Its available through some HRT clinics. Its made in compounding pharmacies. There is no ester attached, so you'd be injecting everyday or every other day. It comes in 50 mg/ml vials, 10 CC's. Its expensive.
I wouldn't mind doing it every other day and then on the days off doing oral Anavar, see how that goes. I know one guy who takes it and likes it. He's very lean and muscular.
