I just shot up a half ml of test 250 into my friends right arm. when i pulled back on the plunger there was no blood in the syringe so i went ahead and injected the half ml. right when i pulled the needle out of my friends arm he said he dont feel right then he rolled his head and closed his eyes, then his head fell to his chest. I was shaking him and asking him if i should call 911 and then he slowly came to awhile after. after that he felt like throwing up and he was sweating alot. can anybody tell me if thats normall?
