None of those have anything to do with training or supplementation. What they realy have to do with is bad habits, poor choices, a lack of dedication and different priorities.
I am training a guy currently who is married, works two jobs, is finishing his masters, and has several kids.
With good diet, training, dedication, and no supps what so ever- He is making great progress in strength, and a posative shift in body composition.
Don't get me wrong though. I'm not trying to change what you personaly believe about you own use of supps.
The take home message is that supplementation is only supplementation. If the other factors in the developement of a potential athelete are missing or lacking, it won't matter what a person takes. They will not develope to any where near their potential. Supplements will not help that.
