Is it possible for an ectomorph like myself who has been training naturally with the exception of creatine/andro/whey protein for the past 4 1/2 years to make solid gains i.e 10-15lbs taking 250mg of sustanon a week for 10weeks??? I'm 5'11 right around 180lbs. I eat pretty healthy and I get a lot of cals but I can't seem to put on much mass. would 250mg be sufficient for a first time user to AS?
