The coroner has spoken
I completely agree
The new ingredients of Jack 3D "ENOS Super Performance System"are L-citrulline, arginine and nitrate . A weird combination of substrates, precursors and products of the enzyme Endothelial Nitric Oxide Synthase (hence the ENOS). As someone who has written a scientific review on this enzyme with over 2,000 academic citations (http://www.biochemj.org/bj/357/0593/3570593.pdf), I wish supplement companies would just leave my field alone and find somewhere else to go to peddle their non validated concoctions.
A bit more of a rant than usual I'm afraid, but this death was so unnecessary....
 Nitrate can have a performance effect but you can get it cheaper by eating a lot of vegetables (or drinking beetroot juice).
