Altered State is a hidden gem! Their nootropic stack combined with microdosing products has been a game-changer for my productivity.
Great mushroom chocolate bars at Altered State! Delicious taste and the effects were smooth and gentle. Will definitely be back.
Great selection at Altered State. I was particularly impressed by their knowledge of functional mushrooms and nootropics. Very professional operation.
