There is a nice read on ncbi about using HCG for a restart after anabolic steroid induced hypogonadism...id post the link but....so you will have to search to read the full text.
Anabolic steroid induced hypogonadism treated with human chorionic gonadotropin.
Abstract
A case is presented of a young competitive body-builder who abused anabolic steroid drugs and developed profound symptomatic hypogonadotrophic hypogonadism. With the help of prescribed testosterone (Sustanon) he stopped taking anabolic drugs, and later stopped Sustanon also. Hypogonadism returned, but was successfully treated with weekly injections of human chorionic gonadotropin for three months. Testicular function remained normal thereafter on no treatment. The use of human chorionic gonadotropin should be considered in prolonged hypogonadotrophic hypogonadism due to anabolic steroid abuse.
