If you have ever picked up a muscle magazine, then you have seen an ad for BSN No Xplode or USP Labs Jack3d.
If you have ever been to a gym, I bet you have heard the guys talking about No Xplode vs Jack3d, which is better?
In short, both supplements provide energy and ingredients to increase the focus of your workout and help build muscle. In my opinion, the winner is NO Xplode. For a better understanding why, see the NO Xplode review here. The one ingredient that separates NO Xplode from Jack3d, is creatine.
If you are not familiar with creatine, it is the most common bodybuilding supplement on the market. It has been around for over 15 years and has more research conducted on it then any other supplement.
At the end of the day when it comes to picking a pre workout, the best thing to do is to compare the ingredients, price, and serving size. A great pre workout comparison guide is at - http://bestpreworkoutsupplementguide.net
