I was just wondering, say if I have a real intense sparing/grappling session(s) and I went into it fasted prior, ( or in some cases after a ULC meal ) Would it still be a bad idea to have any a PWO shake afterwords ? Right now I have ON gold standard whey that I just use PWO after weight training days.Pre training now a days is usually coffey + creatine. PWO creatine + water
