Special Forces soldiers between 0.8 to 1.0 mg per kilogram (mg/kg) of
ephedrine and 3 mg to 5 mg/kg of caffeine 90 to 105 minutes prior to various
exercise tests. These numbers translate to approximately 60 mg to 80 mg of
ephedrine and 239 mg to 398 mg of
caffeine for a 175 lb man-relatively high doses of ephedrine, especially
when combined with the caffeine intake ... Time to exhaustion during a high
intensity cycle ergometer test (at approx 85% maximal aerobic output)
increased dramatically"

of adverse effects, they didn't use an off-the-shelf supplement ... There
are many, many other ingredients in these supplements. It is not the same as
Metabolife or others. I really don't think you can use this as a study to
invoke the safety of dietary supplements. This is just not what people out
there are taking"
