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

Tissue repair and regeneration

Reduces inflammation

Promotes new blood vessel growth

Stem cell differentiation

Cardiac tissue protection

Corneal wound healing

Hair follicle stimulation

Research Summary

Thymosin Beta-4 has extensive research spanning decades. Multiple clinical applications under investigation including corneal wound healing (RGN-259 in Phase III), cardiac repair, and dermal wound healing. Strong safety profile as a naturally occurring human protein.

BPC-157

Body Protection Compound

BPC-157 (Body Protection Compound-157) is a pentadecapeptide composed of 15 amino acids. It is a partial sequence of the body protection compound discovered in and isolated from human gastric juice. Extensive research demonstrates remarkable healing effects on tendons, muscles, the nervous system, and gastrointestinal tissue.

GHK-Cu

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.
