    Summary TripSit

    A rare psychedelic amphetamine of the same class as DOM. This is a powerful and potent psychedelic with all the effects you would expect from an amphetamine. Described by Shulgin as a 'heavy duty psychedelic'.

    Perspectives

    “DOPr is a marathon of a drug. The duration is of course the most easily remarked upon aspect of the experience. It is long, phenomenally long.”

    “The onset is slower than any other thing I can think of. There was nothing at all at the end of an hour, and only a threshold a half hour later. By the middle of the third hour, I was up to 1+, and that seemed to be about as high as it intended to take me. Attempts to sleep at the ninth hour were not successful, as there were strange patterns of not-quite logical thinking going on. Stuff like: β€˜The block events (like a baby’s rectangular building blocks) that were gotten, along with other things, from the full octaves of the left hand in Listz’s Hungarian Rhapsody, events that allowed an easy recognition of the odds of achieving successful re-entry from any of several erotic codes.’ Clearly this was not a baseline state. After six hours of successful sleep, I was still off-baseline, and on into the following day. Go on up with curiosity but with caution.”

    Over the last year IΒ’ve really grown to love psychedelics deeply, both taking & collecting them. These last few months IΒ’ve managed to get my hands on quite a few rarities and legendary psychedelics. After not that much contemplating I landed on DOPr being the one to mark the start of my (psychedelic) summer.

    I've had quite a bit of experiences, not so much with the different kinds of substances but more of the frequency of them. Mdma and lsd were used hundreds of times, and just a few trips from aMT, 2C-I, 2C-P, 5-MAPB and shrooms. I've used miprocin, metocin, adderall/ritalin tens of times.
