i like San TIGHT , i got great results , but only when i cut carbs significantly
i also tried Venom too, the one with ephedra and i found it to be too intense, and i can drink ecsresso like water
my choices are
San TIGHT
Lipo 6 (not "x")
Jet Fuel
Use any while "cutting" as in carbs and increase cardio 15 mins over your average, you'll see results
