This is a broad question and the answer varies by age, symptoms and baseline testosterone levels from the patients blood work. Generally, the starting dose is between 100-200 mg weekly for the injectable forms. I typically start patients at 150mg per week and readjust the dose after new blood work in 10 weeks time. Rarely do I need to increase the dose up, and typically I don't need to change the dose at all. This seems to be a good sweet spot.
