So I just pinned myself for the first time 250 mg test e. I went through 3 needles lol. Anyways, I tried twice in my left arm the first time it didn't hurt just couldn't get it to come out, then the second time I went for it I still couldn't get it to come out, and my left arm is hurting what is that from? I finally got it with ease in my right arm first try or third lol. Thanks for the help.
