Last night at about 23:00 I did 1 injection of GHK Cu. 12un 2mg. To keep the sting away I put in additional BAC. It was at room temperature. Just 1 shot, SQ, into the belly. I went slowly. There was no burning, no stinging, nothing at all. Perf!! Then I slept. When I got up there was no bruising, no welts, and no itching. But a dull soreness that is quite noticeable and about the size of my hand is still there. I looked into it and there isn’t much out there besides a single article that says it’s normal inflammation caused by the copper charge. Anyway, I’m relaxing with an ice pack. I’m trying to decide whether I want to put up with dull achiness for months. Any ideas for a better spot to pin? Could a lower dose help? Should I massage the area? I’m open to advice from experts. Thank you!
