RCs Novel opioid, U-47700-Mega Thread and FAQ

I really hope THE REAL OBLIVION is okay, I think he might have gotten more U4.... Hopefully he's just with his loved ones on his bupe maintenance, stay safe obliv.

U4 ain't nothin to fuck with - raekwon.

hope you're okay, bud

Hey this is my first post here. I made this account mainly to comment about u-47700. I basically just want to confirm and sum up some things i have read here and what i have experienced with this compound. And what has happened to me lately. Fist off i have been on buprenorphine maintenance for a bit. Maybe since July of this year. But ive been on and off it for years. I was just incarcerated for a while for drug related crimes (like way, way too many others). About 2.5, almost 3 years. I got out and started fucking around again with opioids. I quickly realized i didn't want to go down this path again. I had a great job when i got out, thanks to being in work release for the last couple months of my incarceration. I had my own place, nice vehicle, etc. But yeah i messed around and paid the consequences. I got on bup very quickly to help stop this. But i messed around with some other drugs. Did some meth and came down with alcohol and benzos. Got pulled over and decided not to stop. I got charged with an attempt to elude and a DUI. I was on bup and went to jail. Spent a week there, of course with no bup. It really sucked. But i made bail and i got back on it. I got released and no joke within 10 minutes outside, i found a random person with suboxone at a 7-11 right next to the jail. us users know how to find each other : ) saw my doc the next day. Anyways I stayed on it and stayed clean but was never officially charged until a couple months ago, when i got the letter in the mail stating they were going to prosecute. So i knew i had to get off. I knew i wasnt going to have enough time to do a proper taper. So i decided to do what ive done before, switch to a shorter acting opioid with a really short withdrawal and detox off of that. Some might not understand but ive experienced sub withdrawal before. I made it 16 days and i was still detoxing. I don't want to go through that again. I work full time. It isn't feasible for me. Anyways i have a couple months left until im going back again to do my time. Just a year fortunately. which is like 8 months with good time. i thought it was going to be a lot longer with my record so i am very, very happy!

So, i had my plan to switch to something short acting. I was going to use poppy pods or seeds or something like that. Maybe even use painkillers. But this is all illegal or really expensive. Kratom was a possibility but i just didn't find it strong enough on its own anymore for some reason. And it's just too much of a mess. Too nauseating, and all that. So this led me to looking into rc opioids i have heard some about. I thought about fent analogues but they are still illegal and i have heard of people getting prosecuted. i can't afford to be taking chances like that right now. and i want to use sub to detox, but only for 3 or 4 days, not long enough to get dependent on it again. and ive heard sometimes even subs not enough to stop withdrawal from fent analogues. so that lead me to U-47700. Very inexpensive (especially with the fact there has recently been a sale, 50% off where i get it! and its already really cheap there compared to some others).

as for my experience with it so far- first off it works. it no doubt stops w/d. i didn't have a mg scale at first. stupid, yes, but it is what it is. i eyeballed. but i was as careful as i could be. I weighed 100mg and divided 10 piles. of course i do not recommend this at all. anyways i snorted about 10mg of it, after doing an allergy test. not long after wd was gone. here is what i have observed with this substance...

- I could barely tell the difference between this and hydromorphone. it has been a long time since ive done that substance but i remember it being quite similar. i feel it is more like that than any other opioid. at least with that ROA.
- It is very short acting. Keeps withdrawal away for almost 2 hours on the dot. Doesn't really seem to make much of a difference on how much i used.
- My vendors supply is very caustic. Maybe other suppliers are better or worse in this regard but mine is pretty rough. It burns, and it destroys the nose. After only a day or two, it really messed it up. Ive been doing it on and off for a couple weeks and im still having small amounts of blood come out along with mucus as ive had a slight cold. This has led me to switching up my ROAs although i only wanted to insufflate it.
- It is active at low mg, with my supplier at least it seems pretty pure. even with the bup tolerance, and i was taking a hefty dose of bup. 10mg at first not only relieved my wd, but gave me a rush.
- This stuff can be used however one wants. I have used it every ROA except plugging. i have never used any substance that way. just never interested me or seemed to be worth it. i must note that IV is slightly painful. There is a bit of a sting/burn for a few seconds.
- Tolerance builds quick. I have to take at least 30mg to get any wd relief. 100mg IV is as far as i have gone and its one hell of a rush. Somewhere between hydromorphone and H. Maybe with slighly less euphoria and very short lasting effects. I think if this had more legs, it would be much harder to tell the difference between this and h. Fortunately my mom was kind enough to get me an early christmas present... A milligram scale for this! very nice of her : ) so it was only the first couple of days of use with this that i didn't have a mg scale.
- also as stated before, this will cut through buprenorphine's opioid blocking abilities. I have done up to a gram of H and it didn't touch it. It has been many years since i even tried to do that as i know it doesn't work. But i ran out of U-1 for a couple days and had to go back on bup for a couple days until i got more. This cut through it like butter, like i didn't even take any bup at all. I was quite surprised. I heard that fent and analogues can do this but thats all i know of. Ive never done them.
- To sum it up, its a powerful but short acting opioid. With a tolerance, 10-15mg can give effect, but that won't last long. within just a day or two, more is needed, at least for me. It's euphoria is definitely there, just maybe not as strong as oxycodone or heroin, but it is no doubt there. It is very recreational. I don't nod until high doses like 80 plus mg. I can go work my job just fine. and i work construcion. metal framing, hanging, taping, painting, insulation, installing hardware, scrapping, all that labor work. and it's no problem. nobody even knows im on it. my usual doses are about 40mg. i basically switch from insufflation to iv. vaping works but i don't care for it too much. it tastes bad and the effects aren't super strong. one note, if i miss the vein when iv'ing, i don't get well. maybe i would if the dose was higher but it doesn't seem to happen. and btw iv and nasal doses are very close. surprisingly so. one thing i would like to do is learn to change the ph. i think i saw somewhere using muriatic acid? maybe someone can point me in the right direction here? i would like to just be able to snort it all the time. iv is too problematic with the kind of job i have, and everything else in my schedule. besides this switch and the fact that i try to make sure i don't get high when using it, i have been clean off all other drugs. i don't want to be high. i have been high on this a couple times but i don't want to be at all. i use as little as i can. i did have my one day experimentation phase but thats it. this is solely to stop withdrawals. i live a healthy life. im extremely active. i lift weights 5 days a week, even on this. im pretty big and in very good shape. i have plans to pursue a career in health and fitness when i get out. i really do want to be clean off drugs. im going to do everything in my power to not use when i get out this time. apologies for the ridiculously long post but it was my first one and i wanted to explain my situation. its just backing up what others have said but the more feedback we have the better idea people will have of what its about. i know a lot of people don't read all the fucking posts and they ask questions about this that have been answered by 10 fucking people. if this thread continues at least 10 more will ask all the questions myself and others have answered here. thank you community. btw i have until maybe late march early april until i go back. the plan is to stay on this u-1 for 1-2 months so i am dependent on this. then use bup just for a couple days to help a bit of the wd. then the usual detox meds for a week to help whatever wd is left. heavy benzos. probably clonazolam 5mg 3x/day like i have used before. with clonidine, gabapentin, baclofen, immodium, dxm, and some amino acids like dl-phenylalanine i have been reading about for wd to help produce endorphins. and keep lifting weights the moment i can even comprehend doing something like that again!

I did not, when it was gone, a lot of 1.25mg flub-lam pills and .5mg clonazolam blotters came my way and it makes it easy to save my rx'd benzos. That's all. Also, anyone who knows me a little here knows I tend to post in sprees and disappear for a while. It wasn't worth ordering more U-47700 until my dosage of suboxone is lower.

I think I'll be able to go from 10mg to 8mg a day on the 6th. I don't think any alarmism is worth speaking of regarding this stuff. What I got was 98% HCL pure from a very very good vendor not many people have access to. I'll maybe buy another 100mg sack when i'm at 4mg suboxone but not before. I mean, yes it goes over it a little, but not entirely. Not frustrating like with shooting up Dilaudid while on bupe though, nothing can be worse than that.
 
Far from the perfect opioid, its quite caustic and hard on the nose!

My experience with it is limited to oral as I also snorted about 10mg in each nostril and blew my nose before I got the drip as I began rethinking it, say about 3-5min after snorting. One notable factor is I am on MMT 170mg/day and I had taken 400mg methadone approximately when I decided to stop for 2 days to see how it felt. I didn't take any opioids the next day, going to bed at night I was thinking of taking some and eventually did take 10mg orally in a capsule due to the caustic nature, as an allergy test to be more at ease when the right time came. I would say 36-48hrs after my double dose, I began to use it strictly orally as I didn't want to fuck my body up like the notorious article on erowid where a group of chemistry students made a Demerol derivative or like the Krokodil horror stories, where people destroy their bodies in search for an opioid high. I began using on the mentality that if an opioid is pure without APAP or toxic binders, it doesn't harm any organs and its only downside being highly addictive. MT-45 was also quite sketchy also so you can understand my skepticism with this chemical. I decided that orally, capsuled, would be the only sensible way to consume this, as I have a phobia of needles.

After 36-48hrs I found 30mg+ doses necessary to get anything. I went for about 60hrs without methadone at the most, during which time I had used about 200mg, orally. During the entire time, even with smaller doses, much like Hamilton said I felt it going up but beside that it leveled off much like hydromorphone would, which I also didn't find very special or up high my preference list, though for someone that likes hydromorphone its should be interesting to hear their opinions. I will say one thing, while it wasn't something that broke through my dose not much will, even fentanyl wouldn't break through after 80mg. I didn't feel euphoric but I felt the drug and didn't get any sickness, was able to appreciate the legs, it has a long duration of 5+hrs orally and takes effect within 15-20min. The only time I felt somewhat euphoric was after I took 1mg lorazepam, that made me very sedated and I eventually went to sleep. In the morning while reading the reports of people's hearts stopping on this mix of benzos on top, I began to think they weren't trolls at all since my tolerance to benzos is such that 4mg clonazepam and 400mg methadone is ok, though could use 3x to get *fucked*. I needed about 60mg and then another 30mg orally after half hour from the 60mg, taken with the 1mg lorazepam. I only had slightly more than 1 full day to use this.

In conclusion, it really would be a perfect opioid or at least on par with hydromorphone if and only if it wasn't caustic...that we know about there may be lots of other side effects beside this that we haven't heard of yet. Right now the one guy has it for a very high price, think 400/g in which case, at least at this point knowing the little we know, its far from ideal. Even though I blew my nose before the drips the next day my nose was very hurt, bloody with a thick case of scabbing.....in other words a lot of damage from 1 single use.

Did zero damage to my veins, had no issues. It's cousin AH-7921 is known to be extremely caustic, and after pictures of people's inside of their mouth here after taking it orally, I said outright : if you do not weight and put this stuff in gelcaps and eat it, you're hurting yourself really bad.

The U-47700 was said here, elsewhere and by me not to be caustic like AH and that IV'ing it with the bacteriostatic water vials they give you in those injection kits we get here in Canada, plus the sterifilt inside the stericup (which is made to shoot pills and even works with shooting crack somehow) was safe. If I wasn't so full of food from the holidays (plus the alcohol and benzos), I'd link to the posts that made me decide the thing was pretty safe and not caustic like AH, some of them by XANAX XR himself.. But that's also why I still didn't take a chance and when I had that .1g in about 15 doses, I IV'd it, I always hated snorting except when it came to dilaudid, brand name, such tiny tiny lines.
 
New batch from my supplier is almost pure white, much, much less than the previous tan/off-white caustic U-4. I have no trouble eyeballing small doses and it doesn't hurt my nose much at all. I was making "monkey water" with the caustic stuff and that really saved my nose. I need much higher doses to feel much from this stuff orally so I've hardly bothered. The rush is short so I end up re-dosing and nodding out a bit pretty often. All in all a pretty nice drug for me tbh. Probably wouldn't choose it over oxy or even hydro but it's not bad.
 
J. Med. Chem. 12,944 (1969).

1 Step BUT if you add an o-Cl, it gets a lot more potent (but precursor price gets silly).

holy crap, look at the last synthesis fromt the patent when googling the name of that compound is almost exactly the same as U-477 MINUS the chlorides
 
It's pretty nice, according to my monkey. Not any kappa, with a markedly short duration, and a caustic nature (wrecks the sinuses, bloody sputum the next morning, even with a nasal rinse). All in all, pretty nice, though. Even the withdrawls, my monkey says, aren't too bad.
 
Welcome to bluelight, where we use the first person and don't drug our animals. That's just cruel.
 
So i'm wondering is there a cross-tolerance between U-47700 and Dihydrocodeine (or any other traditional opiates for that matter). I haven't used any DHC for nearly 4 weeks.

update:

It seems that U-47700 does not have a cross-tolerance with Dihydrocodeine =D

Especially the monkeys as they are one step away from us..... Who knows give them some LSD analogies and we might have ourselves a planet of the apes!

Speaking on the caustic nature does mixing vit C or citric acid packs the exchange give make a water solution asked nasally less painful? Asking with proper filtering IV less stingy?

Sounds like there is a good batch without the caustic nature making it seen more pure while the caustic stuff has an impurity leading to adverse reactions... Captain obvious to the rescue right?
 
Question about U-47700 and Suboxone.

I got some U-47 yesterday and went through like ~350mg in 24 hours, redosing every 2h and ROA being IV. Today when I woke up it was like 11 hours from my last dose of U-47 and the withdrawal was in full effect. As I had some bupe still left in my system (I dose 2mg and have been on it for 6 months, ROA insufflation) it wasnt too bad but bad enough for me to parachute 60mg of it and get rid of the w/d. I ran out of needles so I couldnt IV.

Now my question, if im looking to get back on Suboxone, how long do I need to wait until I can safely dose my 2mg of bupe without going into precip withdrawals from the U-47700 still being in my system?
 
To add some information to this drug it seems that U-47700 is metabolized in party by the enzyme CYP3A4. I use a medication that inhibits this enzyme and after I use it I have noticed the high definitely increases in strength.
 
Yes that is why it is a research chemical..... After reading reports of the MT-45 white hair and skin patch reactions from use deter me know from most opiate RC

I checked this out and grapefruit juice can affect the enzyme CYP3A4 and increase the bioavailability of certain drugs. From what I read it only affects the ORAL availability of these drugs.
