You should buy a test kit, then... It really doesnt sound legit.
Yeah well after further research on another site it was tested and it's not 5-MAPB, so I'm no further along in knowing how to handle it, I like it but it's wrong that the vendor can't just be honest and tell me what I've got. The wonderful world of RC's I guess.
 
(tested + top vendor)
Me and 2 friends took 60mg of 5-MAPB each. Two of us got the expected effects, the third one felt nothing. Pupils were normal. He's not on any medication and it was his first time taking a drug of this class. Anyone have any ideas what was behind it?
I know 60mg isn't a huge dose but I'm twice his size and have a bit of tolerance and felt it fine.
 
I feel like I should be chiming in a lot more in this thread, since I've consumed a fair bit of 5-MAPB since it first hit the market.

I'm still convinced that the very very first batch that was introduced must have been something else, maybe even MDMA, or cut with something very stimulating and with a similar duration and potency, because that was the only batch that had us moving and dancing and eye-rolling and gurning. It also had a powerful empathogenic effect that just isn't possible with the "real" 5-MAPB that is circulating now.

I'm still hoping someone else on BL tried that first batch. I believe most of the people who bought that first batch are on a different, UK-based forum that doesn't allow any discussion of banned chems. Apparently the outrageous price at the time (about the same as MDMA, actually) kept US customers from trying it... Supposedly it tested just like MDMA, but since no one has any laying around most likely, I guess it will remain a mystery...

**********

ANYWAY, all that aside, I do have an actual question for you guys ;)

Is there any reason NOT to use 4-AcO-DiPT in place of 5-MeO-MiPT or 4-HO-MET in the combo mentioned earlier? I figure it's safe, but it doesn't hurt to ask. Assuming it is safe (enough), I thought 5mg would be sufficient? Thoughts?
 
I can't really comment on the 4-AcO-DiPT substitution, but I'm also a little suspicious of the early batch(es), specifically because it seems that the reports of severe after effects seem to have tapered off since the material became more widely available. I don't want to put words in anyone's mouth, but I think one of the early reporters speculated as such in a somewhat recent post.

Still, I'm a bit more cautious with the MAPBs than I probably would be otherwise and advise others to do the same.

This old chestnut? "I used [serotonergic drug] quite a bit but now it's different, I think that the drug has changed rather than the neurotoxicity/tolerance causing the change".

How often have you used wintermute?

@Hellp there is no way I would regularly use anything with even the slightest suspicion that is was 5-MAPB. We have had passionate warnings from several users about overuse of this compound.

@Black53 impossible to say. Sometimes the planets just align the wrong way. Try again with a little more but don't go doubling it or anything silly like that.

Did you ever find out what it was? How close were the effects you got to the effects profile of 5 mapb? Your posts had me curious.

I've also tried a recent batch (3 months ago) of this stuff. Pretty much what I expected from what I read. Euphoria, nystagmus (more so than mdma), elevated heart rate, lots of empathy/great mood, jaw clenching, music is real nice, no appetite, difficulty sleeping, etc. Though I had the fumarate version, you should still get these effects if it was really 5 mapb. I've done mdma thousands of times, so I can instantly recognize 5 mapb's similarity to it. When you took it, was it mdma-like and how so?

5 mapb's negative effects are worse than mdma imo. Abuse this one and inevitably you'll get some bad condition, whether it's Serotonin Syndrome or what have you. I'd be surprised if what you took really WAS 5 mapb, because 5 days straight and feeling well means you're lucky. Though this stuff almost teases you into taking more because the duration is shorter than mdma, not as magic-like and it takes longer to hit you, don't fall for it. This one is more unforgiving than mdma, by far.

I'd say find out what it really is before taking any more. Until then, you won't know what the dosage is, how often to take it, what you shouldn't combine it with, etc. You have the hcl version too, so take caution.
 
Do 5-mapb cause strong vasoconstriction? Like Speed(speed dick) . Many seem to like it...my favourite is still methylone because it feels for me the closest to MDMA. 5-MAPB I felt literally nothing, but probably because of SSRI&Mirtazapin. Only with Mirtazapin I defnately feel the effects of methylone.

So, worth trying? I dont like psychedelic empathogens, I mean sure, I like them, but I am looking for something not to overwhelming, least side effects. Because even MDMA is cheaper than this...and MDMA is one of my favourites with the least side effects, at least on my body compared to methylone once overdosed...
 
SSRIs will block the serotonergic effects of SRAs. Since 5-MAPB is quite selectively serotonergic it is not surprising that you got no effects.

Yes, it does have strong vasoconstriction. I'd say at the latter part of the roll, when most of the effects have tapered off. That's when you'll feel it most. But it's possible that you may not get this side effect.

5 mapb is strong on its own, but it doesn't quite reach mdma level high. Though this one is very similar, it's definitely missing that mdma peak. It takes you a step below but you feel it strong there the whole time until it wears off.

Maybe that's why some people like it; compared to mdma, when it's at that "80%" level, 5 mapb goes at it hard. Mdma will coast past that zone like an afterthought.
 
so-so

I tried a dose of 60mg 5-MAPB and 10mg FMA-2 on an empty stomach bombed. It did not go anywhere except a mild state of mind. I was yawning 3 1/2 hrs afterward. Weed did not bring it out. This was the light tan powder. I was not impressed. No noticeable comeup, peak, comedown. After reading the stories in this thread I did not want to redose or add anything else to the mix. Have enough 5-MAPB left from my sample for one more good dose. Thinking of mixing with 4-FA or a-PHP. Anyone familiar with these combos? Anyone tried plugging 5-MAPB?
I got a batch of 5mapb, and I feel the effects at low doses: it's pretty obvious to me even at 30-50mg and I've added that to DOC or 4-aco-met now with good results. However, my friends who I've given it to have felt nothing at these lower doses, and felt only mild and brief effects from more "normal" dosages in the 100mg range. My guess is that the stuff I have just isn't all that strong--but I'm particularly sensitive to it. It's a nice chemical though. Good entactogenic rush, very pro-social. At least in the context that I've used it (adding it to other experiences) I can only describe it with glowing results.

We'll turns out it was A-PHP, which as you can imagine could have turned out very bad if I'd done a big 5 mapb dose, if nothing else a good reminder to use a test kit if possible, and at the the very least always start with a low test dose.

Hmm, it may be a good idea to seek a more reputable/trustworthy source. But a test kit fixes that too. Good thing nothing bad happened.


Looking back at this thread, I think I was a little too harsh on 5-mapb. It's really a nice one, and I've had good times from 150-200mg sessions (mostly to chill with a friend and/or listen to trance). Obviously, I have a very high stim tolerance and even at that range, I can tell there is more to this chem. Felt like a medium range dose to me. It definitely has that euphoric push and the empathy has a "sedative" feel to it. You won't be spilling out your deep life experiences, but you'll still carry a conversation more smoothly than normal.

I went to the dark side after a couple sessions 2 months back, took 100 mg caps 4 times in one night because I wasn't satisfied, and still my mind and body wanted more. That's when I felt vasoconstriction on my lower legs/feet, which I never got before on anything, and just had this gut feeling this chem really wants to bite your ass. Maybe it was because of a user here (forgot his handle) who made a ton of warning posts, and maybe it did make me a bit paranoid, but I definitely felt the vasoconstriction that night. I didn't get anything else, not even afterwards, but still. It made a statement of its toxicity when abused.

Unlike its close cousin mdma, redosing on 5 mapb will bring it back on as if tolerance is in the background, even during the comedown. That was my last time redosing, and my best times were simply dosing once at an appreciable level. Note that I did not get vasoconstriction when dosing ONCE, only when I redosed that one night.

My best suggestion would be to find your sweet spot and then stick to it. Redosing will be a blessing in disguise. I suppose comparing it to a similar chem is a decent guide, eg. if 100mg of e hits you good, then 100mg of 5 mapb would too. When it's taken right, it's very worthwhile (in fact I still have a lot left and eventually I'll consume it all).

That's about all I'm able to contribute here. Peace.
 
Hey guys. Just wanted to share my overall experience with this substance.

Before I get into it, I never tried mdma, but am fairly experienced with drugs, being a regular pot head for almost 8 years, occasional salvia and mushroom experiments, and tryptamine RCs. The only phenylethylamines I ever took were 2C-D and Ethcathinone.

Anyways, so decided to give this one a shot, as from what I'd heard it seem to mimic the effects of mdma pretty close. I ordered some, which came in 110mg pellets. Now, when it comes to psychedelics, I'm a very responsible user, taking every harm reduction measure there is in measure. But, for whatever reason, I acted much dumber with this one and started searching into HR well after suffering from mild to seriously annoying adverse effects. So here it goes :

(oh btw, I didn't really keep much track of time except for a few instances)

First try, take the 110 mg pill. Wait for the effects to kick in listening to music and surfing the net. Some body rush starts to kick in around 45 min later, and 10 min after that I realize my head is just moving on its own with the groove and I can't stop it for more than 20 seconds, so I say that must be it. As I move around my house, I start to feel better and better, all my anxiety just vanishes (I'm a pretty anxious dude) and I'm amazed at how impossible it is to just feel bad -literally, when I think about something that might trigger a mild anxiety crisis on weed, I'm just UNABLE to feel the least worry about it. I chill for a few moments, just feeling good and enjoying the music. I understand why this kind of compound might be useful in therapy.
Then I decide to take a shower, and while I walk to the bathroom I notice my body starts to dance uncontrollably to some corporate edm (it was rihanna I believe) and it feels GOOD -note that I would never listen to shit like that, I believe it was playing over a video. While in the shower, it just keeps getting better and better, and as soon as I get out I decide to drop the other pill. Approx half of it got crushed in the mail, so I eat half and snort the rest, which gives me an immediate and pleasurable buzz.
As the second pill takes effect, it almost gets psychedelic -light seems to get that particular deeper look you get at the beginning of a tryptamine trip, and (I know this sounds weird) I get the sensation that there is a blue-ish electric buzz/fog surrounding my vision. By that time, I have severe jaw clenching and eye rolling.
Anyway, after a few hours, the euphoria diminishes considerably, but I still feel very stimmy, so I wait to get sleepy, which lasts quite long. I dropped the first pill at 19 pm and the second around 21 pm, I believe I slept around noon the next day.

When I woke up I felt kind of empty, depressed but somehow I still enjoyed edm highly. I think my depression feelings were more related to the fact that at that point in my life I had nothing to do, and last night's experience was so awesome that I dreaded the monotonous days to follow. The same night I took 30 mg of 4-ACO-DMT which is another history altogether :) But I know it was very irresponsible of me to do that, and I'm a bit angry at myself for doing so, cause as I said that's not how I use psychedelics. But the sense of emptiness at that point made it look like a good idea.


Anyway, my second time with 5-mapb was the weekend that followed.
I started with a combo of 5-apb/4-fma of unknown dosage (my friend who gave it to me said it was a medium dose -I know, very irresponsible, again). Didn't quite like that particular combo, as it felt too stimmy and pushy, and not euphoric enough. Now, I also had 4 pills of 5-mapb (440 mg that is), and I'd convinced myself not to take them, to keep them for a future time when my partner would be back from vacation. But the dissatisfaction with the apb-fma combo got the better of me and I took half a pill. From then on, over the course of, I'd say 5 hours, I regularly crushed half a pill and snorted it. The feeling never got as good as my first experience, and no wonder why!

I stood awoke for 30+ hours. The last 2 hours before I fell asleep were pretty weird : when I closed my eyes, my mind would wonder off of my body. Here's what I mean : let's assume I was playing guitar, and I closed my eyes. My body would continue to play the guitar, but immediately my mind would start to make up some conversations between, let's say, my father and the president. The weirder part is, the conversation I heard felt GENUINE, as in they said to each other what they would probably say to each other if they met in real life. BUT -and this is the weirdest part- their conversation would ALWAYS have some sort of subtext relating to playing guitar. Pretty surreal experience.

Fell asleep, woke up the next day, feeling really tired. Sometime during the night, as I was picking my nose, I noticed a good amount of what I had snorted was still sitting in my nose! So I did something normal people would consider gross and ate my 5-mapb ridden boogers :D It didn't quite set me off but gave a nice buzz to the evening.

My third time was dosing 50 mg on a friday, then 75 mg the next day. Spent time with my partner the second day, was a really bonding experience, but I didn't get as high as she did, since I dosed the previous day.


It's been a month since my last dose.

OK, now, here are the bad side effects I felt with this product :
-brain zaps : started during the week that followed my first trip, but I thought it was due to the huge amounts of space cake I was eating. Got much worse after my second time the following week. Strangely enough, didn't have them after the third time, although I dosed 2 days in a row.
-depression : I'm already a depressive guy self medicating with marijuana, but I must admit I felt pretty f**king low for a few days, especially after my second experience. Also, the week that followed my first time, I cried a LOT, and I usually never cry. Didn't cry over sad things either, just felt emotionally overwhelmed buy even beautiful things. Gotta say, although it felt weird to have such mood flings, it also felt good to feel those emotions.

However, the thing that worries me the worst are the weird feelings in my chest. I feel like ever since my third experience I have heart palpitations, as if all of a sudden my chest became an endless well and my heart fell through it in a fraction of a second, or as if someone caught both extremities of my heart and pulled it real fast.
At first it scared me shitless, it happened several times during the day and each time I felt a panic attack waiting at the door.
However, I suspect it might be just that my reflux got worse. I read that reflux might cause angina-like symptoms, so I got myself some Gaviscon and it seems to have calmed a bit.

So yeah, that was my story. All in all, I think it's a very nice compound, but I acted stupid and took it without prior research. Next time I'll be much more prepared, taking into account every safety measure I can. Cheers.
 
Couple of things, one, SSRIs don't block 5-MAPB, they do however increase the threshold dose. I don't recommend taking them. In fact I fought hard to get someone not to do so. Two, Rainey and Si Ingwe must be predisposed to serotonin system problems either genetically or from extensive prior use of serotonergic drugs. I hadn't read their warnings and researched it four times in nine days, once back to back although it could be called an extended session. Because of the action of SSRIs serotonin syndrome is hardly a risk when taking the APBs. They simply fight over transport mechanisms. With a higher dose, breakthrough can be achieved as my SO's test proved. Anyway, I guess I'm here to say that either I got a particularly good batch and it doesn't have hardly any negative after effects, I'm told it is just under 96% pure (unlike theirs), or there is some kind of monkeyed up brain chemistry causing the negative experiences. Anyway, I'd love to hear other's thoughts on the subject. Thanks.
 
I have to wonder if those experiences were really with 5-MAPB or if it was something else. I have also tested 5-MAPB three or four times in a two week span, including consecutive days with doses in the 200-250mg range, while in the midst of a very reckless nine day binge including methylone, 5-APB, and 6-APB, and suffered very little in the way of acute negative side effects. I was also not especially responsible with these drugs in the months leading up to or following that binge. I don't know if it's reasonable to consider ROA, but all of my x-(M)APB doses have been oral.

In the week immediately following the binge, I experienced two short episodes of brain zaps while trying to sleep. In the months since, there has been some lasting lethargy and anhedonia, but even these symptoms have not been especially severe. In my experience with SRAs over the last year, 5-MAPB is actually the only one to even give me an afterglow as opposed to a crash.

However, I don't mean to discount those early reports. I would urge others to use extra caution with 5-MAPB, keep doses low and infrequent, and do not repeat the mistakes made by myself and others.

I looked back in the thread and it was that Si Ingwe poster with all the warnings. In spite of that, I was excited to try this one from all the glowing posts from others, and my familiarity with mdma and meth.

I'm pretty sure this stim, or any other, will be hard on the cns for many individuals if abused. Such as the poster, Sinan, who I'm assuming had chest pains from taking it the way he did. There are people out there who can take monster doses and have no ill side effects, but I think with 5 mapb that can be dangerous if it's used without caution for most people. Well, just like other stims.

I've abused mdma in an idiotic way for years, and never had any side effects except insomnia, weight loss, and dark circles under my eyes. With 5 mapb, I didn't get anything except vasoconstriction, but it was strong enough to concern me as that can possibly lead to very ill consequences. Who knows what else it can do to susceptible users, since there are only first hand reports and almost no scientific research?

As always, BL (and Erowid) have the most info on rare chems that isn't found anywhere else. I think info on what can or does go wrong is very useful, even if it may not apply to some of us.
 
I did it again this weekend at 110 mg doses, redosing just once at t+1:30.

I also took a fair amount of gaviscon throughout the experience, as I've read on BL that reducing acidity in your stomach can help better absorption of the drug. I think it worked, as I felt the peak last considerably longer. Also, as I said, I have reflux, so it soothed my stomach.

I also kept a healthy diet pre and post loading for the first time, which helped the experience. I didn't feel depressed (well, the day after I had a nice afterglow, but I also felt a little sad knowing the experience was over and I had to wait a while before doing it again). Also, I believe my chest pain might have been due to reflux indeed, as I feel much better now, even after having had the drug recently I haven't had any serious palpitations.

I'm thinking, with long breaks, strict pre-post regimens, reasonable doses and maximum one redose at no later than t+1:30~2:00, this drug can make wonders.

However I didn't feel like I could dance for a long time without losing my balance, though that may be related to the fact that I hadn't eaten a lot that day and I smoked like 1.5 g of weed through the experience.

And yeah, SERIOUS jaw clenching. I took maybe a whole gram of magnesium through the day and still, my jaw hurt like hell until the very next evening.

I must add though, I sense some addictive potential with this one. It really feels good, and whatever quantity you have, you wanna go through (at least I do).
 
ˆ weren't you suffering from a long term comedown a few posts back?
Take it easy bro... If I were you, I would wait at least 3 months for the next time, and that is if you are already feeling normal again.
 
Ya, this stuff makes you want to redose, but if one has a hard time with that then it's probably better to take a chem that is longer lasting.

Personally, I don't have time for really long trips but I absolutely love and miss them. Maybe all nighters but nothing past that (missing 2C-P...aMT lasted much longer than 12 hours for me). I have to drive a lot where I live.

Or you could potentiate the 5 mapb with minor enhancements eg. rolling tricks, weed, setting, music, etc. Combining stims with weed does wonders, esp. in a group setting. On your own is good too though. But this warrants a little caution (increase in hr/bp).

Try not to dose this stuff more often than you should, given how you reacted to it on earlier trials. 5 mapb is a short lasting, but strong chem. Um, enjoy it while it lasts? That's probably the best way to approach it.

Your choice though, I'm just giving you a suggestion.
 
Yeah, reading all of these reports, it sounds like not everybody is getting the same chemical here.....I also have heard that some people say theirs is brown and others say it's white. The only time I tried this stuff, it was a small sample (and it was white, fluffy powder, not brown at all....) and I started with literally a 1 mg allergy test, intranasily. I felt the buzz instantly. I felt a great change in headspace, to a much more peaceful, rolling one. And I loved this feeling. All from 1 mg! I was thinking to myself, I can't imagine what it would be like to take the whole 130 mgs at once. So once I figured the chem was legit, I took a bit more until I worked up to probably 30 mgs and I was rolling very hard. Much better than any other RC on the market right now. Better than even pure MDMA. I Was shocked that this chemical is so good, after reading the reports, I didn't get my hopes up that high. Some reports are good, but most of the reports don't do this chemical justice. Bottom line- IT IS BETTER THAN MDMA, IN EVERY CATAGORY. It lasts longer, it's stronger, it's has less of a comedown, no bad side effects, etc. Again, the stuff I tried was white, and not brown. I know I had the highest quality batch obviously, just by reading the reports....my experience was up there with pretty much the best. No way anyone could have a bad time on the stuff I took unless they were allergic to it.

Also I should note that I have heart problems and I get lots of breathing difficulity when I do stims...so much to the point to where I had to quit doing them. But 5MAPB did not do this to me, I felt good the whole time. I feel like this is the LEAST toxic RC on the market right now. And I kinda abused it too. The little bit I had, I did it all within 2 days. So I basically rolled two days in a row. I rolled just as hard the second day as I did the first. So, I had two full rolls, on only 130 mgs...and this includes redosing several times and rolling the whole night. I rolled for probably 30 hours total while awake. MDMA you can't do that, the effects get less and less with each redose usually. Not with this stuff, at least not in my limited experience. Amazing chemical all around. Seems almost too good to be true.

This is even better than the 5-IT which was going around several years ago, before it was banned.

Also, if anyone is wondering this stuff is NOT psychedelic...not in the trippy way, like LSD and mushrooms are. 6-APB is far more psychedelic than this stuff. And far more boring. I don't really like 6-apb too much on it's own. It has it's good points but 5-mapb is all around a far more enjoyable drug. Especially for partying.
