AHK-Cu

What is it?
AHK-Cu is a copper-containing tripeptide closely related to GHK-Cu, but with a slight structural difference that makes it more specifically active in hair follicle biology. Research focuses on its ability to grow hair follicles and protect the cells that control hair growth.

Key Benefits (from research)

– Lengthens hair follicles – An ex vivo study on human hair follicles showed AHK-Cu stimulated follicle elongation in a dose-dependent manner.

– Promotes growth of dermal papilla cells – These are the critical cells that govern hair cycling; AHK-Cu increased their proliferation in laboratory studies.

– Protects follicle cells from dying — The same study found reduced levels of cell-death proteins (caspase-3 and PARP) and a higher ratio of survival proteins, suggesting anti- apoptotic activity.

– Raises VEGF in skin fibroblasts – Research documents increased production of the blood vessel growth factor VEGF, which supports the vascular environment around follicles.

– Reduces pro-scarring signals – Unlike many growth factors, AHK-Cu also suppresses TGF- ẞ1, which drives fibrosis and scarring in the skin.

– Supports collagen and ECM integrity – As a copper-bound peptide, AHK-Cu participates in the copper-dependent cross-linking of collagen fibres, relevant to skin structure research.

More Information
TB-500 is a synthetic analogue of the active region of Thymosin Beta-4, a naturally occurring protein found throughout body tissue. It has been widely studied in preclinical models for its role in cell migration, wound healing, angiogenesis, and skeletal muscle repair. Believed to work primarily by upregulating actin binding protein. For laboratory research use only.
