I'm going to have to light the candles and dust off the biochem tomes I guess. As I learned it, the Creatine Phosphate energy pathway is a different mechanism than he Kreb's cycle, which is what is going on in the mitochondria to produce ATP. This article seems to say that creatine is part of the kreb's cycle, which is isn't. If it were, it would likely have some benefit for endurance athletes, but it doesn't.
Or am I just spouting gibberish?
Edit: Oh, but as an update on my personal creatine experience, it seems to be working. My lifts are still going up, and my muscle measurements have jumped a lot faster than they should from just building more protein fibers. I do seem to have a tight feeling in my forehead a lot, last night I had a mild headache. It could have something to do with the creatine and water retention and stuff, but thankfully I haven't had another migrane.
