I'm a fairly new user of steroids. I have a friend that has been using steroids for years. He has some connections and I buy directly from him. I ordered some 1" 22gauge needles per his advice. I had him stick me with 1.5cc of Test on my right side of my glut and 1cc of deca in the other, this was on Saturday. It's now Monday and my lower back is killing me. I hope it's just some sort of coincidence and nothing serious. Has anyone had any experience with this sort of issue? I'm also 37yrs. old, am I to old to start getting into this?
