I say go all in.
Just like Terence McKenna says...
"if YOU pussy foot around, YOU may not get there... and if YOU don't get there, TAKE MORE!!!!!
Do not skimp the dose, people. There are legends here..."
I gave you a like with some hesitancy, meaning like acid, it's not like taking the largest bong hit you can, because you can't walk back from 4 grams or 2 hits of 4 way acid.
Acid and psilocybin are not drugs that you really should push to the limit (it can get scary in the wrong environment).
For all that have never tripped, take a half of what you think is safe, and then next time increase your dosage.
One big problem with hallucinogens is purity of the product, so no one is sure about the intensity of the trip.
I've eating batches of mushrooms that were different in the high, along with different batches of LSD.
I would buy enough for say 3 trips, eat a low dose 1st, and then the NEXT trip (don't eat more once you've started), bump it up if you weren't satisfied, or feel you can handle more.
Play it safe, especially for rookies.
