Ghk-cu injection site irritation and bruising
Posted by kenji_runs in Safety & Side Effects - 8 points, 6 comments.
Honestly i reckon i might be messing up my technique or the concentration is just too high. I have been using ghk-cu for some tendon issues lately and my injection sites are a total mess. I am getting these deep purple bruises and it feels like a dull ache for a couple of days after every shot.
It is not exactly painful but it is quite annoying and i am worried i am just causing more inflammation in the area i am trying to fix. I have tried rotating sites but the bruising just follows me around.
Does anyone else find this stuff particularly harsh on the tissue? I have used other peptides and never had this happen. I am wondering if i should be diluting it more with bacteriostatic water or if i am just hitting a vein every single time. If anyone has a way to optimise the mix to stop the bruising i would be chuffed to hear it. Also does anyone have a link to actual data on tissue irritation for this specific compound? I cannot find anything concrete.

- student748: For what it is worth i had the exact same thing when i tried ghk-cu subq, deep bruises and that dull ache that lingered for days. Genuinely thought i was doing something wrong too. I ended up diluting it down quite a bit more with bac water and that seemed to take the edge off, still got some irritation but nothing like those purple bruises. Could just be my experience though, everyone seems to react differently to copper peptides. The thing i noticed is ghk-cu is just inherently irritating to
- greg_codes: Yeah diluting down more is the move, ngl. I had the same bruising mess when i ran ghk-cu subq for a knee thing. Dropped the concentration way down and the site reactions got way more manageable. Still got a bit of that ache but not the deep purple stuff. Copper peptides are just rough on tissue, seems to be the nature of it. Bpc-157 is sweet as by comparison, barely feel it.
- curious_scientist: Yeah I saw the same bruising with subq GHK‑Cu. Diluting helped a bit but I still get some soreness. Imo the copper itself seems to irritate more than BPC‑157. Are you using a 1% solution or something stronger?
- kenji_runs: Honestly i think i am on something closer to 2% right now so that might be why it is so brutal. I reckon diluting it more is my best bet if it helped you even a bit. I am quite keen to try that though. Did you find you had to use a lot more water to get the soreness down or just a tiny bit extra?
- kenji_runs: Honestly i reckon that makes sense. I am currently using a pretty concentrated mix so i might just dilute it way more with bac water and see if that helps. I am glad to hear you still get a bit of an ache though because that makes me feel less like i am doing something totally wrong. Do you think it is better to just do smaller volumes more often or just keep the concentration low?
- kenji_runs: Cheers for that mate. Honestly it is a relief to know i am not the only one getting those purple bruises. I am doing subq, so i reckon it is just the compound being harsh. I will try diluting it further with more bac water like you did and see if that helps the ache. Do you remember how much extra water you added to your mix to make it less irritating?
