Hey Cenzo, I'm still having bad injections from my current test. It's only 200 mg/ml, but it hurts like hell. I've heated it and that helps a bit, but not a lot. I just did one in the shoulder on Sunday and when it started hurting it was about two inches lower like you said. But, mine starts hurting within about three hours and doesn't stop for about three days. I've got a lot of this test, so I guess it's just something I'll have to deal with. If I stay on top of the Advil, I can keep the pain under control, but I'm tired of getting this from every shot.
