page is a protocol or a sourcing tip. Talk to your doctor.
What the evidence shows
Grade: Not shown in humans.
| Item | Evidence | Limit |
|---|---|---|
| BPC-157 | Systematic review: 544 articles identified, 36 included, 35 preclinical and 1 clinical; in animal models it improved muscle, tendon, ligament and bone healing outcomes; the one clinical study was retrospective (musculoskeletal pain after intraarticular injection) | Animal results do not establish human benefit or safety |
| Regulatory status | The same review states BPC-157 lacks FDA approval; FDA’s 503A bulks page (updated 14 May 2026) describes the framework but did not name specific peptides in the text we could read | Rules change; check FDA directly |

Common questions
Is BPC-157 proven in humans?
No. A 2025 systematic review of the literature to June 2024 found 544 articles and included 36 studies, of which 35 were preclinical and 1 was clinical (a retrospective study of musculoskeletal pain after injection). It also states BPC-157 lacks FDA approval and is banned in professional sports.
Are longevity peptides legal to buy?
It depends on the peptide and the country, and the rules change. The 2025 review says BPC-157 lacks FDA approval. FDA maintains a page on bulk drug substances that pharmacies may compound; we could not confirm from it the status of specific peptides. Check the FDA directly and talk to a physician. This page does not explain how to obtain any peptide.
