Not going to happen for 20+ years! By the time a BB turns pro his receptors are about 95% burnt out. This gives him about a 3-5 year window before he start to decline. Also couple that with no one goes "off" anymore. A good example if Phil Heath, he has been a pro for about 4 years now and his mid section is already out of control. At this pace he will be washed in 3 more years.
oddly enough Dexter has the right formula for longevity, I am not saying that he is the best, but he is gradual weight gain was the way to go.
