I gave a friend 2g dried of Treasure coast and 3g dried of orissa india. He split both strians in half and shared it with his pal. He said he was walkin thru the woods full of all kinds of colours and the grass was just millions of orange caterpillars. He texted me the next day asking me what the fuck i gave him lol (he had done shrooms recently before, but evidently they were not as strong).
Dosage will depend on strain, personally i would be really careful about taking large amounts of the potent strains,, it can really seem like what is happeneing is real, even if you are not in a dangerous environment, it can get throw u through all kinds of emotions and it might not be as fun as you think lol for example i had a treasure coast tea (about 1.5g dried aborts mixed with lemon juice) and i thought i had died and was being judged by the devil (not a real devil, it was my friend, he looked the same but it was psychologically real, he seemed to excude evil force) this was my first trip but im sop glad i didn't do any more than i did or i would have been stuck in that place for many more hours. Im pretty sure I was convulsing to some song on youtube, trying to sing some song that came up in my head, and mayb even orgasmed (altho there was nothin in my boxers, i jus have a memory of bein at orgasm) i also looked like id been steam cooked in a trolls armpit for 4 hours. So my advice would be to 1) look up the strain 2) know the dose 3) start low-average dose before doing anythin crazy lke 5g. but its your choice obviously.
