Clen question including taurine

Hey guys, im about to start clen (ventipulmin pump), and i know that taurine 3-5 g must be taking with it, along with 300-500 g of potassium. However in Canada, i was told the fda banned the selling of taurine... although its sold over the counter in the U.S. go figure. I did find a place that had taurine powder, from a company who sells aminos in powder as well, but i wanted to double check that if there was a difference between the powder and pill form before i went ahead and bought it. I belive their serving was 4.5g per tsp i think, anyhow let me know what your thoughts are guys, or if you know where i can taurine in pill form in canada (toronto)

Thanks bros
