Meh. IMO, there are a lot better. Even the energized version barely woke me up. There are definitely quite a few, well, just a few, better NO2 supps out there. I'm loving horse power right now cause of the beta alanine... no-shotgun for sure, plasmavol is ok and without arginine, etc. Others speak highly of p-slin, wtf pumpd and others so check it out.
