I know that it is recommended that you only run test for 12-14 weeks at a time, but i know a lot of people have run it a lot longer.

My question is what happens if you ran it for a long time? Is the risk that you will shut yourself down for good? become infertile? heart disease?

I find it funny that women run estrogen (birth control) for tens of years, go off it and get pregnant right away. Why aren't men able to kick start test again after years of use?

What are the longest runs of guys on here? did your levels come back?
