The best way to go about it would be to add hCG and hMG to your protocol. However, hMG can be extremely expensive so it’s not used very frequently. There’s no doubt that hMG is the most effective drug available, but it’s cost has prevented widespread use in cases where it’s not covered by insurance.
The good news is that hCG alone has proven to be an effective fertility drug for men on exogenous hormones. If cost is an issue for you, you’ll still likely be fine even if you exclude hMG from your protocol.
If you’re going to use hMG, 75IU two or three times per week is a pretty standard protocol.
HCG dosing isn’t so cut and dry, but that’s ok, men have been successful with hCG within a pretty broad range of doses. 350-500IU three times per week is a good starting point. It’s an effective dose, but not so high that controlling estradiol will become too difficult.
Some doctors prescribe several thousand IU’s per week and while it’s effective at restoring fertility, it can sometimes make estradiol management a real chore.
I’d definitely go with ~1000-1500IU/week, and then get a semen analysis after a few months. Then you can adjust your dose if necessary.
