Just a couple of things:
50mg of waxy maize? WTF? Of course I know the reason it's there - just looks good on the label.
Same deal on the citrulline (6000mg might increase endurance, but 50mg?), betaine, glucoronolactone and several other ingredients. Doses that do nothing - just label filler to fool the customer.
Creatine Ethyl Ester - proven to not work in research.
Arginine - hasn't been shown to increase nitric oxide in humans via oral delivery. The "pump" from this is imaginary.
Only thing useful I find in there is the caffeine. 200mg, same as a strong cup of coffee. No hating, the formula is just shit.
There are studies that have proven Arginine does support the increase of blood flow to skeletal muscle.. I'll have to disagree with you on this. It is still a new substance that is being researched, but I wouldn't go so far and say the pump is imaginary, granted I'm sure many people over exaggerate it, but it is there and noticeable.
Yes the Caffeine is effective, so is the creatine included, the Beta-alanine, and the Tyrosine and of course the Arginine.
I know the Waxy Maize does look funny at a small qty like that, but I believe its there as a means to control the texture of the product itself. Its not meant to be there for your pre-work out carbohydrate intake!
Dude its a good product.
I've taken other products some I've liked and some i haven't liked! But this is the one that I've liked the most!
