No, it will not be that amazing candyflip feeling. In order to feel that, you would need to, erm, candyflip?
Lol. If you want to try it then try it, we are just advising you from a harm reduction standpoint. Chances are it won't be very enjoyable. 25i magnifies the sensory perceptions beyond belief; I could barely hold my shit together combining it with DPT, and totally blew out my gourd by mixing it with aMT. MDMA is more intense than either of the aforementioned chemicals imo, and as such the trip is likely to be very difficult to manage.
