This dose, i dont know if i decided to use it out of brave stupidity, sick curiosity, or just plain boredom, however in the words of Illidan Stormrage "You are not prepared!". Krokodil earns its extreme rating and then some. During the 1 hour trial that is Krokodil, i felt a cycling of pressure on my chest and skull, moments of extreme pain, reminiscent of breaking bones, between the pain and pressure, i felt confusion loss of body orientation (felt kind of like my arms and legs were separate from my body and moving around), i also felt numb and euphoric, and sickly enough a strong feeling of pleasure. after the dose ended i had a strong feeling of nausea and i continued to feel numb and disoriented for about an hour. In my time using Idoser i have felt many experiences, this by far was the most powerful dose i have experimented with, if you are seeking something more, this dose (at least for me) delivers and doesn't let up even after it finishes 5/5 recommend for experienced users
