HCG Dosing If Not Commenced at Beginning of Cycle

I did some testing for the lab section, and HCG was not permitted, as it might mess up the lab results. Since testicular shrinkage occurred right away, I did not worry about starting HCG. Now, a month before the cycle is to end, what would be the correct way to dose HCG?

I was thinking 500 i.u. x 2 a week?

Thoughts?

Is the dosage different for people who have not been on HCG since the beginning of the cycle?

I think thats a good dose
