Does anyone have firsthand experience using GHK topically that they could pass along? I had planned to begin applying it, but after falling into a Reddit rabbit hole I came across several posts claiming it caused serious harm to people's skin. I'd really appreciate input from the hive mind of those who've actually tried it – – what helped, what backfired, what dosage, whether they combined it with their other creams, and so on.
