I sampled ~10 mg (11 ± 2 mg to be picky) of this yesterday, on an empty stomach. It has a notably long but smooth come-up, I'd say about 45 minutes to first alerts and doesn't really hit its stride for a couple of hours, but there's very little in the way of body load, jitters or anxiety. A very pleasant and friendly vibe to it, music was definitely enhanced and I could certainly see that it would be good for dancing, while not being particularly energetic. Visuals were somewhat missing at first, mainly just a bit of brightening and colour aberration, but after about four hours or so, I was seeing more patterns and mandalas with eyes closed (my visual cortex is on the easier end with respect to triggering). It was still going at the 6+ hours point, although beginning to slowly descend, when I ate ~30 mg MXiPr, but at a guess I reckon it was likely to tail off around the 8 hour mark.
I'd say out of 2C-B, 2C-C, 2C-D or 2C-E, it's closest to 2C-B, but a little more refined.
Two thumbs up - would do again.
