I'm currently using the get shredded extreme guide for this year's contest prep. It's working great so far. But was curious about what carb source to use with my post workout shake. I've been using oat powder (I toss oats in my food processor) and total iso pwo. Then eat some chicken and jasmine rice about an hour later. Just curious if I should use dextrose in place of the oats, or if it really matters? Thanks for any input.
