Your only gonna hurt yourself bro, even more so Im not gonna let somebody through who could possibly go to combat with my brothers having cheated, and now cant perform upto standard when lives are on the line. They dont sell juice in the mountains of AFG. If your gonna do a cycle, wait until your through the training, so you can build on a base that you and everyone agrees you had. Otherwise you, and everyone in your class will wonder if you could have made it without sauce (mental asterisk).
Besides, nearly everyone has the physical skills to make it, but believe it or not the biggest, strongest, guys will go away the soonest. You cant train mental toughness or pushing yourself to near death. I saw a guy die in training due to heart complications on a run, it isnt talked about much in the community, lets just say if you were even caught with creatine after that you were going home.
Lastly, have you ever been around actual Tier 1 shooters? They are not big guys and very rarely do they weigh more than 200 pounds. Believe it or not on an 2 mile swim, a 6 mile run, or a DA through the streets of Iraq when the temps is a, no shit, 117 degrees with body armor and a helmet, extra muscle is not your friend. Not only that no juice in the world is gonna make you any better of a gunfighter, and in the end thats all you really are.
I do mean to preach but I get tired of seeing guys who think they can cheat there way into something you really dont want to cheat. Its as much an honest assessment of yourself in combat as a person can get, not to mention in all likelihood you wont make it. The attrition rates are hovering between 75-85%.
