Oh yeah I remember UO. A lot of the school athletes drank the hell out of it. Ironically, one of the "ginger" players who was on it was the first one in our age group to break 300 on the bench. But of course, take that for what you will.
Even back then I kept things mostly simple. Could buy ephedrine cheap all day OTC anywhere. I took so much that I was told about 5 years after graduation that E was the cause of my two gargantuan kidney stones that had to be broken up into dozens of pieces each so I could pass them.
