I tried this out to see if it made a difference and it most definitely did. Apply the Lipo-derm Ultra then grab a couple tufts of the RK and just slap i right on the skin and rub it in, i only put my shirt back on till this all dries, doing t this way made a noticable difference in potency then simply mixing in the RK. Give this a shot everyone! I've done this on obliques, abs, chest and triceps, i'm still using this on my cut it's excellent.
