This sounds silly but the best creatine product I ever used in my entire life was from Wal-Mart. The ultra advanced/performance whatever creatine...fruit punch with some bcaas. 15 bucks for 30 servings post workout. Good stuff. That is just me though hehe >.<
All depends on what you want to do with it. Swallow caps? Enjoy it in a drink? Add to a protein shake?
I've found creatine monohydrate to be tried and true, I don't even mess with other kinds, and I always make sure it's "creapure."
AX German creatine is good for non flavored, and my all time favorite flavored creatine matrix is Creature. Tastes amazing! Especially mixed with RecoverPro BCAA's.
