Sounds about right to me. It's a lot more potent though and may be less forgiving to those overdoing it.
It's obviously more intense and serotonergic than methylone.
I dont really compare it exactly to MDMA. I picked up a gram of this from a reliable source, with NMR analysis and all. I did roughly 200mg snorted one night, and then a week later did maybe >300mg snorted over the course of about 14 hours.
I found a lot of key differences between this and MDMA:
- Very very easy to redose and boost the effects. MDMA re-dosing for me is really subtle, and only seems to prolong the effects as opposed to boost them to any extreme. with 5-mapb. Snorting this in 40mg lines was able to continuially boost and continue my high with no problem. I found really no tolerance-esque effects.
- This is a lot more serotonergic than MDMA. After getting up to about 70 this stuff became pretty psychedelic. But a really pleasent psychedelic. MDMA has that small amount of psychedelia associated with it, adding to the roll. But this was a lot different. Instead of a strong roll, I got a feeling similar to a low dose of mushrooms, or 2c-i. I was getting CEVs, and some distorting and morphing with my OEVs, like I said, very close to a medium sized dose of mushrooms, however with a LOT less anxiety. Mushrooms, 5meo-mipt and such always give me a decent amount of anxiety. I didnt get as much with 5-mapb, however it was still there. Which leads me to the next point:
- In a club environment the "roll" might be present, but its not a strong eyes in the back of the head roll. Its much more psychedelic, not nearly as much dopamine release in my opinion.
- It hits a lot faster than MDMA when snorted. I was feeling strong effecs within 3 minutes of snorthing. Im talking PEAKING dopamine-wise within 3-4 minutes, serotonin-wise in about 10.
Very stimmy at lose doses around 50-60mg, after that becomes pretty darn psychedelic. MUCH MUCH more so than MDMA or even MDA for me.
I mean overall, it was a fun chemical. I ended up just ripping like 10 of my vinyl records to digital format, and listening to old blues all day. It was fun. There was a bit of anxiety associated, psychedelic related anxiety that is. A small amount of "roll." To be honest, it was a bit more psychedelic than MDA to me, and I much prefer MDA because of the strong roll that comes with it. This is a fun chem, and at a dose of maybe 80-100 in a club environment it could be super fun. I just found it too similar to stuff like 5-meo-mipt, lacking that solid dopamine rush that comes with MDMA or MDA. Maybe one day Ill finish my gram, but for its just gonna sit in my drawer.
Note: at a lose dose, like 50-60mg snorted, this is a LOT like a medium dose of MDA (perhaps MDMA or a mix).; definitely pretty stimmy at low doses. But once you surpass that 50-60 snorted, it becomes a baby version of mushrooms. And of course, youre gonna want to up the dose

.
That said, something like 50mg of this (snorted of course, I never tried oral) mixed with decent amount of a normal stimulant, might provide for a VERY fun time. But again thats just speculation. If there are any questions Id be happy to answer them, I just wanted to get the main bullet points out there. This stuff was not nerely as euphoric as MDMA or MDA to me, just my two cents. It was like baby-MDMA, and medium-psych. I can see some psych-heads getting WAY into this, especially because tolerance doesnt seem to be much of an issue.
