My doctor put me on letro for 3 straight years due to gyno, high estrogen and low IGF-1. he had me on 2.5mg per day which seemed high but he is my endo and i trusted him. my sex drive is gone and i haven't had sex with my wife in a year. anyway i want off this stuff and now he wants to put me on hcg. i guess i want to hear what you guys think.
