So after getting myself a gram of 5-MAPB on a whim, and doing an allergy test last week, I decided to snort up ~100mg tonight. Purchased from what I consider a very reputable vendor (please no fucking PMs regarding that) This is a fun chem. Its very very similar to MDA in its effects profile. MDA has a slight bit more body high, and a teensy bit more psychedelia, namely closed eye visuals for me.
I was thoroughly stimulated, both amp-wise, and psyche-wise. The psychdelic aspect felt extremely similar to MDA, or perhaps a light dose of a gram of mushrooms.
I could easily see this becoming an MDA replacement. Id wager that 70mg 5-MAPB + 30mg of some generic stimulant (or even 4-FA) would make for an incredible time.
Sex drive was increased, however not as much as substituted cathinones increase it for me, also it was EXTREMELY difficult to maintain a hard penis. Like literally almost impossible to stay hard for more than a minute or two.... which sucked. However it didnt have any negative effects on my bladder and urinary system which cathinones do to me in large amounts.
Like I said, this was very damn similar to MDA, with a bit less body high, and a tad bit less "true" psychedelia. Still a winning chemical though, and I will definitely be putting the rest of my gram to use in the coming months. The total "main course" lasted about 3 hours (tops. ) The come up was only 20 minutes, but keep in mind I insufflated it. I know some people in this thread have discussed having powder so fine that it was unsnortable. I have come across "6-APB" powder in the past that functioned exactly the same. I ended up flushing it. The 5-MAPB I received was a fine powder, already crushed, but wasnt too fine that it still went up the nose fine. The after effects were a solid 2-3 hours, however I took a mirtazapine to help sleep.
Redosing really dose wonders. I know that when I redose with MDMA, its hard for me to get any noticeable boost, merely a prolonging of current effects. But redosing 5-MAPB, even small 20mg amounts, can really throw it back into the trip pretty easily.
All that said.... this chemical is EXTREMELY close in structure to MDMA, and MDA and the effects are very similar. Treat this as such. Just because its cheap and not "technically" illegal per se, it can still drain your monoamines, and screw with your day to day function. I would restrict use of this to once a month.
Id be happy to answer any questions regarding this chem. Obviously I cant say with certainty it was what my source claimed, however I have good reason to believe it was, and the effects were a bit different from any similar-in-structure RC I have tried in the past.
Cheers.
