I've had what was sold to me as 'Ox blood' too, it was crazy mad rocket fuel that kept me up for about 3 and a half days, and completely twisted my perception of everything the first 36 hours buzzed by without me hardly noticing, after that I entered some kind of different realm, nothing seemed real, nothing seemed fake, I think its what is reffered to as spun, me and my girlfriend finally went to sleep on a tues afternoon after taking on sat. I woke up 2 days later, I'd been fired from my job for not showing up for the last week and not calling in, my g/f had re-arranged the entire house and later kicked me out, then I got the worst comedown I've ever had. I would honestly kill the person I bought this off if I knew where the fuck he was. My experience on it was fucken terrible.
