Truth be told, a lot of people wouldn't be big without steroids. Come off the juice with shitty training and a lacking diet - you will lose most of your gians. I've seen this many times.
However
On AAS, you can be more lenient with diet and training and still look decent. But to look amazing, that takes a little more work.
You can still build muscle on a calorie deficient diet as well...so yes the gear WILL put you in a more anabolic state with less food.
Just stating the obvious - and yes I agree with Ross. It's common sense...I've always preached and practiced a low dose, synergetic approach to AAS. I rely on training and diet to get the look I want. It's that simple.
Another thing, I rarely deny my AAS use. You can preach diet and training all day but some people will NOT look past your AAS use. At that point, all you can say is, fuck it.
