Here is a picture of some 2c-e that I got a while ago. It was around 20 to 21 mg and was mixed with everclear. The visuals were way stronger than a regular LSD or mushroom trip. PS.. how many ml of liquid would you say is in the bottom of thhe cup.
alrite man difficult question, there is no easy way to determine the number so I really don't know. But if you really want a guess and not the exact, I'd say 10-15? if you really want to know, you'll invest in something that will allow you to know, otherwise its only a guess.
