re: Teen supplements & creatine use

Yea, I think you have that right. ON is a solid company. I don't think their creatine is creapure anymore, but they are still a quality company so their stuff is perfectly fine and tested. I'd assume the other ingredients are for what makes up the capsules as well.

It is essentially a purity standard at this point. Creapure basically certifies that whatever brand's creatine is 99.9% pure. It is a german based creatine and they have somewhat applied their beer purity laws to creatine for lack of a better way to describe what it means.

There isn't any added benefit to creapure other than certainty around its purity. There are still very good creatine brands that aren't creapure, but you just have to do some extra research because they will generally get their creatine from China and they can be not so pure . ON is a good company though, so their stuff is still good.
