I have gone through several bottles of Drive. RPM is great once you get the dosage right but I can't say that I got much from Drive. RPM is so effect on it's own stacking with Drive seems unnecessary, moreover it is difficult to tell if Drive is even working. Therefore, I used Drive as a standalone. I works to a lesser degree than RPM but it does work if the dosage is high enough. Both RPM and Drive are underdosed so be prepared to use higher dosages which increases the cost. |
