Best Peptides for Tissue Repair & Recovery: Ranked by Evidence (2026)

Recovery peptides such as BPC-157 and TB-500 are popular but unapproved; their evidence comes mostly from animal studies, and both are prohibited in sport. The ordering below is by strength of evidence and regulatory status, not by brand.

Frequently asked questions

Which tissue repair & recovery peptides are FDA-approved?

None of the compounds in this category has an FDA-approved product.

How is this list ordered?

By regulatory status first (FDA-approved, previously approved, in clinical trials or approved abroad, preclinical), then by the number of PubMed-indexed clinical-trial papers. It ranks evidence, not sellers, and no company can pay to change the order.

Can I buy these online?

FDA-approved drugs require a prescription. Products sold as "research peptides" are labeled not for human use and are not FDA-approved; see each compound page for its status and our vendor directory for documented facts about sellers.
