Worth noting the dose amounts vary wildly with the mushrooms and batches. The stuff I have (grown by a friend) would barely do anything for you at 2g. 3g was really the minimum, and 4g if you wanted anything other than feeling happy and high.
I've been lucky that I've been getting consistent potency (I think the online shop I buy from has had the same grower all this time). But other people have told me they've struggled with inconsistent potency. Super valid warning for others, thank you.
