To illustrate what people are saying. 175mg a week gets you to 800. 140mg a week gets me to 1000-1020. If that 800 is trough level are you injecting twice a week, or once? Switch to twice if you are doing once, and your peak will rise from 800, as the peaks are lower, and the troughs are higher when you inject more frequently. For me it was a mathematical equation. When I was around 700-800 at trough I divided my test level by the mg of test I was taking and then multiplied until it was around 1000 and it was pretty spot on.
