TB-500 (Thymosin Beta-4) Research Wound Healing Acceleration 4261% Improvement Over Controls (PubMed, 1999) A foundational pre-clinical study published in the Journal of Investigative Dermatology investigated Thymosin Beta-4 in a rat full-thickness wound model

Key Takeaways GHK-Cu is a naturally occurring tripeptide-copper complex with documented roles in collagen synthesis and gene expression, but human RCT evidence remains absent as of 2026 Research-grade GHK-Cu must include HPLC purity 98%, mass-spectrometry identity confirmation, and bacterial endotoxin (LAL) testing in EU/mg Body Pharm supplies each vial with full per-lot traceability, including HPLC chromatogram, MS identity file and endotoxin result on request Published animal studies use 110 mg/kg subcutaneous dosing

Its effects on the skin are wide-ranging and well documented: Stimulates Collagen and Elastin: Collagen is what gives skin its firmness, while elastin contributes to elasticity

In chronic wounds, a 2021 RCT (n=72 diabetic ulcers) reported 85% closure rate with GHK-Cu dressings at 12 weeks versus 55% control (OR 4.2
