If you have low test levels, maybe you could do "cycles" of nolvadex and maybe some clomid as well. Do one month cyles with two to three months break in between. It seems to work for me. My balls are at least 10 to 20% bigger, I'm hornier and have normal sexual function compared to last year when I noticed I was starting to have issues in that area.
I had three blood tests last year because of this issue, the first test showed that testosterone was below the normal range (though the night before I drank alot of alcohol and only slept a few hours). The other two tests came back low normal testosterone. I feel that doing these PCT's have probably brought my test levels up to the middle of the normal range. I'm going to retest my levels at the end of the year to early next year to see where I'm at.
Also, try to do other things that improve test levels naturally, such as getting a solid 8 hours of sleep, eating adequate calories with a decent amount of fat, get all your vitamins especially zinc, don't let your bodyfat get too high (increases estrogen which lowers testosterone), get a good amount of sunlight or bright light especially in the morning, fish oil, don't train hard every day it will lower test levels (it's proven by many scientific studies).
Here is a message on another forum from a guy who tried various methods of hormone replacement therapy and he recorded his test levels every month or so, check out his test levels when he went on the nolvadex only protocol, and also his comments, it is a very interesting read....

I forgot to mention that I've never taken any steroids in my life.
