i always found 2CB orally a bit of a hit or miss, with 27mg i had a really nice +++ but on 32mg of the compound i was feeling a ++ at best (set and setting spring to mind), nasally i always found 10-15mg to bring me to that exact +++ headspace , it hits fast and is gone by the 4th/5th hour but unlike some 2C-x compounds nasally i didnt find it as stimulating (quite relaxed) , and as for 2C-T-7 nasally (dont even go there)
Alot of people say they are not to be snorted phenylethylamines things like MDxx 2C-x they definitely are not but i really do like 2CB nasally (though it stings like a bitch) be ready for ur eye to water like hell , but within two minutes u forget the pain the headspace and visuals are that delicious
definitely not reccommended with any other of the 2C-x's
