Interesting, I haven't heard anything but if it came out I would be very curious to hear about how it is. I've tried base MPT and 4-HO-MPT, and I love both. I find them gentle and intellectual, somewhat LSD-like in their own way, in terms of the nature of the mental and even visual effects.
That actually gets me interested-I love analytical trips.
My guess (with only a rudimentary understanding of the science behind these 5 meo compounds) is that it would be active at a much lower dosage than those ones you tried -much like 5-meo-amt and 5 meo mipt.
Sounds great, been hoping for this one for a while. My feeling about MPT and 4-HO-MPT is pretty much the same as Xorkoth's.... It's a special group for sure. Can't wait to start hearing some stuff about this one.
