Hey guys, hope you don't mind me dropping some information here.
First, the OG Jack3d is still available in the US, but mostly online. As a disclaimer, I DO sell it - I help run . We're teamed up with the PricePlow.com engine to give people good deals (like the post mentioned above).
Second, Jack3d Micro definitely has different stimulants than the OG Jack3d. They're not as crazy strong, but they last.... and the pump ingredients make up for it bigtime. I'm a huge fan of the main 3 NO boosters - they hit you in phases throughout the workout.
That said, people who want to get 'stimmed' outta there minds or have a high stim-tolerance are not going to like Jack3d Micro as much. There's just less caffeine and intensity in there for many.
So if you're in the US, the choice comes to pump vs. energy. Micro has more pump, OG has more energy.
But the point is that Jack3d is NOT currently banned in the US, but some stores stopped carrying it after other countries banned it.
There's still ongoing stuff behind the scenes with the FDA and what they're going to do with DMAA (1,3 Dimethylamylamine - the ingredient in question). USPLabs, manufacturer of Jack3d, just submitted another study showing that DMAA is naturally extracted from Chinese geranium, and thus should still be permitted as a natural ingredient. I'm sure there's more going on, but that's the latest news on that front.
Anyway... if overseas, then you'd have to just go with Micro or try other high-stim products.
Good luck, hope you don't mind me barging on in here.
