Research peptides with claimed tissue-repair, anti-inflammatory, and angiogenic effects. Most are not FDA-approved but circulate in the supplement / research-chemical market with mechanism evidence from animal studies + small clinical trials. BPC-157 (Body Protection Compound, 15-aa) — gastric pentadecapeptide; animal-model evidence for tendon/ligament/bone healing + GI ulcer protection + angiogenesis via VEGFR2 + NO upregulation. TB-500 (synthetic thymosin β4 fragment) — actin-binding peptide; tendon repair claims; hair regrowth. GHK-Cu (copper tripeptide-1) — endogenous tri-peptide; copper-binding; skin/wound repair; collagen synthesis upregulation. Mechano growth factor (MGF) — IGF-1 Ec splice variant released by mechanically-stressed muscle; satellite-cell activator. PE22-28 — ADNP-derived fragment; neuroprotection claim.
