I am looking into a pre w/o stim/supplement and was wondering if anybody had any insight into these two products?
Never used R4W, but almost always use RPM.
I have used both the original and reformulated versions of RPM and have dosed everywhere from 1 cap all the way to 6 caps. Whilst on the original formula I had to dose pretty high, on the one out now I only need 2 caps to get optimal effects.
Although classed as a stimulant, those that expect RPM to act like a stimulant and give that jittery "stimulant-like" energy will be disappointed.
Personally, RPM provides me with a smooth, focussed energy (as opposed to jittery, restless energy). In the gym I am calm and almost RELAXED. Training sessions seem to move in slow-motion, and sometimes I cannot believe that an hour has ALREADY passed (when it seems like I've only been in there for a few minutes). Being an aggressive person by nature, on RPM I can amplify that aggression and channel it into my training, thus providing me with better quality sessions. RPM also adds just that much more to my pump and vascularity: The pumps are great, and are painful at times, with vascularity ropes and knots of blue snaking up arms and legs.
It would also depend on whether you were looking just for a preworkout stimulant, or a product that had other effects. RPM, for example, also has thermogenic and testosterone boosting properties, as well as helping increase strength.
