What’s the deal with GHK-Cu?
Glowing skin, luscious hair, surgery recovery, neurogenesis, anti-aging—what’s next?
It sure seems like an extremely effective compound, but nobody seems to be reaping any of its benefits. Why is that?
There are two main delivery vehicles for GHK-Cu: topical and systemic. Unfortunately, most topical serums lose a lot of their efficacy and can be classified as cope. You can try to make a betaine-and-tartaric-acid solution, but let’s be real—we aren’t doing all that chemistry shit.
Injecting subcutaneously comes with its own issues. People report intense burning and post-injection problems with this peptide. When the peptide is dissolved in bacteriostatic water, the lower ion concentration causes the copper–nitrogen bonds to break. This allows free-floating copper ions to wreak havoc on your skin. It also removes part of the benefits by un-chelating the copper from the GHK peptide.
A potential solution is to use phosphate-buffered saline (PBS). PBS can neutralize the positive charge of the copper ion, reducing the likelihood that oxidation will reduce the viability of the copper. However, PBS has a much shorter shelf life, and nobody wants to deal with bacterial growth turning into a staph infection.
Another option is to dissolve the peptide in bacteriostatic water like normal, then draw an additional 75 units of bacteriostatic water with each injection. That reduces post-injection issues, but unfortunately doesn’t do much to protect the copper.
So, TL;DR: GHK-Cu is an amazing compound, but it can cause problems if not injected correctly.
