free testosterone

My total testosterone is 886 ng/dl (900 is the top of the ref range), shbg = 67.67 nmol/l ( 18,30-54,10), albumin = 5.3 g/dL; I also tested my free testosterone and the lab result was 12.0 ng/l (8,30-40,10). If I convert it to ng/dl, that will be 1.2 ng/dl. This means that my FT/TT = 0.14%...

Sorry to "short-cut" reading all the posts here, but I don't know much about Testosterone and get overwhelmed quickly. What I'd like to know is (I had Radical Prostatectomy last June) what are the symptoms of low T? I've had fatigue, depression, less than ideal erections (Viagra worked well...

My question is should I be concerned about having high Free T levels that exceed normal range both in total (23 pg/ml) and percentage (2.7%) ? Since moving to injections I have done two blood tests (not ideal times but based on travel to US where I can order my own test through DiscountLabs)...

In follow up to my earlier post regarding my saliva tests, is it even humanly possible to have a Free Testosterone level of "2000 pg/ml" ?

I did a scan for this but didn't see anything has anyone noticed an effect of HCG on their Free Testosterone ?

For those of you who switched to sub q, what has been the impact to your Total T, Free T, Estradiol and DHT ? Thanks !!!

Fatigue is can be very frustrating for many people since it can have several causes. There's the normal tiredness we feel at the end of every day, the tiredness that comes from being a hard-working person. But sometimes that fatigue goes beyond just the "norm". It pervades your muscles, fogs up...

What concerns are there for having high Free Testosterone scores above the normal limits after two months of TRT when Total T, Estradiol, Hematocrit levels are all as expected? What are the next tests to consider if any?

Hey guys, So I went to a doc two weeks ago that specializes in TRT. A little background on myself. I am 25 years old, 5'11" and 190 lb. When I was around 20 years old I started messing around with pro hormones and steroids without looking at the later consequences. As of the past 2 years my...

It has been traditionally thought and believed that sex hormone binding globulin (SHBG) is more or less correlated to estradiol (E) levels and the amount of free testosterone (FT). Free - testosterone is the portion of testosterone (T) that is available to enter a cell and bind to the androgen...

As shown in the figure above, about 2 percent of the testosterone in the body is active. This “free testosterone” is not attached to binding proteins that would prevent it from interacting with its receptor. About 40 percent of the body's testosterone is attached to albumin. This is a protein...
