I beleive the level 3 dose for amanita is about an ounce. The caps are more potent of course and some people only use the skins of the cap. you can also buy the extract resin thats like 10X. so theoretically it may take 3 grams of 10x for level 3. dont forget the mushrooms need to be boiled for like 15 minutes to turn the ibotenic acid "poison" into muscimol "the stuff you trip off". for the instructions for astral travelling ....... do the programming with hands method as explained in an earlier post and also try this...... when you wake up in the middle of the night or early in the morning grab a quick cup of coffee .... this helps a lot because it creates a chemical reaction in your brain that will allow you to pop out. next lay on your back and just relax your body while keeping your mind alert. you dont want to go lucid because then you will slip into dream mode. your body will become numb from head to toe but keep relaxing your body. all the sudden you will feel kinda wierd but try to sit up. sometimes you will feel stuck like you cant move but you have to overcome this and once you do you will be able to sit up and look down at your sleeping body. when this happens I like to go to the window and put my hands through it like a ghost and it is really neat because you can feel the texture of the atoms of the glass enveloping your soul. then I will fly right through and just go flying around and stuff. one of my favorites is going at high speeds right through buildings. I have even gone right down through the ground like it wasnt even there. once I controlled both my soul "me" and my body. it was wierd as hell. another cool thing is 360 degree vision all around you. some of my recomended reading is any of the Seth books by Jane Roberts, "You Forever" by Lobsang Rampa, any of the Monroe Institute material, and any books you can find on Eckankar. the religion of Eckankar is like 10,000 years old with the books "The Shirati Ki Sugmad" as its bible equivalent but 8000 years older. But I find the Seth material the most fascinating because it is about the nature of reality from the standpoint of a bieng from other dimensions that have never been human. I started reading the books and once I started I couldnt stop untill I read the whole collection. My mom has always been into that stuff along with my grandmother and she got me into it from a young age.
most importantly above anything you have to believe you can do it
good luck bro I hope you get it
