I have question, I know a lot of people claim the stinging from the ghk cu is not from free copper ions, which obviously makes sense for people who know a bit about chemistry, but I just wonder what does? I know its not the bac water because I use it with other peptides and no issue. With ghk cu however it stings and skin becomes red. Why is this?
I think the main reason is because the ph. It’s a little more acidic and it depends on the concentration. That’s why if you use more bac to recon or add more bac to your dose, it doesn’t sting as bad, if at all
