How can a person tell if what they have is 2c-e WITHOUT a testing kit OR a taste test? Any way you know would be needed!
To my understanding, it would have to be a lab test and that would be possible, there are places to have a ms test done but off hand I don't know of a link and don't know that it's kosher to post even if I did. Really though, an acid test followed by a taste/allergy test ought to put your mind at ease. If you did your homework before sourcing, you'll be good to go.
Mix a teaspoonful of human urine with 4 drops of iodine and some table salt (NaCl). Drop it over a small mound of your sample. If your powder is a 2c the mixture will turn tangerine-orange.
