Research compound aggregated from creator and literature mentions. No direct disease-treatment claims are made on this page.
Experts on background and overview · 11 cited mentions
"The amount of copper from what I remember, a 2 mg dose of GHK is only... 17% based on molecular weight. About 150 micrograms from what I remember for a 2 mg. Like it's nothing if you look at like your RDA of copper."
"Of course you take it with all the collagen synthesis agents like growth hormone and oxandrolone... You inject the GSK copper locally into the tricep or another body part that you're trying to spike."
"Some people run GHK-Cu 5 to 10 mg just the entire way through their diet and the skin retracts, but I've never seen any before and after pictures of that protocol, only heard that anecdotally"

"GK copper 10 milligrams per day. That's um separately now, but I'll get some close stacks and then just do one single shot."
"GHK copper is FDA approved? It's probably gray area - I don't think it's illegal but I don't think it's FDA approved. It might be on the compounding pharmacy list."
"If we're looking at specifically improving copper locally in the hair follicle or within the scalp, topical would probably be better than systemic."
"I got some topical BPC-157 and GHK copper that I'm using right now to kind of help with the incision, right? So, that's healing quite nicely."
"there are some people that I've seen get some nutty reactions from GHK-Cu... a lot of people get the itch at the injection site."
"You create a little bit of adhesions, you know, the GHK-Cu injections for example."
"I don't I don't think that GHK-Cu shown um tumor and cancer proliferating effects"
"GHK copper and then um this renewal supplement with urolithin."
