Atlantis are the stronger of the strains, I bought 20g of tampanensis truffles from the internet, and after a week of doubt, they arrived, and even more surprising, they fucking worked, ended up tripping on my own at night, due to the lack of human contact I got pretty confused, but brought myself out of it and had a fucking ball, took a shower, turned it off and stood there for about an hour watching everything going on, then decided to get dry, then just rode the trip til it faded. Definitely worth getting some.
