For all the people interested in this drug:
it's probably nearly impossible to acquire now. this is a good thing. there is no light there, nothing to learn, nothing to see. not only is the experience completely dysphoric, but the drug itself is very toxic - i injected it, and at every site i developed a deep abscess, golf ball sized, which had to be lanced and drained over a period of months. i have matching dimples in both biceps, concave areas where necrotic flesh was excised.
i firmly believe that dissociative drugs have the potential to awaken latent psychic abilities. mk-801 has the same potential, but it part of the downward spiral, the darkside. if you are experienced enough to know what is out there, you ought to know that some of it is bad, sick, corrupt and useless - mk-801 is just that. there are other dissociatives you can seek: memantine, dimemorfan, etc. go there instead.
