Tissue-repair peptides

Peptides popularly discussed for healing and recovery. This group is dominated by preclinical evidence and high translation risk.

How this class works

Studied for roles in angiogenesis, tissue and gut protection, and wound biology — largely in animal models. Human clinical evidence is generally limited.

Best-supported in this class

Pentosan Polysulfate grades highest (B-tier) on current published evidence; approved members: Pentosan Polysulfate. This reflects evidence maturity — not a recommendation to use anything.

FAQ

Which tissue-repair peptides has the strongest evidence?

Pentosan Polysulfate currently grades highest in this class (B-tier) on published evidence — which reflects evidence maturity, not a recommendation.

Are any tissue-repair peptides FDA-approved?

Yes — Pentosan Polysulfate is FDA-approved for specific indications. Others in the class are investigational or research-only.

How do compounds in this class differ?

Studied for roles in angiogenesis, tissue and gut protection, and wound biology — largely in animal models. Human clinical evidence is generally limited. Within the class, members differ widely in evidence maturity, approval status, and safety — the tiers and evidence stages above show how.
