Agreed with the something being seriously wrong. Get bloodwork asap. Could have dirty bac water as well, someone pointed out a few months back that a few sources are selling bunk bac water!!! Either way gh should not hurt, good luck bro..

Something is seriously wrong if your injections were painful with bac water. It's not the bac water causing the pain it's whatever's in your growth hormone. It's definitely big growth hormone tho. I been injecting gh multiple times a day for a long time now and never felt even the tinyest bit of pain.
