Peptide index
331 compounds across 19classes. Each one carries an evidence tier, because “there are studies” means something very different for semaglutide than it does for most of this list.
16 compounds
Actovegin
Human RCTA calf-blood extract injected into injured muscle in European sports medicine, credited with faster return to play but built on a poorly characterised mixture rather than a defined drug.
Healing, Repair & Regenerative
ARA-290
Human RCTAn 11-amino-acid fragment of erythropoietin that keeps EPO's tissue-repair signalling for damaged nerves while dropping the blood-thickening effect entirely.
Healing, Repair & Regenerative
BPC-157
Animal data onlyThe best-known repair peptide, used for tendon, ligament, gut and nerve injuries on the strength of a very large rodent literature and essentially no completed human efficacy trials.
Healing, Repair & Regenerative
BPC-157 Arginate
Animal data onlyThe arginine-salt form of BPC-157, sold because it holds up far better in solution and at room temperature than the usual acetate salt.
Healing, Repair & Regenerative
Collagen Peptides
Human RCTEnzymatically broken-down collagen taken orally, where the surviving di- and tripeptides act as signalling fragments telling fibroblasts to build more matrix.
Healing, Repair & Regenerative
Elafin
Human RCTA human elastase inhibitor given intravenously in clinical trials to protect gut, lung and vascular tissue from neutrophil-driven damage after major surgery or severe inflammation.
Healing, Repair & Regenerative
GHK-Cu
Human trialsA copper-binding tripeptide that switches on collagen, elastin and antioxidant gene programmes, used topically for skin remodelling and subcutaneously for wound and tissue repair.
Healing, Repair & Regenerative
KPV
Animal data onlyThe three-amino-acid tail of alpha-MSH, used for gut, skin and mast-cell driven inflammation because it blocks NF-kB without the tanning or libido effects of the parent hormone.
Healing, Repair & Regenerative
LL-37
Human trialsThe only human cathelicidin, a cationic antimicrobial peptide that kills bacteria and biofilms directly while also driving angiogenesis and wound closure.
Healing, Repair & Regenerative
Osteogenic Growth Peptide
Animal data onlyA histone-derived bone peptide that stimulates osteoblast proliferation and marrow activity, used experimentally for fracture healing and bone density.
Healing, Repair & Regenerative
Pentadeca Arginate
Animal data onlyA marketing name for arginate-salt BPC-157 that spread rapidly after US compounding restrictions, chemically near-identical to what it replaced.
Healing, Repair & Regenerative
Pentosan Polysulfate Sodium
Approved drugA heparin-like sulfated sugar polymer, approved orally for interstitial cystitis and used by injection in veterinary and Australian practice as a disease-modifying osteoarthritis drug.
Healing, Repair & Regenerative
Substance P
Animal data onlyA sensory neuropeptide central to wound healing and corneal repair that is far more often a drug target to be blocked than a compound anyone should be injecting.
Healing, Repair & Regenerative
TB-500
Animal data onlyThe standard partner to BPC-157 for soft-tissue injury, working through actin regulation to speed cell migration, new blood vessel growth and lower fibrosis.
Healing, Repair & Regenerative
Thymosin Beta-4
Human RCTThe full-length parent peptide behind TB-500, with real randomised human trial data in dry eye and corneal wound healing rather than just rodent injury models.
Healing, Repair & Regenerative
VIP
Human trialsA 28-amino-acid neuropeptide used as a nasal spray in chronic inflammatory response syndrome protocols and intravenously in critical-care trials, valued for broad neuroimmune and pulmonary anti-inflammatory effects.
