The Strange Science of the Copper Peptide
1/4) GHK-Cu is among the weirdest peptides... once you understand how it works.
First, consider this: Copper is an element that’s essential for human biology. It sits at the core of enzymes involved in collagen production + antioxidant defenses+ mitochondrial metabolism.
And naturally, GHK-Cu levels decline with age, falling by over 50% between ages 20 and 60.
But here’s the catch: You can’t just give the body free copper. Free copper ions can accelerate oxidative stress and cellular aging.
So, on one hand, you need copper for proper metabolic health and longevity… but on the other hand, excess free copper can actually promote aging.
GHK-Cu appears to solve this problem.
