2c-i creates a moderate tolerance for me, I would wait about 5 days in between doses in order to get the most full experience. However, it's not as dramatic of a tolerance as I experience with tryptamines.
The other issue is that my two 20mg doses are in separate bottles, dissolved into alcohol which is diluted in drinking water. To approximate a 30mg dose, I could pour half of one bottle into the other and hope the material is roughly evenly distributed through the solution and not concentrated on the top or bottom. I would then be left with a 10-ish mg dose to find a use for. It would, of course, be trivial to drink all of both bottles for the 40mg dose.
