Yep - it's like coming up on vaped DMT, when you've only halfway depressed the plunger.
I used to take high doses of 4-aco-dmt IV, and the trips were fucking insane - but fuck, i wouldn't recommend it.
I did it at a time when i was taking drugs very recklessly - i wouldn't do it nowadays. Full-blown entity contact...i once floated through the ceiling and entered this world that i could move around in and talk telepathically to little elf-like creatures that showed me writing in some strange language.
I've not really discussed those trips on bluelight much before, because i really don't want to inspire other people to try it.
But fuck it's incredible - like smoking a massive dose of DMT and continuing to trip for hours.
I used to take about 45-50 mg to break through, and i once took 100 mg which i imcorrectly assumed had degraded. that was fucking unbelievable, and not necessarily pleasant.
I used to really enjoy it with a good dose of MXE in the shot. Those were the days... I'm just glad i made it out of that period without dying or suffering serious harm.
Be careful man, i think if anyone's going to do this, you should have someone help you administer the injection. It comes on way too fast and way too hard, and you really wouldn't want to break through with a fucking spike in your vein.
It is amazingly like vaped DMT though, i absolutely agree.
I would get that buzzing sound as it kicked in, and crazy visuals. Wild, but not exacly a chilled trip.
