This preworkout supplement definately will give you the stimulation for a good workout. The only down-side is the taste. The new version (3.0) has a carbonated taste to it and its like taking down champagne which is not a typical taste you expect from a preworkout. That is why it is suggested to stir the product and not shake it! Apart from the crummy taste it does have good effects and sustained energy without a sudden crash. I keep a tub in stock to alternate with the other preworkouts that I use some days in the month.
