The FDA has deemed DMAA to be unsafe, which was an ingredient that was considered effective in the original Jack3d. USP Labs intially fought the FDA to try and keep DMAA on the market, but in the end could not win the fight.
So what does this mean for our beloved Jack3d and the other preworkout supplements? USP Labs has vowed to make the new Jack3d Advanced formula better than ever and hopefully they will bring it! If there is a company out there, that will look for innovative ingredients, its USP Labs. We will have the new formula in soon, so sit tight and we will see if its as good as the original.
