I got some samples in the mail when I ordered from nutraplanet the last time. Infact they hooked me up with a shaker, a t-shirt, and all kinds of samples. So I decided to give this stack a try, as they sent me samples of both.
Info on the products here
RPM is a pre workout stim
Drive is ... well ... ummm ... a lot of shit I guess
Per the instructions on the package, I took 5 RPM caps, and 3 Drive caps 45 minutes prior to working out.
Results:
Within 30 minutes I could feel the RPM kick in, there seemed to be a lot of caffiene in it, my heart felt like it was going to jump out of my chest, and not in a good way. within an hour I felt like I was going to puke, perhaps a pro/carb shake before hand was not enough. I had to enlist the help of other "suppliments" to calm me back down when I got home.
As for Drive, I really cant say, from the info its suppose to do alot of different crap, such as SHBG binding, increase LH, icreased thyroid activity. But It would appear to benifit from those things you need to take it for atleast a month if not more.
I wont be purchasing either of these, but if you get samples judge for yourself, and if you have questions please let me know.
