WOW looking at the trip calculator It said I only hit the second platuea, for me the 2nd platue is 113 to 288 mgs, And i took 225mgs. So right in the middle of 2nd platue would be the best for a first time user. YOu will expirience out of body ,and also audio hullicinations at 2nd platue well at least i did. And it will be the most euphoric time of your life!!
