Medical literature produced by the staff of pharmaceutical companies (medical writers, MDs, pharmacologist, scientists) is better than any of the stuff you'll find here and it's given to you for a reason along with your purchase.
Doctors prescribe medicine, not us.
Medicine is used for medical conditions.
How am I an asshole for suggesting you read product literature and see a doctor for medical treatment and for not treating the use of medication as some sort of take-or-leave-it sort of activity.
Just you asking how long can it be taken would give any well informed person the assumption that you don't even havve a medical condition that warrants the use of Androgel.
How long can it be taken by hypogonadl men? Forever.
What are clinical dosages? 5, 7.5, and 10 grams per day.
I took Androgel for nine years, used Testim this past month, and will get Testopel implants next Friday.
