Just to clear out my bitcoin wallet, I got a vial of "liquid shrooms" (he sent me an extra too). Supposedly an extraction in alcohol, around 3g per vial. I haven't had regular shrooms enough to tell how similar it is but I figured even if it's just a 4-sub in solution I'd be alright. I tried one, it seemed pretty light but I may have fucked up my tryptamine tolerance with regular use earlier this year.
But to the op, definitely try to find out how strong your stuff is supposed to be before diving in.
