Wow, all these people here and no one knows any pros's??!! I'm good friends with a very well known, very gifted pro. The genetic gifts aren't just in the ability to grow muscle. They are also the ability to process food and he isn't affected by partying like us mere mortals. His stacks aren't too crazy, but do include test all the time (3 grams in the off season) 10iu of GH and he just got into IGF (he likes to stay around 40mcg a day). He has helped me prepare for my shows and I help him. But if you were to peg it on anything it is 90% god given genetics.... trust me.
Precontest is much like what we do.... even dosages. He has the same problem as I do. He leans out too fast. But he is a much better dancer.... hint hint and last I saw him (2 weeks ago he was 265 at 5'8-5'9 5 weeks from a show. He had only cleaned up his diet and cut out dairy and his skin was paper thin.
