When it comes to creatine, I keep it basic and just go with the cheapest CreaPure. Also micronized stuff is better, raw creatine gave me bad stomach cramps. If you want to get fancy than add Dextrose and ALA and make your own CellTech. Kaizen makes a good, cheap creatine transport that does all the mixing for you. After reading about TRAC, I may add Arginine to my custom mix. And reading about glycerol fuel, it looks like it may be a good addition to the mix. May help with some of the "smoothing" people complain about and superhydrate the muscles. Sorry, didn't mean to sound like a commercial. Also make sure you are drinking enough water(1-2 gallons daily)... but this should be a given with anything.
JG1, why do you want it it to carb free? You need carbs for creatine. If carbs are your worries, than take it post work out.
