Well positive reagant testing indicates the right identity but doesn't proof it. I have no means to know for sure wether what you got is 2C-B-Fly or not and
as long as you haven't performed some kind of chromatography or a NMR analysis on your sample you can't know for sure either.
So if you still have some of your 2C-B-Fly left please send a few milligrams to wedinos or energycontrol for further testing.
Doubt and submitting for lab analysis to make sure are always smart handling these substances, though in this case let's look at the information we have: her Marquis test was consistent while mine wasn't, indicating different batches. Her yellow reaction, when cross checked
with this, shows these alternative possibilities:
25C / other 25X - oral efficacy difference
2C-P - timeline mismatch
2C-E - *could* be consistent, although seems like effect mismatch
2C-D - duration mismatch
several tryptamines - duration mismatch
butylone and other cathinones - effect / drug type mismatch
DOM / alkyl DOX - duration / effect mismatch
While I encourage Kishka to have hers tested, right now it looks like there is one batch with consistent results and one batch with inconsistent results.
Otherwise think about it: they had a fake 2C-B-FLY with the right Marquis reaction, then switched that for a fake with the wrong Marquis reaction? I don't think so. If they werent duped themselves it seems more likely that after verification of the right stuff they try to make more money with a fake, riding on the legitimacy of the first material.
Since I have to leave my home soon it's difficult for me to invest time / energy in this, but hopefully next thursday I can have some of mine lab tested, it will still be probably multiple weeks before I have the results..
Anyway my theory is not meant to be a substitute for actual lab tests @ Kishka
