The compound's role in advancing our understanding of aging mechanisms, developing intervention strategies, and exploring the research potential of senescent cell elimination positions it at the forefront of aging research priorities
Research on GHK-Cu's regenerative mechanisms published in PMC confirms the age-related serum decline from roughly 200 ng/mL at age 20 to 80 ng/mL by age 60, underpinning the rationale for supplementation in aging tissue
