The answer is simple -- get a blood test. I always see these arguments about whether to use 250 vs a gram in a cycle. And everyone grows off different amounts. Bottom line, get your natural test level measured. Mine was very low to begin with (around 220), so I grew like a weed on 250/omna week. If your already one of those mesomorph guys who has natural levels of 800-1000, you'll need more. Sure, this might not be the only factor in how you respond, but it is one that is overlooked by many people. Best of luck to you, and remember that diet is of extreme importance!
