Awesome post. I always thought this. All these bullshitting tossers who say there natural like the Musclemania guys, Tito Raymond, Stan McQauy, Skip, etc are talking horseshit.
Skip competes at like 215 or so at 5`10. Like you said If he was natural, he would juice and be up to 240-250 on stage and be a top pro.
I knew a guy once who was in awesome shape year round at 5`8 he was 215 at 7-8% with 19 inch guns and said he was natural. If he juiced he`d be a top pro on stage at 225-230 for a 5`8 guy. I hate bullshitters.
