A common claim online is that copper destroys peptides like BPC-157 and TB-500.
But the copper used in GHK-Cu isn’t free copper ions floating around.
It’s copper bound to the GHK peptide.
When metals bind to molecules, their chemical behavior can change significantly.
The phrase copper kills peptides is an oversimplification of a more complex chemical interaction
Copper can catalyze oxidation reactions but not all peptides are equally sensitive to it
Stability depends heavily on the peptide’s structure and surrounding environment
Some lab protocols intentionally include metal ions for structural stabilization
Real-world peptide stability is influenced by many variables not one element
Analytical testing like HPLC helps confirm whether degradation actually occurs
Pharmaceutical formulations account for metal interactions during development
Research labs routinely test peptide stability under multiple conditions
Some peptides break down mainly through hydrolysis rather than oxidation
