Hi everyone! I'm new to this and trying to find some reputable sources for what's considered cosmetic grade GHK-Cu. I've heard people get it from overseas suppliers, but I'm not really comfortable with that yet. I saw one brand mentioned positively here (aside from the stinging, lol) and wondered if their raw powder is the same thing as cosmetic grade, or if it’s the injectable kind that needs reconstitution? I just want the stuff to mix into my lotions! Any guidance or recommendations would be super appreciated!
