I started at 200mg/wk, after 3 months I reduced it to 180mg/wk. Had BW 3 months after that and it was 1056 at my low point of the week. Doc reduced me to 100mg/wk and I've been on that dosage for a few weeks now. I still feel pretty dang good but will give it 3-4 more weeks before more BW. I'm still trying to decide what feels better, its different... but in a good different way.
I think the bottom line is you have to experiment at different dosage levels and give it enough time to compare how you feel. And also keep it within a reasonable physiological range. If you feel good at a lower level, it's probably a good idea to not run at super high levels.
Btw, if the shots are causing you pain afterwards, try a smaller gauge needle. I use a 25 gauge 1" needle and rarely feel much effects during or after the injection. When I first started, the nurse was using a 22 ga. needle, 1 1/2" long and I would feel sore for a day or two afterwards. Not that bad, but why use a fat needle if you don't need it?
