250mg of testosterone and 350mg of testosterone per week are going to suppress you just as much as 500mg of testosterone per week. If you are going to run a first cycle, you might as well do it right. 250mg of testosterone per week is not much more then a TRT dosage. You aren't going to notice much from it.
Here's what I recommend:
Weeks 1 - 10
testosterone e or cyp 500mg/week (inject 250mg twice per week)
aromasin 12.5mg every other day <- very important to prevent against estrogen related side effects like gyno and water retention.
After your cycle run the perfect PCT protocol:
