Probably the most expensive Ephedrine /ephedra supplement I ever tried, but gosh it was good.
Ultimate Orange was Caffeine, Carb powder, and Ma Huang. It might of had Grapefruit extract also, but those were the big 3. The secret I think was that the dosages weren't really all that standardized, it was like you opened a few Diet Fuel bottles, uncapped the the pills, dumped them in the jug, and hoped for the best.
It was the best non-protein OTC supp of the 90's.
