I guess you can say i front load in a way,, I start every test cycle out with sust. then switch to whatever i am going to run, e or cyp... I would rather do it that way then just use straight up prop, seems to work alot better for me... then again we all respond differently.. but that is my bread and butter... with my other baby eq
*** forgot to add that i will run the sust at a higher dose then i will the test e or cyp, if i am going to run 500 test e and 400eq -- i will start sust at 700-750 eq at 400 just for 2-3 weeks then switch over and cut it down..
