Beta-Alanyl-L-Histidine · L-Carnosine

Carnosine is a naturally occurring dipeptide (β-alanyl-L-histidine) found at high concentrations in skeletal muscle and the brain. It acts as a pH buffer in muscle (reducing acidosis during high-intensity exercise), a powerful antioxidant, an antiglycation agent (preventing protein-sugar crosslinking), and a chelator of zinc and copper. Research explores its role in aging, cognitive decline, autism, and exercise performance.

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.
