A bunch of Reddit users are saying they used GHK-Cu injections and their keloid scars got noticeably better. The posts are basically people sharing personal experiences and asking others if they tried the same. There’s no formal study mentioned in the snippet — just social media reports and people wanting to swap notes. GHK-Cu is a small molecule made of three amino acids (a peptide) bound to copper. People often call it a “peptide” because it’s a short chain of the building blocks of proteins. It’s been studied for things like wound healing and skin repair because it can influence cells involved in making and remodeling connective tissue. That said, hearing about it on Reddit doesn’t mean it’s a proven treatment for keloids. The claim here is anecdotal: several users say their keloids remodeled after getting GHK-Cu injections. The snippet doesn’t give details like how many people total, exact changes in scar size or appearance, how long it took, dose, frequency, or whether a doctor administered the injections. Anecdotes can be a useful starting point, but they aren’t the same as controlled clinical trials. Without controlled data, we can’t tell if the improvements were due to the peptide, normal scar evolution, placebo effect, other treatments used at the same time, or simply selective reporting (people post success stories more than failures). This matters because keloids are stubborn, raised scars that can be painful or embarrassing, and current treatments (steroid injections, surgery, laser, silicone sheets, radiation) don’t work consistently. If GHK-Cu really helps, it could become another tool for people suffering from keloids. For patients and clinicians, anecdotal buzz can prompt formal research. For someone with keloids who’s exhausted other options, these reports might spark hope — but they should be a prompt to talk with a dermatologist, not a how-to. There are important caveats. The Reddit posts are not controlled evidence. We don’t know safety details from that snippet: injection quality, sterility, dosing, side effects, or who administered them. GHK-Cu isn’t an FDA-approved treatment for keloids specifically, and self-injecting compounds bought online carries infection and dosing risks. People with certain medical conditions, pregnant or breastfeeding people, and those on blood thinners should be cautious. Always check with a qualified clinician before trying off-label or experimental treatments, and look for published clinical trials or dermatologist guidance. Bottom line: several people online report nicer-looking keloids after GHK-Cu injections, but those are just anecdotes — promising enough to ask questions, not enough to change medical practice.
