Hmm, I worry about the doses listed. 1.6g of potent caps will get you right fucked. If you haven't done them before and are planning on having a couple drinks and socializing etc I recommend no more than 0.5g (for at least 1.5hrs) then re-access from there.
Different mushroom species have different quantities of active ingredients. Describing the dry weight of a mushroom is really only a secondary measurement of the active ingredients. Elsewhere on the website they compare 2.4g of mushrooms to about 100ug of LSD. So 1.7g of mushrooms would be equivalent of about 45ug of LSD, and the micro dose range of LSD is 5-25ug. Tripsafe is attempting to describe a light dose, whic…
IIRC, the amount of psilocybin in a mushroom is sort of fixed at a certain stage of its growth, so picking them when they're larger can just diminish their strength by weight and mess up what you think is the dose. As with most drugs, I find batching them together, say by grinding them all up in the case of mushrooms, and then taking small doses to calibrate the batch strength, is the safest way to go.
I usually recommend taking your mushrooms and blending them up in, say, OJ, then pouring them into ice cube trays and freezing them. They keep quite a long time that way and it's pretty convenient.
