What is Thymosin Beta-4?
Thymosin Beta-4 (TB4) is a naturally occurring 43-amino acid peptide present in nearly all human cells. It is the primary G-actin sequestering molecule in cells and plays fundamental roles in tissue repair, cell migration, blood vessel formation, and anti-inflammation. TB-500 is its synthetic fragment.
Key Benefits & Mechanisms

Copper Peptide (Glycyl-L-Histidyl-L-Lysine-Copper)
GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It declines with age and plays critical roles in wound healing, tissue remodeling, collagen synthesis, and anti-inflammatory signaling. Extensively studied for skin rejuvenation and anti-aging applications.
