wanted to add.. I live in a small town. had to drive 40 miles to get xXtra clean..wouldn't have bought it if i had read here first! I couldn't find creatine supplements and I've been sick this weekend and didn't eat red meat except for a burger 2 nights ago. I want to use the dilition method...but have no creatine (too late now anyway) & not sure if it will last being that it could be end of day before I'm tested.
