If you are all natrual..... I'm jealous of your genetics
Anyway, if you are 8 weeks out, you should consider waiting = and staying natural for your first show...... to see how you do, and get some experience.
afterwords, as soon as you start hitting the juice.... you're gonna be huge!.... but you'll never be 'natural' again.
Yeah, stay natural for a while and do a few shows! A friend of mine just competed and she is natural and although most of her competitors were on juice she still placed 2nd and 3rd in the two shows!
