creatine is a waste of money.....red meat, milk, and eggs do the EXACT same thing, and give more bang for your buck.......no xplode is a waste of money....really, no2 in general is a waste of money and isnt gonna contribute to long term progress, some no2 products enhance a pump, that is about as useful to growing muscle as jerking off. If you want a boost before a workout, drink a strong cup of coffee, actually, forget the coffee, I didn't need a boost when I was 17 and neither should you.
protein powders are fine....they aren't magic....they are what they are....added dietary protein.
GNC is a ripoff, their prices are jacked up 20-50%
Worrying whether 5g of creatine preworkout is good or if noXplode is good preworkout isn't gonna get anyone big. If you want to grow get the words creatine and NO2 out of your vocabulary, lol...... Most people can't grow because they fuck up the easiest part of this that comprises about 99% of it, just eat more cals than you burn, eat lots of protein, get good at squats, deadlifts, bench presses, rows, and chins.
What I mean is, that notebook that was suggested you use to track progress will get you a whole hell of a lot bigger than any supplement ever will. There is no secret, no magic, just eat and get good at lifting.
