In rats, mice, and pigs, treatment with GHK-Cu assisted in increasing the rate of systemic wound healing
Mechanism of Action Comparison IGF-1 LR3 Reduced IGFBP-1, -2, -3 binding affinity Extended circulating half-life (~20-30 hours) Sustained IGF-1 receptor activation Full receptor binding affinity maintained IGF-1 DES Reduced IGFBP binding via truncation Short half-life (~20-30 minutes) Rapid, acute receptor activation Enhanced receptor binding potency reported Research Applications Comparison The choice between IGF-1 LR3 and IGF-1 DES depends on the specific temporal requirements of your research
