I love my pre-workout supps and have tried them all. NO-Shotgun is the best one I have ever tried. Energy, focus, and pumps are all in check. I get no crash and no jitters from the energy blend which is awesome. Just for an FYI here is what I consider it better than:
NO-Xplode
Vasocharge(and I loved this product until I found Shotgun)
WTF Pumped
Superpump
Cold Fusion EX
Smash
Ragnarok
Xpand Energized
MHP Trac Extreme
Animal Pump
Hypershok
Shock Therapy
I'm sure i've used some others, but I just stockpiled 8 tubs of NO-Shotgun while it was BOGO. Taste isn't that great, but man up and drink it. I'm using v2, but am getting a bunch of sample of v3 for comparison.
