If you want to win you must have had a good physique previously, then took about 6 months off ,then starve yourself and deplete everything for a week,then take your before picture, then after that take shitload of drugs(steriods,gh,insulin), then make sure your cut for your after photo(use dnp, and diuretics). Then after all that you still might not win or even be one of the lowest winners(the people who get a 3 month supply of free supplements or whatever).
The people in those competiions are not neccesarily natural,some of them may be. I remember watching bill phillips stupid video and at the beggining he was at a bodybuilding competion,he made views believe people in those on stage competions are on juice and that a 3 month competion is a way to have a drug free competion, yea right. Although both juice,It is more likely the opposite, a 3 months compeitions would be a bigger attraction to drug users versus naturals.
