Um, one of them was one of the most experienced and knowledgeable people on bluelight, the other was friends with B9, another one of the most experienced people here. They definitely measured it right. I assume they just got in a manic state and kept dosing, something very likely to happen to others, especially those who try to use it or 3-MeO-PCE like ketamine (not to mention Jamshyd's comment about 3-MeO-PCE likely being MORE manic judging from the few reports on it).
50 mg IM 3-MeO-PCP is what made the one guy go catatonic, and that was with a hefty dissociative tolerance. I always had a great time with 3-MeO-PCP, but I never used more than 11 mg IM either. Of course I wouldn't hesitate to try 3-MeO-PCE myself -- I'm just saying making either available to a UK drug pig public accustomed to hoovering mephedrone is likely to result in a lot of bad press, arrests, and hospitalizations. Thankfully this first batch is going to be very limited, so the danger is minimal. I'd like to know more about the details of each OD, but at the moment I'd say worries about the fallout from this when it becomes more readily available are justified.
