hmm old ass post, but i never did follow up until i received a PM today...if anyone's interested:
it wasn't concentrated. took a drop, another, 2, another 3...drank some jager, still nothing...finally just poured some of it into the vial cap and drank it like that. At that point however I tripped tits, wasnt able to see the ground, imagined myself sitting at another bar, before snapping back to reality. One of the heaviest ever, but not like ZOMG OMG i'm on like 20 tabs. Maybe 2/3 equivalent or so.
Thanks for all the suggestions!
