I agree on test only to begin with, but not cause its simple, but cause the more AAS you have in your system the greater your myostatin expression will become, myostatins stop growth so you don't end up with one arm that weighs like 400lbs or whatever.
The more you can get out of the lowest dose, the longer you can abuse them for without stalling or fucking yourself up.
If I knew what I know now when I was designing my first cycle, I'd use proviron also. It'll increase your total free test and make your test hit harder and make you feel really good about everything.
For dosing, as I'm too scared of needles for bloodwork, I'd start at 150mg a week of cypionate or enthanate and work that up by 50mg a week to whatever you feel comfortable with up to 600mg, which is a good rough estimate for most people where the law of diminishing returns kicks in.
Proviron dosing is generally around 50-75mg a day.
Around 250-300mg you may start needing an aromatase inhibitor, possibly sooner if carrying excess body fat.
I gauge my hormones levels by how my dick is working, if it's hard to cum (and I'm sweaty at night) I have low estrogen, so I take less arimidex. If my knobs kind of soft and I'm not really all that bothered I probably have high estrogen, itchy nipples are a telltale too. Then I take more arimidex.
All that being said, what that cycle will do depends on your diet and training.
