I'm glad I can motivate you with my posts. Just don't follow my lead when it comes to my beer-fueled escapades on nice summer days. ;)

I take creatine (Creapure) myself every day. I haven't noticed any immediate benefits so far, but it is one of the most thoroughly researched supplements, and I don't think you have to worry about any negative side effects. Creapure creatine is so fine that your kidneys shouldn't suffer from residue buildup—unlike with coarser, less pure, cheap creatine.
