My doc prescribes for my hypogonadism . . . says to take the test enthanate (200 mg) for 10 weeks, then 2 weeks after the last shot:
10 days of 1000 units HCG per day (insulin needle)
10 days of clomid starting on the day of the 5th HCG shot
wait 4 days after the last clomid, then it's time for a blood test, then start up the test shots again for another 10 weeks.

Thinking of adding a little bit to these numbers, though, in a few months . . . see what happens . . .
