Welcome! DMT is amazing, and the easiest to acquire of the 3 on your wishlist. The entire extraction is ridiculously simple. Peyote is illegal (in the US at least) but san pedro and peruvian torch cuttings can be bought legally and both contain mescaline. Acid is awful hard to come by in a lot of places.

Hope you experience hyperspace soon, friend. It's a truly awe inspiring place.
