this is a fairly new supplement by Gaspari Nutrition, I have been an advocate of an NO product called NO3 overload and have tried everything but the new AMP NO supplement(which Ive also heard good things about). I used the Plasma Jet last night and OMFG the initial pump was good, then the middle of my workout WOW...this was at 830 last night. Right now at 10am I have the most wicked pump ever! thsi stuff lasts forever apparently, so I read the box and it explains how the effects an last up to 32 hours! highly reccomend it!
