I totally thought it was untested back when I did it, though that was 6 years ago. And one of the few things I read about it in terms of studies was its effects on army pilots during 12+ hour training sessions here: http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA533725 http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA533725, hence why I thought it was an army drug. Learned something new today.
