25...160 @ 5-9 @ 11%+ BF ?
no offense, but learn how to train, and eat properly first.
i started at the gym when i was 18..at 150lbs..didnt know a thing, and in 2 2/3 years i got to 230lbs 100% naturally.
now while my dedication might have rivaled yours, i am quite certain that you could attain 180 if you ate and trained properly.
the avatar picture to the left is me in my first show, 100% natural.
i decided to try a cycle 5 weeks ago after 10 years of natural training, and quite honestly its not all i expected. its not even close to a magic bullet. and from my experience, actually makes it more difficult to remain truly in-tune with my myo & biologic state.
Without knowing what to eat, when, training properly and allowing growth to occur (during rest), you will get no where - Steroids or Not.
Possibly hire a trainer to evaluate your whole "plan". Without a plan, you plan to fail.
