Yeah I have some & tried it 2-3 different times, also friends have tried some around here.
It does seem like pihkal is way off on this one, well with the dose especially. The DOC I have has been analysed and its ~100%. I read someone's post on another forum saying that Shulgin screwed up the synth on this one, saying "some of it" (i'm assuming they made some according to his synth) was analysed in Germany and found to be a multi chlorinated PEA, I don't know the source of this info but I read before this on synthetikal - a guy posted on how he tried to make some DOC, but ended up with 3,4,6-trichloro-2,5-DMA, yet it was still active at 5mg and was well liked "2c-b like visuals" anyway..
Lowest dose taken was about 4mg, one girl who took that dose got "lost in a spaceship" (which was fun apparently), i've taken up to (i think) 8mg. I certainly tripped my balls off at that dose, but it was moreso CEV's when I laid down and closed my eyes and kinda got "lost" in it myself. I remember my consciousness flying around these fractal highly detailed buildings and became so vivid I guess it made me "wake up". When I opened my eyes I was tripping although the OEV's weren't anywhere near as deep.
It definitely lacks a body load, reminded me of 2C-C in that well, I did kind of "fall asleep" but not really, sorta dosed off into lala tripping land.
Both DOI and DOC seem so incredibly easy on the body compared to ...shitty DOB

. DOC seems less potent (and definitely the shortest acting of all of them) but then i'm not sure if I could see myself "falling asleep" on DOI or DOB (well, actually, first time I took DOB I was tired and did fall asleep).
With me I get quite 'giggly' on DOC and laughter comes easily. Out of those three DOx's i've tried i'd so far say DOI is my favorite, but actually it seems like lower doses of DOI + some DOC might boost the visual aspect up a nice bit.
[Moderators note: there is reason to believe the DOC in this report may have been contaminated with 2c-i. Beware that the dosages here are not considered appropriate for DOC]
