If your cardio is something in question and need a cycle to keep that up to par IMO there isnt much better of a cycle then test and EQ. Eq increases redblood cell count putting more oxygen into the blood thus increasing cardio and helping to get extra oxygen to the muscles. Test will give you some added strength and together both will add some aggression.


IMO if you are a sprinter you would stay away from anything that would add bulk or much mass.
