I found I made my best results from Sus250 going two shots a week, 250 mg. per shot (so500mg. per week). Sus250 is by far my favorite test. Great bodyweight, size and density gains overall. I've now tried all the various tests, and Sus250 remains the best for me, even pre-contest. Because of the longer-acting esters, you'll probably keep making gains for about a month after you come off it, thats what usually happens to me.
