i tend to the following. dck and o-pce are a bit bland compared to say ketamine, but solid dissos especially in combination. tce (desoxy tiletamime) was way better, more in the ballpark of ketamine which is my favorite ach. 3meo-pcp i found a bit dark but liked it, it has its character id say. 3Cl-PCP was dull and without any use. and the o-pce oxime (which i got from a nl vendor, one of the bigger ones, still in business) was just ok. as i said, felt like glue in your brain.
and there was a really weird ach sold out of poland years ago to me as mxe. got it 2 times. short duration, really sick headspace and not that potent but it seemed to be an ach. i tend to 3-isopropyl instead of 3methoxy. took it nasally multiple times and when it started it felt kinda like it makes woooov in your brain. it was somewhat silly but something special. shop is closed by now, the owner is dead for all i know, he was german.
