spidey. if you get off creatine, nothing special will happen. You might lose a few lbs, but it will be water. Your strength might suffer a bit, but that's just a little. Most people feel a lot weaker when off creatine, but it's mostly in their heads.

P.S.: If that's you on the left in that pic, you look big.Props. But i think your b/f is around 15-16 %, not 10-12...
Stay strong and healthy.
