DHEA, Tribulus, ZMA Stack?

Hi, as I posted in the over 35 subforum I have low testosterone and am looking to bump it up. I’ve been taking tribulus and ZMA for about two weeks now and can already feel a boost (libido, concentration, some energy). I finally talked to my doctor about my test and he suggested I take DHEA. The thing is I’m only 30 yrs old and my DHEA sulfate number seems to be fine.

I suffer from an anxiety disorder and anxiety is supposed to wear down your addrenal glands and DHEA is supposed to help this so maybe it would be appropriate for someone in my situation?

Here are some of my test results (pre ZMA and trib)
Testosterone Total 182 (horrible I know)
Testosterone Free 51.9
Testosterone Bioavailable 120.4
SHBG 7
Albumin, Serum 5.1
DHEA Sulfate 433 (110-510 is range)
FSH 1.7 (1.6-8.0 is range)
LH 2.5 (1.5-9.3 is range)
