I like to go with 5g of taurine, and 10g of leucine. Parachute the leucine though, because its not water soluble and gets stuck to the sides of the shaker cup. Parachuting makes for no waste. Work into the leucine slowly, as some report bad gas(odor and volume) from it over 4g. Ive used 20 to try to help with sleep, and had no problems though.
