I know I have read on the blog and heard from other advocates like Tim Ferriss that creatine has benefits to cognitive function. I am curious if anyone is familiar with the available brands of creatine out there and what is the most bulletproof? What is the best time to take the creatine and what is the doseage based on body weight if you also want to utilize the physical performance aspects of the supplement? I have also heard it is best to cycle off creatine for periods of time because with prolonged use it can hinder your body's natural production. Is this true?
