300-350 is where you want to be. You want to be over a 1000 test level on a cycle. Typically your gonna be about 4-7 times the amount of test you put in, 4x being on the lower side. It depends on how your body uses the Test. I know my body is usually 4-4.5x the amount of test I put in and I ran 300-350 on my last cycle putting me In the 1100 range.
