Im doing test e on my first (proper) cycle,but that takes a while to kick in properly so for the first 4 wks im running dbol with it,it might be the same with sust,i wouldnt do your cycle like that.i would run it for 12weeks
1-12 250/500mg a wk

if its 250mg/ml and your only putting 1ml a wk into thats quite a low dose so that might be why you havent really noticed anything either.
