Its not HMG, he is referring to GnRH. Its stimulates FSH secretion which in turn will return testiclar function, fullness, and will do that job if HcG has not. HCG only "simulates" LH function, GnRH actually makes your pitutary function and secrete which will in turn make you "recover". GnRH has been used for a long time in horses to help them become fertile.
I know where to get it, idk if I can post it... but PM me.
