I have used a number of pre workouts over the years (Craze, Frenzy, 1MR, SuperPump, Black Powder, Jack3d etc) and while I find Craze and Frenzy the best I have ever had, this is now my preferred choice. Craze and Frenzy were quite full on and are now banned in many places such as Australia (and came with side effects) hence I have moved to C4 as my choice of pre-workout. C4 provides a good pump, tastes great (Preference is Blue Raspberry!) and minimal if any crash. Not the cheapest but I find it reasonably priced. My positive experience with this product comes from responsible use (e.g. cycling on and off pre-workouts, not overdosing etc.)

C4 Extreme is one of those supplements that everyone should include in their supplementation program. The energy, pumps and mental focus that C4 provides will take your workouts to new levels. It comes in a variety of flavours; my personal favourite is Icy Blue Raspberry.
