Not to be an ass, but why do people put so much emphasis on "what" the pros take...I can tell you this, 99% of the general bodybuilding population could take EXACTLY what Kevin takes, and none would look as good...I am good friends with 3 different pros, and they take things just like we do, i.e. Winstrol (winny), primo, clen, halo, all tests, slin, gh, etc. The separating factor is simply this imo:
1. They have supreme dedication, where most of us bounce back and forth with diet, training, sleep, supplementation, and CONSISTENCY.
2. Genetics, genetics, genetics...need I say more?
3. Time on task - which allows the maximum intensity to be of maximum benefit. Also, the pros have the greatest minds in the sport surrounding them monitoring their every move...
Simply put, I believe that bodybuilding is literally their lives compared to just being the obsessed habit that most of us make it. This is my $0.02, and I hope I didn't piss anyone off, but it seems like all I ever hear is, "I wonder what so-and-so takes"...
