Recently tried shrooms for the first time and was a bit underwhelmed, but not sure if I'm micro-dosing or what. Tried the regular variety and some other allegedly Thai shrooms, which definitely had a stronger effect. I tried a few stems at first, and then ramped up the dosage with slightly more 'visuals', but it's like I have to eat a whole handful or just let my body learn to process it or something.
From what I've heard (no real scientific data to back this) the stems contain very little psylocibin. And the dosage for mushrooms is surprisingly high. For run of the mill strains, I believe 3.5 grams is considered a standard dose. Which is still not a blast you off the planet amount, but enough to experience visual distortions and euphoria.
My last trip was about this much with another 1.5 set aside but I was blasted out of time and space and opted not to re-up.
It all depends on the strain.
