Yeah, what these guys have said is true, generally, at the least for the Army, they do not test for AS but they can if its use is suspected. It's pretty much at your commander's discretion. But, I knew a lot of guys who did cycles regularly while I was in and they never ran into any problems so you'd have to use your own discretion, but it would be a waste to do a cycle immediately before basic training, and yeah Ft. Benning is a fuckin hell hole all year round but especially in the summer.
