Peptides for Wound Healing
Overview
4 research peptides are currently studied for wound healing. This guide ranks them by evidence strength and covers their mechanisms, safety profiles, and current clinical status.
Thymosin Beta-4 — Phase III / NDA Filed
Evidence Rating: B Category: Healing & Recovery
Thymosin beta-4 (Tβ4) is a naturally occurring 43-amino acid protein found in virtually all human and animal cells. It is the most abundant member of the beta-thymosin family and plays fundamental roles in cell migration, wound healing, and tissue repair. Tβ4 is distinct from TB-500, which is a synt...
Key claims: Promotes corneal wound healing; Reduces dry eye symptoms.
Oligopeptide-1 / EGF — Phase I–II Clinical Trials
Evidence Rating: C Category: Growth Factor / Cosmetic
Epidermal Growth Factor (EGF) is a 53-amino acid protein discovered by Stanley Cohen, who shared the 1986 Nobel Prize in Physiology or Medicine for this work. EGF plays a fundamental role in cell growth, proliferation, and differentiation. In medicine, recombinant human EGF (rh-EGF) is used in wound...
Key claims: Accelerates wound healing; Reduces signs of skin aging.
GHK-Cu — No Regulatory Activity
Evidence Rating: F Category: Skin & Tissue Repair
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) found in human plasma, saliva, and urine. First discovered by Dr. Loren Pickart in 1973, plasma levels average 200 ng/mL at age 20 but decline to ~80 ng/mL by age 60. It has been extensively studied for wound heal...
Key claims: Improves skin firmness and elasticity; Promotes wound healing.
Copper Tripeptide-1 — No Regulatory Activity
Evidence Rating: F Category: Cosmetic Peptide
Copper tripeptide-1 (GHK-Cu) is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine. Note: This entry focuses on the cosmetic/dermatological use of GHK-Cu. For comprehensive coverage of GHK-Cu as a wound healing and research peptide, see the dedicated GHK-Cu entry. Copper tripeptide-1 is...
Key claims: Stimulates collagen synthesis and improves skin firmness; Promotes wound healing.

GHK-Cu: Copper Peptide in Tissue Repair and Skin Research
GHK-Cu, or glycyl-L-histidyl-L-lysine copper complex, stands out as a naturally occurring peptide central to human tissue maintenance and repair. Found in plasma, saliva, urine, and skin, its levels drop from about 200 ng/mL in young adults with age, linking to reduced regeneration. Preclinical studies highlight its roles in collagen production, wound healing, angiogenesis, anti-inflammation, and more, with the copper complex showing greater potency than unbound GHK.
TB-500: Thymosin Beta-4's Role in Healing and Repair
TB-500, known as thymosin β4, is a 43-amino-acid peptide first isolated from calf thymus in 1966 by Goldstein et al. It regulates actin in the body, supporting processes like wound healing, angiogenesis, and inflammation control. Research highlights its potential in treating conditions such as myocardial infarction, corneal injuries, and lung damage.
