Once again I feel obliged to intervene because the euphoric wave we all tend to ride on after tasting the bliss of this lysergic paradise is highly dangerous to all the unexperienced people reading along.
This substance has not only once proven to be as potent as LSD when it comes to fearful ego-loss, mind-shattering effects, retraumatisation, profound anxiety, spiritual experiences and so on.
150 microgram is a serious dose for unexperienced users and bad-trips are entirely possible.
Most of us wouldn't be able to distinguish this substance from LSD in a blind test, as set and setting play a significant role in the effects of every psychedelic. I conclude that the above mentioned experiences are insufficient to describe the full picture of the possible effects of this substance.
I assume that most of the experienced users reporting here have mild to moderate tolerance to psychedlic substances. Since considerably weaker effects even four weeks after dosing are a commonly experienced phenomenon, most of the reports might consequently be biased .
