i have done 2c-e at 15 and 20mg (often with boosters of 5-7) and i would say they boath would be ok at a party. In my opinion 2c-e is a better drug for a nice trip at home as where 2c-i would be better for a pary due to its stimulating effect. the "right dose" for everyone is completely diffrent, i know people who trip hard of 15 as where others prefer 20-25. just be safe, be carefull, and be smart. Peace, Mike
