I could care less about the NO, I was referring to the stimulant/drive from the product. So it's a better idea to take them for a few weeks and then take a week off. Your body builds a tolerance extremely fast to stims, or at least mine does.
Good product no doubt strenght wise, but it relaxed me so much when i used it that i ended up gettting damn sleepy before my workouts were over!! Unlike most guys i know that tried it and always felt energetic... I think geranium works much too well on me... lol
Only thing to do is to try it for yourself and see how YOUR body react... chances are you'll be super charged like the vast majority of users.
the original was freaking awesome.. didnt notice much for NO but definately a GREAT pre w/o stimulant. the new formulation is JUNK imo.. 3 scoops to get the same effect of the originals 1 scoop at the same amount of servings/tub.. i'll stick to caffeine pills..
I use it and love the product and it definetly works but just like any other stimulant over time it looses its affect. I like to take breaks from on occasion but its one of the best ones i've tried. I hear a lot of good feed back on 1RM product and i thought it was crap compared to jacked.
