I'm not sure if this will work so maybe someone that knows more about how the HPTA is shut down will add in. But, how about your friend doing a very heavy cycle of primarily test, then say 3-4 weeks after his cycle is over he gets a blood test from the doc? Perhaps his HPTA will be shut down so hard that the doc will see lowered test levels in his blood serum. And then prescribe him some test. I'm not sure if that will work though. Anybody know?
When I 1st read the title of the post, I was just thinking "why would you want to lower your test levels."
