Persistent symptoms or no measurable change after a full cycle is a sign to reassess
GHK-Cu (glycyl-L-histidyl-L-lysine-copper) is a naturally occurring tripeptide your body produces, but levels drop sharply with age, from roughly 200 ng/mL at age 20 to about 80 ng/mL by age 60
Your tissue sits at a pH around 7.4, and reconstituted GHK-Cu often falls outside that range, which activates your nociceptors (pain-sensing nerves)
If you are looking to support your skin health, joint resilience, or overall recovery, the interaction between Collagen Peptides and glutathione is a critical factor to consider
Factors affecting results speed Starting skin condition: Skin with more significant aging signs often shows more dramatic improvement than already-healthy skin
