UPDATE: After seeing this report in multiple places, I decided it was appropriate to come back and update it, as well as move the detailed reply up to the OP. I've since tried 4-FIBF from multiple sources and none compares to the original. The experience is quite similar with the newer 4-FIBF, the main difference pertains to the dosage. The newer 4-FIBF that I've gotten comes as crystals rather than a powder. This 4-FIBF requires a dosage about 4x higher than the stuff I originally got, which came as a powder. I'm not certain of the difference, my guess is that it's a different salt, but I can't be certain. I've tried probing vendors so that they'd ask their suppliers but nobody can supply me with a clear answer. So if you're lucky you'll get the stronger 4-FIBF, but if you're getting it as crystals, chances are it's the weaker stuff. It's still a fantastic analog in my opinion, but is just weaker than is implied here. Furthermore, the 4-FIBF that comes as a crystal is not quite as water soluble. You can remedy this by adding just a little bit of Propylene Glycol (PG) to your solution. With about 95% water and 5% PG you can dissolve a good bit, and increase the PG concentration as needed.
I am not sure if anyone is still interested in the topic, but does anyone have any experience with FIBF?
On threads like these there are
ALWAYS people who are interested. Anyone who sees it for sale or hears about it who googles it will see this as the #1 result on google, so even if people don't regularly reply, people read this thread all the time.
So I just thought I'd take the time to add my report, which you can find over on reddit
here.
The most important things for people considering 4-FIBF are:
1. It is by far the
LEAST recreational/euphoric opioid I have ever tested. People who are getting into this need to understand that this can make for a
VERY DANGEROUS combination. Since most people base their dosage on experiences with other opioids, they may continue to dose until they feel the same euphoria they feel on heroin or another analog of Fentanyl. I did this when I first got it, I took way more than I needed, and I ended up getting pretty sick, and still never felt anywhere near the euphoria of heroin or any other fentanyl analogs, even at lower doses. I think it's literally impossible to reach those levels of euphoria because the euphoria is so lacking with this analog. It might be a little sedating, and provides good analgesia, but if you're not addicted and not in pain, I would recommend staying far away from this analog because it could easily start a nasty addiction. This could cause much worse withdrawals when detoxing, but proper dosing could actually produce less withdrawals (more on that later)
2. It has
BY FAR the longest duration of any RC Fentanyl analog, including plain Fentanyl Hcl itself. I'd say it lasts about twice as long as Fentanyl.
3. It is very potent, almost equipotent to regular Fentanyl. Maybe even more potent, but the lack of euphoria makes it difficult to compare. My comparisons come from primarily from the dosages required to avoid withdrawal symptoms. But the duration also contributes to that. Since it lasts twice as long as Fentanyl, if it was equally potent, you'd need half as much to avoid withdrawal due to the increased duration.
So all of these facts mean that newbies should stay far away from it. However, if you're already addicted to Fentanyl, or heavily addicted to other opioids, it can have a lot of great benefits that are less scary than other Fentanyl analogs.
1. The price. Compared to even Fentanyl the price is about 1/10th to sustain a habit. Compared to a similar oxycontin habit the price is more like 1/100th - 1/1000th, so it can save you a lot of money. But beware, a cheaper alternative can mean you readily increase your dose because of your vastly increased supply for the same amount spent. This is why Fentanyls are so dangerous to start using.
2. The lack of euphoria. The other main reason switching to Fentanyls to sustain your habit is because they give less euphoria than the opioids that most people are switching from, primarily Heroin and Oxycodone. With most Fentanyl analogs you can reach the level of euphoria you're used to with Heroin/Oxycodone, but it requires a much higher dose, which drastically increases your tolerance, making it impossible to get that same euphoria if you try to switch back to Oxycodone/Heroin. However, with 4-FIBF you'll never feel that euphoria regardless of how high your dose is. So chasing that euphoria with 4-FIBF could spell disaster for your tolerance, but if you know ahead of time that you'll never reach it, and therefore don't try to increase your dose for the euphoria, there's less risk of increasing your dose due to increased supply and lesser euphoria.
Regardless, switching to a cheaper alternative regardless of the effects requires self control and discipline to not cause your addiction/tolerance to get out of control.
3. The lack of intoxicating effects in general. It also produces less sedation, less itchiness, and less effects overall, while quenching your desire for opioids. This allows you to avoid withdrawal while still remaining functional because the usual opioid intoxicating effects are downplayed, while your withdrawal symptoms also go away.
4. Lesser withdrawals - This is just in theory (
Note: I'm not an expert so this could be entirely wrong), but because the active effects are less pronounced, I'd imagine that when you are withdrawing from 4-FIBF instead of a highly active/euphoric opioid, the withdrawals would be less problematic. And also less intense because the duration is longer, although the withdrawal process would probably take longer as a result.
However, it's important to note potency. When I say it'll cause less severe withdrawal symptoms, I mean if you switch from heroin to 4-FIBF but use the absolute minimum dose required to avoid withdrawal from your regular heroin habit, you get used to that dose of 4-FIBF, and then detox from 4-FIBF instead of Heroin, the withdrawals would be less severe. However
BECAUSE the intoxicating effects are less pronounced, it's a lot easier to build a higher tolerance, so if you took twice the dose of 4-FIBF you needed to avoid withdrawal from your heroin, the effects you notice would be less than what you'd notice from heroin, but the withdrawals might end up being worse because the drug is actually more potent. So this is really a double edged sword, and requires very precise dose management to take advantage of.
With all this said, I think 4-FIBF makes the perfect alternative to Methadone/Suboxone for people who are looking to ween themselves off opioids, or just provide addiction maintenance. It's probably cheaper (even with insurance), far less inconvenient (no doctor visits required), and might even be more effective. So much so that I really do think that clinical trials into 4-FIBF could be very beneficial for addiction management/medication, but it's too bad that it's labeled as a RC and will eventually get the banhammer with no ability for any drug companies to do research into it unless they jump on early (which I'm incredibly doubtful of). The two hardest parts for opioid addiction management using 4-FIBF would be 1. Finding a good starting dose, and 2. Self-control & staying on that dose or sticking with a weening regimen.
Anyone seriously looking into this, I recommend putting your supply under the control of a trusted friend or family member so that they can dose it for you and make sure you stick with the plan. Another difficulty would be the really low doses when you're close to getting off opioids entirely. These would require a mg scale and volumetric dosing, I'd recommend dosing a large bottle, like 1L, then use that to fill smaller (~30mL) nasal spray bottles. So with a little bit of experimentation, find the ideal mg/mL. As a frame of reference, I was on roughly 10mg of Fentanyl per day, and 5mg of 4-FIBF per day was comfortable. I recommend taking your daily dose in 1 full 30mL bottle per day. So 5mg of 4-FIBF in 30mL of water per day is 5mg/30mL, or 1mg/6mL, or 0.166mg/mL, or 166.66mg per 1L. dose the 1L bottle, then fill the 30mL bottle from the 1L bottle. When you're adjusted to that dose, fill the smaller bottle not entirely full (~25-28mL) with the 1L bottle and fill the rest with plain water, until you're putting only a few mL of the 4-FIBF dosed 1L bottle into the 30mL bottle, and filling the rest with plain water. Additionally, I recommend using a bottle full of plain water, with 0mg/mL for at least a full day or two before stopping entirely as part of the weening regimen, but in such a way that your friend/family member is the only one who knows that it's entirely plain. The placebo effect from spraying something into your nose will ease a lot of the withdrawal symptoms for the first few days. I've experienced this myself, and it helps a surprising amount. Additionally, anyone looking seriously into quitting and looking for other ways to ease the process might want to look into ULD Naltrexone. I made a detailed post about it
here
I think I'll eventually make a more detailed weening plan combining ULD Naltrexone with 4-FIBF.
thanks for the concern.
