it's hard to imagine Cutler or Coleman on 750-1000mg. of test/week but hey anything is possible i guess.
Hard to imagine even with 15+ius of growth, and tons of slin?
I know a few pros, national guys, and plenty of local guys.
There is no correlation between what guys use, and what level they are. Some of the biggest juicers are the local guys, and some of the lightest users are the pros....of course, some of the pros use a ton as well, but the amounts are all over the board.
It becomes a point of where in the hell do you put all that gear?
How sore are your ass cheecks going to be on 5g of test a week? Even using delts, quads, bis, even lats, you're going to run out of spots to put all that gear pretty quickly.
