I use volumetric dosing.
It's not active as in a "Shulgin+".
But something happens.
I experience more flexibility and muscle control during yoga. And I finish my swimming routine (3km,like 2miles) 10minutes faster. That's not placebo..
But thanks for clearing up that it won't interfere with a trip.
For the record. I use 30mg aMT when going out, works 12-16hours. Friends experience the same. I used 40mg and it was overwhelming (this was at a techno event).
