Thanks for the move but we do not allow ID threads, so this is going to be quite short before it is closed.
1. Like I said, we cannot and do not know what compound you have that was provided labeled 2C-E - though you did not ask explicitly it is implied in your question.
2. Taste is not a proper measuring device, furthermore taste varies from person to person, even categorically from genetic causes. It's what may be called a quale: a data-bit of quality that is ineffable and essentially we could never communicate how something tastes. There may be consensus for example that 2C-E tastes more like 2C-B than like broccoli, other than that asking whether you can tell something by having the taste remind you has no point and no end.
3. As is said: be very careful. If you have tasted it, then I assume you took enough to reach some effect... or was a tiny amount dissolved in water? (That would allow for a solution with greater volume to be tasted more practically), if it was MDPV you should notice the stimulant effect instead of the psychedelic effect. It is quite distinct.
4. But if I tell you to carefully try it out for yourself - which you have already begun - build up your doses very very slowly and use a scale. There is no compromise on this unless you had access to someone else's scale and can use volumetric measurement.
I am going to allow you to respond to this, but like I said - in-depth discussion on an ID issue is not wanted or allowed.
