Beyond collagen, GHK-Cu boosts elastin production by 30% and increases decorin, a small proteoglycan that regulates collagen organization, by 302% at 1 nanomolar concentration
It can maintain balance in the body and antioxidant system by generating and removing ROS (Steinbrenner and Sies, 2009)
It inhibits tyrosinase, reducing melanin production, which addresses uneven skin tone, hyperpigmentation, and improves skin texture and radiance
While no studies have focused specifically on CJC-1295 as a muscle-building agent, the peptide clearly increases levels of serum GH and IGF-1, both of which regulate muscle mass
