That's states that you'll see a 50 fold serum creatine concentration 2.5 hours after ingesting 20g's of creatine. One argument is that your muscles cannot absorb it. Another argument I've made is that having "free creatine" in your bloodstream while working out would efficiently replenish ATP, above ATP stored in muscles.
What am I missing? I'm about to start ingesting 20g's of creatine with breakfast 2.5 hours before I work out.
