Devo, how scientific do you want to get? Are you measuring supplement macros? You know fish oil caps have fat in 'em!
Just sayin' you're getting too crazy about percentages and this and that.
Sounds like you want to look like Mr. universe all along the way to being Mr universe, and even the actual Mr universe can't do that. It's not a science project. You have ebbs and flows.
Define a goal. weight and look. Or whatever. Then work towards it. See what happens and adjust as necassary.
DO NOT try to be perfect from the first day. Find your Mr. Universe form,not someone else's then hone it in.
I am Anton Zdravko Martin!
