Professional Muscle is good however, often the comments don't really reflect the performance of either product very well because NO products are effective. That thread just has the same 3-5 people who are obvious NO haters bashing the products. Can you really guage a products performance based on that? No, of course you can't.
There are lots of bodybuilders that take NO supplements and there are lots that do not take them. Any method of training is effective as long as you work your ass off. When you're exausted and think you're spent, dig deep and keep going, that's where great results are at.
If you are looking for a "magic pill" so-to-speak and think you can take some NO supplements and do some half-assed training twice a week and think you're going to get ripped and bulk up, you're sadly mistaken.
It all depends on what results you are looking for and to what lengths you will go to in order to achieve those goals.
You need to take NO supplements in cycles so you can give your kidneys time to recover due to the high caffeine intake (12 weeks on NO Xplode or naNO Vapor and 4 weeks of training with no NO supplements).
I've taken both and seen good results with both but the results I'm getting with naNO have been even better including not getting an upset stomache like I do with NO Xplode and not having to take naNO on non training days.
They are both very good NO supplements and you need to consume lots of water while using them during training because there is a lot of caffeine in them (you're looking at around 100mg's per scoop of Xplode and 125 per scoop of naNO) and you can stack either one with CellMass for even beter results (take naNo or NO Xplode pre-workout, CellMass post workout and before bed).
The most important aspect of lifting though is form, if you're lifting weight to the point where your form suffers, you're lifting too much, never sacrifice form for heavier weight.
