Hi!

I'm very interested in 5-APB and just today I get 400 mg from a "trusted and official" ( 8) ) UK source. It should be fake 5-APB: the CAS number is 286834-85-3 and the chemical formula 5 methylaminoethyl-benzofuran. In a quick search, I realised that this CAS number is for 6-APB and the chemical formula (I guess) doesn't exist.

Fuck off, if you're gonna scam, print the label right!

I cannot analyze this compund until September, but it seems to be a lot of fake 5-APB around. Beware!

It's good you did your research beforehand though, that would have been enough to fool a lot of people.

I do hope you get your hands on some real 5-APB since it's a really nice compound, especially in combination with 6-APB.

is there actually a rational explanation for the good synergy between 5-APB and 6-APB? both compounds act as serotonin receptor agonists and monoamine releasers, correct? but what are the differences? which one has stronger affinity to which serotonin receptors, and how are the ratios of serotonin/noradrenaline/dopamine release?

5-APB turned dark black instantly with mandelin reagent. 6-APB tested sort of black but more darkish purple instantly. Any ideas why this is the case?

This isn't so strange, 5-APB and 6-APB have a small diference on Marquis reagent too. Sadly I'm not chemist :(

Anyone can tell me if 5 methylaminoethyl-benzofuran is the same that 5-APB?

No that sounds like N-Methyl 5-APB.

It's very poorly named, but that is 5-APB.

It's benzofuran with an aminoethyl and a very poorly specified methyl group.

frankly I'd boycott the vendor based on that trainwreck of IUPAC alone, but given the rarity of N-methyl APB and the fact that I've not even heard of 5-APB without the alpha methyl group I'd say they probably mean 5-APB.

when people say the 6-apb 5-apb combo is good, can this be interpretted that the combo is closer to mdma than either one separately?

Redbong

^ No, but it is a beautiful combo. The 5 giving your serotonin a good push, and 6 giving your dopamine a good push. They just compliment each other so well. I think 5 by itself is closer to mdma than the 5 and 6 combo.

6-APB is still mostly Serotonergic. The 5+6 combo is basically Serotonin + Serotonin. You're better off combining 6-APB with 2-FMA.

How do anti psychotics work with 6-apb? If someone been on them for only two weeks then stops for two weeks will still feel any effect or is it similar to ssri's & other anti depressants where you have to be on them for at least a month & take a another month or maybe more to feel anything

well 60mg/60mg 5-apb 6-apb combo resulted in something quite similar to an MDA roll. Or another way to think of is a combination of a MDMA roll with the beginning stage of a light mushroom trip, but more on the MDMA side. Either way it was neither as magical as a true roll or a true hippyflip.. nonetheless still a very nice experience. will try 80/80 next time.
talkativeness, euphoria, tactile, empathy, were all there.. just a little messy and not as profound.

Do you really know what would work wonders for your first appearance on stage touting 5-APB? You should grind the pellets into a fine mist, wash it with mercury, toluene, ammonia and molasses. Then, roll it back into lumps of bewildering clay balloon animals that are shaded with an intricate belief system in which you can attach to your arm while standing in line waiting to get in VIP.

The clay mercury chemical balloon animals constantly fisting you giving you the effects you always dreamed of!!!

Toodles!!

Just received 250mg of 5-APB HydroChloride salt. Supposedly, most of the 6-APB and 5-APB on the market is the succinate acid form, which (again, supposedly - can anyone confirm?) holds 40% more actual 5-APB molecules per mg. Been a long while since I've tried this one, so I'm quite looking forward to it. As far as I remember (from my early trials) it was more potent than 6-APB but not quite as enjoyable. Perhaps I'll change my mind, since the trials were based off an early synth.

Going by my own experiences and the release values for 5-APDB and 6-APDB the 5's are mostly serotonin releasers with a lot less dopamine release and don't have quite the stimulation or rush, while the 6's are more dopaminergic, rushy, and in general pleasurable - however 6-APB isn't quite as lovey as say MDMA imo and this is where adding in 5-APB works great as it adds in all the extra empathy and makes it a wonderful combination that feels significantly better than MDMA to me :)

I think the magic of the combination is that while adding a mostly dopaminergic stimulant like 4-FA, 2-FMA, Amphetamine etc to 5-APB would make something like a longer lasting trippier MDMA - this combination makes for both more stimulation than MDMA *and* a LOT more love, which is a wonderful thing to have :D

Also, I'm not sure why this happens but in my experience the length of the peak nearly doubles for me when I take this combination, from 4-5 hours to 8-9.

Mixing 5-APB with 2-FMA had less than expected results. It seemed to increase the stimulation but little increase in euphoria or other enjoyable effects. I wonder if this is because it is a 5HT2C agonist (limiting Dopamine and Norepinephrine).

HCl is 10% more potent per unit weight.

5-APB has a mass of 175 g/mol

Succinic acid (118 g/mol) is diprotic so one molecule neutralises two APB molecules to give a dicaionic salt. Mass (175*2+118)=468
468/2 to get the effective molar mass of 234.

HCl weighs 36.5 g/mol and neutralises one APB molecule, giving a mass of 211.

234/211 = 1.11 - which makes it 11% stronger weight for weight assuming no other factors come into play.
(211/243 = 0.90 is the factor if you want to convert your normal (succinate) dose to one for HCl.

Had a great time on 5-APB, though it was supposed to be MDMA. GS/MS test later revealed it to be be 5-APB. So when we dropped we assumed it was e. Anyway, I didn't get all that much lovey feeling as some describe, but overall felt quite happy and music especially sounded great. Had plenty of energy too. No trippiness for me, but my friend had some. Experience lasted awhile, but comedown was pretty easy physically and mentally, thought it was gradual and took some time.

Yes, but in combo with 6-APB, dropping the 6 about an hour in, so first coupla hours was nearly all down to the 5 and insufflates easily, fast come up compared to 6-APB. It was good stuff. See my previous post on the 6-APB thread (http://www.bluelight.ru/vb/threads/632565-The-Big-amp-Dandy-6-APB-Thread-%28Part-5%29?p=11016104&highlight=thoughts+combo#post11016104) for comments on that combo.

I read your post. So was it stronger than the succinate?

Sepher
01-11-2012, 10:56
Can't compare, only had the HCl, vendors I use always out of stock of the succinate when I tried for it. General consensus from other users on another site I'm on is that yes, HCl seems to have more oomph than succinate as per Transform's post and hits faster / harder. Take that with the pinch of salt it deserves. It's definitely stronger weight for weight, or is more straightforwardly stimmy at least than 6-APB succinate I think, got more from combo of 5 & 6 @ 100mg each than I'd expect from 200mg ( or maybe even 250mg ) of 6 alone anyways, by a good bit I think. More testing needed.

(211/243 = 0.90 is the factor if you want to convert your normal (succinate) dose to one for HCl.
according to some analysis, 5-APB succinate usually contains an excess of unreacted succinic acid. that's why the vendor's claim that 5-APB HCl is significantly more potent than the 5-APB succinate on the market is not that far-fetched. I would definitley recommend to start with a much lower dosage of 5-APB HCl when first trying this form of this compound. probably already 70-80 mg 5-APB HCl is equivalent to a standard dose of 100 mg of the usual 5-APB succinate.

I have tried 6-APB at ~120 mg and didnt like it that much, ok headspace and music sounded nice, but no euphoria and felt some nausea. Next time I will try a higher dose to see if that would give it the extra push i felt it needed.
Im going to a rave in about a month and im planning on trying out 5-APB there. Ive read a lot of positive comments about the 5/6-combo, but i want to try both compounds on their own first.
The only doubt i have about taking 5-APB on its own at a rave is that it is too mellow. What do you think? Is 5-APB too mellow for a rave, has anyone combined it with a small amount of amphetamine to give it some extra energy?

Jesusgreen
05-11-2012, 22:50
If you felt some nausea at that dose I'd assume it would get worse with a higher dose honestly. It's worth noting that going by the effects people experience - and going by the EC50 values for 5-APDB and 6-APDB - we can assume that 5-APB is mostly only serotonergic with very little dopaminergic action - even compared to MDMA which is vastly less dopaminergic than 6-APDB & 6-APB in itself.

Given that mostly/purely serotonergic compounds tend to be more anti-depressant than euphoric in action if you're looking for the 6-APB experience from 5-APB you'd have to push the dose up dramatically and at that point the excess in serotonin would likely produce nasty side effects.

Don't look for the 6-APB experience from this one, it's quite the different drug, despite sharing many similarities. Imo it's much more suitable for spending time with closed friends and loved ones as being more serotonergic at a similar dose results in more empathy and touch enhancement, but less of the mashed rushing and pushy euphoria of 6-APB.

For me personally though 5-APB's main purpose is to be used in combination with 6-APB. It's such a wonderful combination that far excels past either drug alone at any dose, the synergy is unreal. :)

I've heard good things about 5-APB and a low dose of amphetamine, saying it's much closer to 6-APB, so it might be worth a try - just don't push the doses too high as in my experience the APB's raise heart rate quite significantly when compared to other stimulants sometimes, and you don't want to put too much strain on your heart.

Nub

Thanks for the reply! Thats pretty much what i expected from what ive read about 5-APB. Im not looking for the same experience as 6-APB, what I would really want to do is just combine 5 and 6, but i feel like i have to try 5 on its own before combining it with 6. I try not to use strong serotonergic/dopaminergic drugs often, so i usually just use them at raves/parties. If i wait for a good moment to use 5-APB when just chilling with friends i will have to wait a long time and im too impatient for that :)

If i end up trying the 5-APB/amphetamine combo ill be sure to post here how it went! :)

A bit of-topic but the nausea i felt from 6 was during the come-up and peak, around the first 3 hours if i remember correctly, then it subsided. I think i will anyway try a higher dose(~150 mg) since that seems to be the sweet-spot for many and see if it gives me euphoria without much increase in side-effects. I was really quite suprised over the euphoria being almost nonexistent on 115 mg of 6-APB.

Jesusgreen
06-11-2012, 02:58
Seems I misread your post a little and read the 6-APB as 5-APB at the top. If you didn't find any euphoria at 120mg of 6-APB I'd question the quality, since I tend to need more than all my friends (they need 120-125mg, I prefer 150mg) but even I find 120mg a very euphoric experience, just not quite as intense as I personally prefer. I've previously had some lower quality off-white/VERY light tan 6-APB which gave me more side effects at a lower level and not as much of the euphoria, so that's a possibility. That said though, it's normal for a lot of people to get nausea on the come up, and the lack of positive effects at this level could be due to previous tolerance from MDMA and similar drugs.

If you want to get a good use out of 5-APB, I very much recommend either doing it at a quiet social event where you can spend more time sitting down and chatting with friends than dancing, or even just at home and spend lots of time rolling around under a blanket, playing some cool music, and in the shower - making the most of those epic tactile sensations! :D

As a general rule of thumb, effects which are shared between two drugs will cause tolerance to each other. Given the similar mechanisms of the two drugs I would expect some cross tolerance.

I've seen a few mentions of low-dose 5-apb being a social lubricant. To those that have found this effect, what dosage is useful for this purpose? I'm slowly working my way up from low doses and want to know where I'll begin to feel these sorts of effects.

Are you sure MDMA is LESS dopaminergic than 6-APB? I feel 6-APB is a lot less pushier and energetic than MDMA, which makes me want to bounce off the walls. Have any source for the EC50's of 6-APB?

Sepher
24-11-2012, 17:33
I agree Infinity. The APBs, 5 and 6 have considerably less push than I remember MDMA having, though we're talking pills around 1990/91 which probably had other stims in the mix but even so, Good E has a lot more bounce and energy than the APBs. Only been out on them once, 6-APB and MPA mix to cut through the heavy, lazy, just wanna chill thing I get from APBs but even so nothing like the danceability, quite difficult to sustain for long. Nowhere near the energy needed to rock your bollox off for 6 hours straight! ;) Definitely not as euphoric as E either in those circumstances, though every bit is sociable and relaxed, chatty with strangers and liking them and stuff.
