Copper Peptide GHK · Glycyl-L-histidyl-L-lysine copper

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Research demonstrates it stimulates collagen, elastin, and glycosaminoglycan synthesis, promotes wound healing, reduces inflammation, and activates protective antioxidant genes. Plasma levels decline with age, making it a significant anti-aging research target.

Arg-Gly-Asp · Integrin-binding peptide

RGD (Arg-Gly-Asp) is a tripeptide sequence found in many extracellular matrix proteins (fibronectin, vitronectin, collagen) that serves as the primary recognition motif for integrin receptors. RGD-containing peptides and scaffolds are extensively used in biomaterials research to promote cell adhesion, migration, and proliferation for tissue engineering, wound healing, and regenerative medicine applications.

SP · NK1 ligand

Substance P is an 11-amino-acid neuropeptide of the tachykinin family and a primary neurotransmitter of pain signaling in the spinal cord. It binds NK1 receptors to mediate neurogenic inflammation, pain hypersensitivity, and emotional processing. NK1 antagonists have been developed for pain, depression (aprepitant), and nausea. Research also implicates substance P in wound healing, immune activation, and neuroinflammation.

Thymosin Beta-4 Fragment · Tβ4 fragment

TB-500 is a synthetic version of the active region of Thymosin Beta-4, a naturally occurring peptide found in virtually all human cells. Research shows it promotes actin polymerization and cell migration, which accelerates wound healing, muscle repair, and vascular growth. It is particularly studied for its ability to reduce inflammation and promote cardiac tissue repair.
