Hmmm
I have done alot of research on the net on no-xplode and I will have to agree, it probably doesn't match the hype that the pro-sites and posts give you, but, I also want to take a moment to express something.
Most of the cons against the product follow the path of 'it doesn't work' and 'its a placebo effect'. Well, here is my way of thinking.
Basic Rule (For Me, Proven and Tested by Me): Muscle gain comes from good nutrition, lots of protein, consistancy, and pulling out those couple extra reps of those heavy weights you gave up on a few days before.
Now, if a product is safe and 'placebo effect' or 'no placebo effect' gets you those extra couple of reps and you start seeing results, then heck go for it (if you have the money). The 'it doesn't work' response needs to be followed with 'for me'. Because, even if it is a placebo effect, it IS working for you.
The question is, could they get the same results by not taking it. Well, if it is a placebo effect that is causing their gain, then a person stands the chance of losing that effect mentally when they quit taking it, thus lowering their mental strength.
Most bodybuilders I know will tell you that a good percentage of building muscle come from mental strength, its being able to push yourself to your limits, much like any sport.
Me 2 cents.
