USP Labs released their highly anticipated follow up to the original Jack3d with Jack3d Micro, late last year. The formula introduced the ingredient higenamine, that has now been used in more pre-workouts than we care to count. On top of the ultra concentrated product, USP launched another pre-workout supplement only a few weeks ago called Jack3d Advanced. Despite the surprise release of the product, the brand did say that the Advanced formula was not going to replace Micro. This has been further confirmed with the production of two new exclusive flavors for the supplement. Joining fruit punch, lemon lime, and blue raspberry, is GNC’s green apple and Bodybuilding.com’s sour cherry. While the two additions are both exciting, it would have been nice to see something a little more creative. As the two are the exact same flavors the retailers had as their original Jack3d exclusives.
