Comparison

GHK-Cu vs Thymosin Beta-4

Function

While GHK-Cu acts as a tissue-remodeling and wound-healing signal, enhancing skin regeneration, angiogenesis, and repair while reducing inflammation and oxidative damage in experimental models31383, Thymosin Beta-4 promotes wound healing, angiogenesis, and tissue regeneration in preclinical models via effects on cytoskeleton dynamics, cell migration, and anti-apoptotic pathways25579.

Mechanism

While GHK-Cu works as an endogenous tripeptide, Gly-His-Lys, that chelates Cu²⁺ and modulates gene expression, stimulating collagen, elastin, proteoglycan, and glycosaminoglycan synthesis while exerting antioxidant and anti-inflammatory effects31383, Thymosin Beta-4 is an endogenous 43-amino-acid actin-sequestering peptide that maintains a pool of G-actin monomers and regulates actin polymerization, thereby influencing cell migration, proliferation, and differentiation25579.

Length and Sequence

GHK-Cu is 3 amino acids long, whereas Thymosin Beta-4 is longer as it has a length of 43 amino acids. GHK-Cu is made up of a sequence of Glycine, Histidine, Lysine. Thymosin Beta-4 is made up of a sequence of Serine, Aspartic acid, Lysine, Proline, Aspartic acid, Methionine, Alanine, Glutamic acid, Isoleucine, Glutamic acid, Lysine, Phenylalanine, Aspartic acid, Lysine, Serine, Lysine, Lysine, Proline, Aspartic acid, Methionine, Alanine, Glutamic acid, Glutamic acid, Lysine, Phenylalanine, Aspartic acid, Lysine, Lysine, Glutamic acid, Lysine, Lysine, Glutamic acid, Glutamic acid, Alanine, Glutamic acid, Asparagine, Glutamic acid, Glutamic acid, Lysine, Glutamic acid, Serine.
