This is a very old topic - but as one of the admin I must share the sad truth: after the communities (overall) got more and more fragmented, split in smaller groups, and after 2 years of very hard work trying to give a decisive change to RC Opiod scene - to make it again meaningful, harm-prevention centric, and filling a gap existing since YEARS and it's just incredible how any manufacturer are missing a huge, even legal business opportunity - since it's plenty of easy enough to synth, exceptional receptors affinity, 15x-35x potency RCs opioids.
All that's on the scene in the last year killed the scene (other than many people) - Etonitazene analogues ("Zenes") are probably the worst class they could have released. Not in terms of "efficiency" - the various analogues - the working ones ranges from 70x to 250x - an incredibly high potency (Fentanyl HCL is 50x) - but sadly a potential totally wasted. Indeed, they are very cheap, and for over 3 years DEA did nothing, despite knowing everything, DNMs banned all fent listings (even the pharmaceutical ones!!!) just because a scapegoat is needed (officially it was because there was SO MANY scammers and desperate people, that the ban could have had legit reasons many years ago - but now it's since years this ban is causing LOT MORE victims than harm prevention, fent is sold anyway but cut and with unknown dosages and description, putting at risk so many people with a low tolerance!).
Zenes other than the huge mistake of being sold on clearnet, causing a huge wave of death fo opioid naives, got such strong analgesic potency but a very poor recreational effects. Compounds of 15x (Acetyl-f) or 25x (Fu-F) and many other, with much lower potencies had a way better, more euphoric and body-warm enjoyable feeling, and not being caustic or else. Zenes will TOTALLY DESTROY your tolerance withing weeks, and even at the third day your needed dosage will raise exponentially. They are great compounds if all you seek is strong sedation and nodding. But the price to pay is - few weeks of daily usage, even at low dosages, means MONTHS of waiting before restoring a decent tolerance. And Users who counted on them, (they are all officially banned in USA since Jan/Feb 2023), now harder to find - and used them for 1-2 years, with a tolerance that could kill an entire building - the withdrawal was brutal, if people think Fentas WD is bad, Zenes is way worst! And the most annoying thing is not having anythign to taper down, if somebody seek to do it willingly (the other rc opioids are < 1x morphine potency, and the meds opioids, the stronger is oxymorphone, let's say 4x being generous and incredibly hard to find and expensive and won't do any effect, if your tolerance is 150-200x). So this really sucks not having anything in the middle ground. Detox with Bupre or Methadone is the only way, but the WD will be a big bad beast even on psychological side.
I don't talk because I read it, but because I lived it in first person.
Long story short, despite there was some private released of very good opioid RCs, with legal status, and a potency between 10x and 80x (no guinea pigs, componnds with lot of data and literature behind), tested successfully from a few hundreds persons - as long as zenes are around, the community don't really care. And the person who was leading this project and having such skills - opioid chemistry is definitely not the simplest one - left/abandoned the project, being a big turn-off for all the hopes to restore the scene.
At the current state admins of the reddit sub or OD forum decided to take a break, and see how situation will develop when Zenes will exist the scene, or at least intermediate potency new classes will be manufactured and available WW as legal RCs.
I'm really sorry to bring such news - there will be still researched in some private groups - but there are not plans otherwise to re-launch OD forum (despite everything is basically read), because there is no real purpose that could be achieved, seeing how the reddit sub became a junkyard was enough.
Thanks for your time,
