Hi, When I pin GHK CU 1 MG per day I have little sting and few hours later a red circle and make bruise ... and hurt ... don't understand why, I already add more bac water, take off from the fridge 30 min to reduce it but nothing to do.... it's only on the right part of my body... on the left part nothing appear... how can we resolve that ?
It’s normal. In most cases you cannot do much about it. Over time it will probably become less severe. It took a month for me but now the sting is gone. Just light bruise for 24-48 hours
