Yes, I was very interested in this combo and did a first trial some weeks ago. I had previously tested 5-mapb alone about one month before, and 70 mg. were surprisingly strong for me. It provided great euphoria but a bit too sedating and lacking the magic of X.
Also tried 2-fma by itself and it seemed a mild but long-lasting stimulant at 20 mg. dose level.
For the combo, I wanted to start low (in the name of caution) so my dosing was:
-45 mg. 5-mapb
-22 mg. 2-fma
-5 mg. 4-ho-mipt
The experience was great, very similar to X but double duration. The next time I will increase 5-mapb to 50/55 mg., as it was a little bit below perfection
I think this combo has a lot of potential, with the advantage of being able to modulate the effects: if you want more empathy, you can just increase the 5-mapb dose, and the same way for the other two ingredients and their effects.
I wonder if this combo would be equally good using 5-apb or 6-apdb instead of 5-mapb, since I could get these substances too. Anyone has tried?
P.D.: I must say that I had not tried MDMA or any other serotogenic substance in the last 10 years. Then, last year I got back to these kind of substances and since then I have tried X twice (one time 100 mg. alone, and the other time 100 mg. + 20 mg. 2C-D), as well as the referred previous 5-mapb experiment.
