RE: Pre-Workout boost needed ?
AMP - strong stuff
Stim X - not tried it but heard many good reviews
Venom - not tried this but agian heard good reviews, some report a crash.
Powerfull - not a stimulant as such but i find it gives me a definate endurance boost and mental focus - stacks very well with AMP.
Livertabs - again not a stim but again helps my performance.
Heat - more of a fat burning supp but ehances prolongs effects of AMP.
With the likes of AMP / Heat do not use if your using SSRI's or MAO inhibitors etc.
