I am 100% fan of the same blend ldog is referring to. It has the Mast P added in and it is amazing. I recently tried running a blast of long esters (deca, Mast E, and Test Cyp.) Never again will I stray from GC's blend of TPP/NPP/MastP. It is clean gains. None to very little pip. Strength, Mass, Libido.... Everything. All in one nice little package! I will actually be ordering some more of this SOON!
