I'm in the 175lb range and most of my other friends I've talked to who've had good trips on mushrooms are generally average in size. Generally we take 2.0 - 3.5 grams dry when we wanna have a good time. But I got a friend who's ~320lbs and he's never done mushrooms before, but he's interested. How many would you recommend he take for his first go?
I have a simple way to calculate that: one handful, one dose! It's personalized, so everybody's got the dosage needed without having "too much". Tiny people got tiny hands, so they got a tiny dose who fits them and same for stronger built people, it's perfect.
Ive been as low as 180 and as high as 270lbs and I always dosed in the 1.5-3 range, weight didnt seem to make a difference.
