I know this should be in the supplements forum, but this one gets the most traffic, and I'm sure it's still a good question to ask the people that come in this forum. Anyway...just wondering if anybody's bought creatine from here: https://www.creatine-only.com/pfanstiehl.htm Supposedly they are the only creatine manufacturer that maintains a Creatine Drug Master File with the FDA. Any thoughts?
