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.
