What in general to expect from Rag you ask?
Only a grade A pre-Wo formula at its finest. It depends whether you get the caffine version, or caffine free version. Either way you are in for a nice pre-wo that offers great pumps and energy. The caffine free version gives you a nice relaxed pump yet great focus and explosive energy to use when you desire. I would compare the Caffine Free version to RPM in effects. I did not become tolerant to it either.
-Compares to the pump of Super Pump 250, with out the sides
-tearing up the weight room
Caffine Free Version
-compare to RPM
For me I get pumps almost instantly and naturally. Both versions however offered good pumps and blood flow. Vascularity was def visible as always!!
Lasted the whole workout no problem. I felt like i was still full vascularity and muscle wise after the workout. Its not one of those pumps that fades as soon as no more weight is touched
All in all i give it a quality review and a great Pre-wo formula thats safe, effective, fun!
