I agree with Irish. If you really want to know the answer to this question, and it definately is a legitimate question, then there are better ways to ask it.
Twitched asked a similar question, but in a much better way when he started posting here, and got much better answers because he was not accusatory with the question.
That being said. It depends. If you are naturally five foot ten, and 300ish, and can run a 40 in under 5 seconds, then you are naturally extremely fast and strong, and sure, you can get to those types of numbers clean, no doubt about it.
However, if you are under 200 lbs as you ask this question, and especially if you are not especially naturally athletic then the answer is that you may ever get there no matter what you take.
But I don't know of anyone personally who has hit the kind of numbers you have asked about clean.
