I take 300mgs/week on average of test. Its a bit more than the standard most docs would issue (usually 100-200 week) but I like being a bit higher into the supraphysiological range for ideal muscle building/libido effects. 150-200 a week really didnt do much for me. Kinda was just replacing the level I was already at. (I'm 43 yrs old for reference). When i bumped up to 300mgs (and 2 10-week cycles per yr of 500mgs/week) I really started to notice muscle mass gains and insane libido.
I would ask OP if he was taking an aromatase inhibitor/estrogen blocker, like arimidex. Lot of guys neglect that and some Dr's dont even prescribe them, which baffles me. Injected testosterone will raise your estrogen levels, which in turn will make u retain water/bodyfat
