At the moment best option is injectable testosterone- either test e or cyp (whichever is available in Canada both), you start with around 100 mg a week and work your way up or down, on top of that I suggest HCG 3X a week, 250 IU to start with, 50 mg pregnenolone and AI- preferably exemestane/aromasin- dose of AI depends from person to person.

BTW restart protocol rarely works for people close to 50 and over.
