I just came off of a 40mg Var only. Sustain is working great for me right now. I did stack the Demacrine with the Var and it did well. Like most people say, I kept about 90% of the strength when I came off . I have a few more weeks and then I am going back on. Sustain is good stuff bro. Great for my track workouts as well as weight room. Definitely get some.
