I'm particularly interested in rampage.
Rampage is the biggest selling supplement we have ever had. Natural athletes/bodybuilders use it to increase thier natural testosterone levels without negative side effects. The not so natural guys use it as PCT at the end of thier cycle to get their natural test levels back up. Rampage is the ONLY natural test booster that will increase strength within 24hrs (some guys experience strength gains after 1 dose). Rampage has the highest level of the active ingredient protodioscin on the world market and this has been confirmed many times over the years in independent analysis's not performed by Urban Muscle.
Refer to the website for more tech info on how it works.
