Pat E
Got this as part of M&S' last 9.99 mystery preworkout sale, For 9.99 it's fine, but I wouldn't consider it even if it costed a penny more. For something labeled "extreme energy" it doesn't even compare to BSN's Endo Rush, Kaged's Pre-Kaged or APS Mesomorph which are all in my usual rotation. The flavor wasn't bad, but I would say C4 is still a preworkout for beginners. If you're an intermediate to advanced weightlifter save yourself some money and buy Endo Rush or pony up a little extra for the Pre-Kaged would be my advice.*
