I know that a lot of you aren’t particularly interested in DMAA, nor do a lot of people consider it a Nootropic, but for the rest of you, DMAA has disappeared from the marketplace. I wasn’t paying very close attention to this compound, so it’s actually been a few months since its disappearance.
DMAA, also known as Methylhexanamine or Geranamine, has come under scrutiny due to an incident in which two U.S. soldiers who died when they collapsed during physical training using the drug. These deaths happened in February, 2012. Due to this incident, the military began investigating the compound, which eventually lead to the FDA issuing notices to all manufacturers of the drug in April 2012. http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm302133.htm
This means that all of the food products which contained DMAA have now been pulled from the shelves. It’s no doubt still available in bulk powder from sources not labeling it for human consumption, but it is no longer to be found in terms of supplements.
Edit: I was corrected on reddit.com/r/nootropics – JACK3D is still being sold with DMAA in it. All other products seem to have been reformulated or taken off the market and it is very difficult to find DMAA powder.
