Where in Southern California? How old are you? Do you have low test #s?
If your in LA, Holtorf Clinic is like pay to play, they will rob you blind in costs, but essentially if you have money and any symptoms or bloodwork to back it up, you can get your goodies, at least T, HCG, GH...not sure about AI....
Dr Shiva Lalezar in Santa Monica/Brentwood will do creams, and if you push her she will do injections, but I think in office and might be the once every two week thing, she is heavy into the creams...but will give you and AI and HCG if needed...
Dr Robert Krochmal in Woodland Hills, he will give you Test and GH if you need it AND your bloodwork demonstrates it, and if you have good reason or high estrogen numbers you can talk him into an AI I bet, and if you are worried about fertility talk him into HCG....very open minded, you just need to have the symptoms, and know what you want, and how to back up what you want with him...he is a sort of guru of working with folks who have problems that traditional doctors mess the bed on...depending on your size and background he is progressive on doses
or there are those online clinics guys are members of here, you skype or do labwork locally and meet a local doctor but your meds get shipped from a Pharamacy in Florida or something...
Sounds like you need to do WAY more research if you are generally asking what to do...and what to say....you need baseline bloodwork to see if you are even going to be in the ballpark to ask...and you need to look up the symptoms and see which you have, so you know what to go into the doctor complaining about....
