Ontop of the rarity factor is the (il)legality factor.. I liked 25i quite a bit, and with nbomes being recently banned in the UK, and now in many states, it only follows that the sources of these chems are soon to dry up. So even though I haven't tried 25c, 25b, etc yet, I still want to get a decent stock because I feel like in the next year or so we're probably not going to see them anymore.. this may be different for me here in Canada, and I feel like china will still make them, but the chances of them making them will be diminished because of lower demand.. Another thing is the Benzo-difurans, they became big in the UK and were subsequently mostly all banned.. they're legal here, and legal in the US as far as I know, but they never made their way over here, and all the vendors it seems were UK based, and obviously they pulled them.. so it seems no more of those drugs for ANYONE.
