I've gone as much as an inch higher up from there. Used to get some pain and soreness there, but that was more because the IGF was suspended in BA. The IGF MC sells now is in AA which is relatively painless--just the part where you stick the pin in is the part that can hurt now. I wasn't sure the stuff was working with the AA at first because the BA used to cause the muscle to immediately swell up a bit besides the soreness, but in a about 30 min. I got the usual signs the IGF was working like the tightness in the chest, etc.
