You're a newbie, you don't need either of these. Creatine will help a little, but you don't need it. If you're working out correctly, you'll see hella gains no matter what. Just remember to eat! A ton!
NOXplode is a nitro supplement. It'll give you more energy during your workout, and some claim it increases strength (on a short-term basis, i.e. 1 hour). If the claims are true, the benefit of nitro is the ability to do more cellular damage to your muscle tissue per work out; this could help you build more muscle faster. Other than the intense amounts of caffeine in NOX boosting your energy, I've found that the muscle-building effects are likely placebo.
The effects of creatine are way different. It coverts to ATP in your body, giving you more energy during a work out. It helps retain water in your muscles, thus giving you a semi-pump even when you aren't working out. It helps shorten the recovery time between work outs. There's been a lot of scientific research on creatine, and it has proven to be one of the safest and most beneficial supplements you can take (even beyond its application to bodybuilding). Just make sure you drink a lot of water or you could suffer from dehydration.
I've used both. NOX did nothing for me other than boost my energy and deplete my wallet. Creatine, on the other hand, has done everything it's claimed to do. Using it on and off, I've gained a good 60lbs of muscle over the last 4 years. Though this has less to do with supplementation, and more to do with diet and extremely hard, persistent work. There is no supplement that can replace hard, persistent, consistent work.
Drop the NOXplode. Buy some creatine if you want. Either way, since you've only been working out for 2 months, you've got a good 4 more months of newbie-gains to make. Good luck!
