Deca cycles need to be longer. At end the sust will fade away but that suppressive deca will still be there. Impotance and low libido are the results of that.
I dont like sust period, way too hard to manage, that stuff is all over the place with all those esters. That deca dose is too low to do much good also, if your gonna shut yourself down you may as well do it right. Also run the nolva at least 4 weeks at the end.
1-18 test prop 150mgs EOD
1-14 deca 400mg EW
Nice and simple, eat, train hard, sleep and grow
