Hello guys. I could really use some help please!! Here's my story. I am 28 years old, have always been an overweight guy up until the last year when I lost about 65 pounds.

For the last 5 years or so, I have been battling with severe fatigue, tiredness, lost of concentration, short term memory loss, etc... I have seen around 6 different doctors who had me do all sorts of test and nothing. Finally a friend of mine told me to go get my T level tested. I went to a local TRT clinic and sure enough I was at 136 ng/dL! So they started me on 100mg of test cyp a week, plus zinc. I started feeling a little better but nothing great. Well now, 3 months later and I still feel like crap. I feel as if im getting dumber sometimes. I forget to spell certain words, my memory sucks, I feel like crap. At this point I don't know what else to do. I am on 180mg of test cyp now.

Here are my labs. Please give me some advice. I am so sick and tired of being tired that its actually giving me depression. I would appreciate any help. Thanks

Was given the Anaztrozole right after this lab came back due to higher Estrogen levels. .5mg twice a week.
Also started HCG twice a week.

8/2/2012:

Prostate Specific Ag, Serum: 0.7 ng/mL (Reference Interval 0.0-4.0)
Testosterone: 445 ng/dL (Reference Interval 348-1197)
Sex Horm Binding Glob, Serum: 12.8 nmol/L (Reference Interval 16.5-55.9)
Estradiol: 17.5 pg/mL (Reference Interval 7.6-42.6)
Hemoglobin: 16.7 g/dL (Reference Interval 12.6-17.7)
Albumium: 4.3 g/dL
Free Testosterone: 14.3 ng/dL = 3.13%
Bioavailable Testosterone: 334 ng/dL = 73.4%

So as of now I still feel really crappy. Please let me know what you think. Could it be that my estrogen went down too much? And what is SHBG? Mine is low, it looks like it.

Any help would be greatly appreciated.
Thanks
