Do I have to wait 3 months to try 5-MAPB again if I underdosed?

A little over a week ago (July 18th) I tried 5-MAPB for the first time. I took 1mg/kg of body weight which equated to 70mg of 5-MAPB HCl after reading countless trip reports and my experience was unfortunately a massive let down. The effects I experienced were jaw clenching, increased body temperature, increased perspiration, dilated pupils, and a general sense of intoxication but there was no euphoria, nothing entactogenic at all. It felt similar to a DXM trip without any of the dissociative qualities. Like a robo-trip without the trip.

Anyway, the point of my post is to ask if it would be okay to try it again sooner than usual since my experience was so lackluster. I know it's typically recommended to treat it like MDMA, and I generally have no issue doing that, but in this situation I'm kind of itching to give it another try.

Yes, treat it exactly like you would MDMA or other SRAs. You could roll again, but just don't make it a habit (or do, but I presume you know what will happen). I don't believe anything terrible will come of it. I'm very sorry to hear that you didn't experience the true beauty of 5-MAPB. I'd say wait a month since you last took it, which is coming up, take it if you want, and then forget about it for a couple of months.

I believe you'll enjoy it more. It's exactly like MDMA, but not stimulating at all. It’s longer-lasting as well, and I find the comedown much smoother. With MDMA, I often reach the end and think, "Fuck, I should’ve redosed." With 5-MAPB, I feel much more content just letting it come to an end and returning to baseline.

Stay safe, and I really hope it works for you! The benzofurans are tricky to dose, considering how wide the range can be in terms of purity. I have some 6-APB succinate that tested as ~35% 6-APB and ~50% 4-APB, with the remainder being leftover succinic acid. Then again, I have 5-MAPB HCl, which I was told to take 85mg of, and 5-APB HCl, which I was specifically told not to go over 60mg with. Dosing reports are all over the place...

Good luck, brother!

Crazy to me that you didnt feel 70mg very strongly! I fluctuate between 175-185lb (around 80-85kg). It's been a while since I've tried 5-MAPB, but 70mg is typically enough to get me rolling decently. I'd usually dose around 60mg iirc for a good roll. Have you done lots of MDMA leading up to this? Did you take anything else? Any medications or supplements?0

Also what @crazyotter87 says; batches vary wildly. They are sometimes not even what they state. My most recent batch of 6-APB that I got is most likely actually 5-APB

No, I've only done Molly once, 7 years ago, and it wasn't properly tested so I'm not certain it was even MDMA. I take 5mg of Adderall once a week but I did not take it the same day as 5-MAPB and I take 400mg of Magnesium Glycinate every day. Around a week prior to consuming 5-MAPB I took 400mg of DXM HBr which is a pretty strong SNRI so I do wonder if consuming them in such close proximity could have negatively impacted my 5-MAPB experience.

I think I'm just gonna go ahead and wait a couple more months. It feels smarter to practice self-control and wait, even if the more hedonistic side of me doesn't want to wait. The dosing information has been pretty mixed, the source I got mine from suggests people take 100mg or more which seems rather high. Thank you for the info, it's much appreciated.

Id be extremely skeptical about getting the chemical they say there selling you these days and the quality of said chemicals. With all the bans and everything they have to change the way they cook em.

My guess (and a guess is all that it is) is that it's more likely due to the batch itself vs any sort of tolerance. 5mg Adderall once a week most likely wouldn't be enough to create a noticeable tolerance towards. 400mg DXM is a pretty strong dose but if it was around a week then I doubt that had much of an influence, tho there is some probability there imo, depending on an individuals metabolic process.

Do keep in mind that when I was playing with 5-MAPB fairly often was nearly 15 years ago. In general terms, the quality of RC's these days seems to be lower than in years past

agreed.
