Thread: Supplement Ingredient DMAA Is Illegal, Dangerous, FDA Says

I built up a tolerance to this stuff pretty quickly, hopefully the next compund they introduce will not be the same.

I never liked this supplement it showed too many signs of a dependency developing.

GOP questions stimulant use in dietary supplements

The House Energy and Commerce Committee is launching an inquiry into a potentially dangerous stimulant used in dietary supplements sold by General Nutrition Centers (GNC).

Top lawmakers on the committee sent a series of letters Wednesday to federal regulators, GNC and USPlabs, maker of a dietary supplement known as Jack3d.

The powder is marketed as a workout enhancer and contains dimethylamylamine, a synthetic drug linked to several deaths.

In a warning last month, the Food and Drug Administration (FDA) urged consumers to avoid supplements containing dimethylamylamine, or DMAA, because the drug could trigger heart problems.

GOP lawmakers are now asking why USPlabs continues to use DMAA in Jack3d, and why GNC is still selling the supplement.

Reps. Tim Murphy (R-Pa.), Joe Barton (R-Texas) and Michael Burgess (R-Texas) also asked the FDA to detail its efforts to remove DMAA products from the market.

"The agency said that 'FDA can also take a seizure action to remove the products from the market or obtain an injunction against a company to prevent it from manufacturing and distributing illegal products,'" the lawmakers wrote.

"That being said, as of May 7, 2013, USPlabs continues to market Jack3d and General Nutrition Centers, Inc. continues to sell it."

Lawyers for USPlabs have said DMAA is legal, and that the company should be allowed to use it.

I bought a bottle of dmaa pills and caffeine pills. I don't use them all the time but I loved the original jack3d. I only take them off cycle on random days.


I heard people were doing higher doses to get off (like posted above, similar to MDMA) but I haven't tried that yet. Maybe if I get bored this weekend. I've only done 20mg with 200mg caffeine pill.
