Just for the record, a 7mg dose of snorted 2-CT-2 is WAY more visual than an oral 2-CT-7 dose or an equivellant snorted dose.
One time I snorted 10mgs of it and it was one of the most insane experiences I have ever had. At one point during the trip I put on headphones and a Thee-O mix tape. Not only did I "see the music", but I actually was sucked into my headphones and floating in a universe of sound. Definantly in my top 5 most mind blowing trips.
HOWEVER it has considerable side effects including heavy nausea with a really good possibility of vomitting, pretty intense muscle tightening during the first hour or two, and a god awful hangover as well as a general poisoned feeling that lingers for a day or two afterwards.
7mgs is about as high as you can get without getting really severe symptoms. Although even between 5-7mgs, you're still going to get a lot of side effects.
I'm pretty sure 2-CT-2 and 2-CT-7 are very unhealthy for you from experience.
In retrospect I don't think either of them were worth trying, either.
