I received RPM and Drive a while back but wasn't able to give it good try. This morning I took two RPM and 1 Drive, I also took 2 servings of NOS Ether. Now I know many may say that by taking Ether my results may be skewed but I haven't been in the gym for 2-3 months. And I'm really impressed, I hit chest and amazingly I was able to do high volume, drop sets, etc. I attribute this to the AN combo the strength gains w/ ether affect me w/ time. This was pretty much immediate results. Again, very impressed. Oh, thanks to AN, I asked for a sample and it showed up in like 3 days, couldn't believe it.
