I found for myself, that it all depends on my diet. As a natural bodybuilder I can take my physique to pretty good size and muscularity if I consume a lot of calories and train heavy. I had a job in Kosovo for two years, where I was Recreation Manager for the US Facilities throughout the country. I ran the gyms and rec centers. I lived on base and had access to several 24hr dining facilities and all the food I could eat (for free) everyday. Quality food, I might add. I took absolutely no drugs and managed to put on some good size and increase my strength pretty well. check out these pics from 2001 when I was in Kosovo. The great thing about being natural is you don't have to worry about the roller coaster of up and down size. I've been able to keep my mass for.......well, for as long as I can remember.
