Mate - the prototype of the class (etonitazine) was something like 1500 x morphine in potency in animal models.
But the problem is that 'nitazene' is a (inexact) description of a class of compound. So you still don't really know what you have.
So nobody can POSSIBLY tell you what an appropriate dose. I know etonitazine turned up in Russia in the late 80s and there were a LOT of deaths. Their answer was to tap the tobacco out of a cigarette, mix in the drug, carefully repack the cigarette then take a toke and pass the modified cigarette to the next person in the group. I assume this was so by the time the cigarette came around, a user would know if they wanted more.
I know they nicknamed it 'The Chinese Dwarf' although it was in fact being produced in Russia. I don't know if something is lost in translation and/or the vendors were conducting a 'false-flag' effort to suggest the stuff came from China.
Last I read there were 37 identified homologues. Some are only a few times more potent than morphine, one was some x 6000 morphine in animal models. That is a truly huge range.
I mean, the awful truth is that some users will let someone else test the gear but what annoys me is if the unlucky punter goes blue, the other users will often scatter, negleting to call the emergency services. It IS extremely dangerous for all the reasons I've given but the last one is that it may also contain another class of opioid and that could be something we don't even have test kits for.
