some info I got from blue light, helped shed some light.
Oh yeah, 21 ml of 190 proof everclear (26.5 ml of 151 proof for states where 190 is illegal) has the same amount of alcohol as a single shot of 80 proof liquor (such as most vodka, whiskey, rum, etc). Everclear has some advantages over other liquids such as distilled water or 80 proof vodka, such as better dissolvability in it, it's still drinkable (although it tastes horrible), the alcohol speeds up the body's absorption of anything dissolved in it, and it evaporates faster when left in open air (which could be an advantage or a disadvantage depending on your application.)

A few numbers. These are not _super accurate_ and were determined empirically for a saturated solution... but this should be useful as a general guide. You can't use these concentrations in practice (because you don't want it to crystalize out on a cool day), but this is a starting point.
Solvent was 20% EtOH (1:1 vodka:water mixture)
Temp was 75 F
2C-C ~100mg/ml (!!!)
2C-B ~45mg/ml
2C-I ~25mg/ml
2C-T-2 85~90mg/ml
2C-D ~100mg/ml (!!!)
2C-E ~70mg/ml
In dH2O, 2C-I slightly under 20mg/ml
In 40% EtOH, 2C-I ~50 mg/ml
2C-I takes goddamned forever to dissolve, no matter what you're dissolving it in. Others go into solution much faster.

found plenty of reports of 2ce dissolved at 20mg per ml, and a few of 2cb..
