when we see the final products at the shelves at GNC, then we can cast final judgement.
I do prefer powerful names...like monster, redbull, 5 hour energy, muscle, iron, chrome, nickel, mustang, combat, assault (not too crazy about it, but it's powerful), etc.
Hardcore and Oxysport kind of say nothing..The word hardcore was overused by porn industry in the 90ties and the word Oxy is being overused in cleaning products.
WARRIORS is a good name, along with hundreds other powerful names available.
