What is your total and SHBG?

What is your total and SHBG?

I didnt measure my total and shbg, with the range given is my free t considered low for my age?

Do a complete testosterone panel and then post your levels. No reason in just checking free T

There's little actual information to make an assessment, testing method, Total T and SHBG. If your testing method is the direct immunoassay, then the Free T results are worthless.

The equilibrium dialysis or ultrafiltration should be used for greater accuracy. Also important is what time of day were these bloods drawn. Men's testosterone peak in the morning hours, by 12 noon testosterone levels have declined and continue to do so into the evening.

Let's say these lab results are accurate, what you should be asking is are your testosterone levels consistently elevated and are these levels low for you.

The testing method is ELISA, the testing was done at 10:15 AM. I didn’t take Total T and SHBG for this bloodwork, but I took one from a year ago. Last year my total T was 550 eith free T on the lower end of the range. Based on this range and let’s say the test result is accurate, is my free T considered low for my age?

I tried calculating it by (17-9.2)/(34.6-9.2) times 100=30.7% which I believe it placed me on the lower 30% percentile, which I believe is low for my case and age. Is this correct?

This bloodwork was taken around a month ago. The bloodwork was taken 3.5 to 4 weeks after I tried using toremifene to ‘restart’ my HPTA, which i suspected skewed the result a little upwards.

You have higher SHBG and at your age, I would not be jumping the gun unless your FT is truly low/sub-par.

Why do you keep getting the wrong testing method done for FT?

To truly know where your FT level sits you should be getting Equilibrium Dialysis or Ultrafiltration.

The bloodwork from a month ago uses Dialysis method. The bloodwork from a year ago isnot specified so it might dialysis as well, since it was done at the same country.
The last free T bloodwork is the one that I am sure that uses the ELISA method

That is the only one I would rely on and your FT is just below the mean (mid-range).

To be honest, it is always best to test twice and within a few weeks in a fasted state between the hours of 8-10 am and I would go first thing in the morning 7-8 am.

Peak T levels would be between 6-8 am.

With the lab result, is my free T considered low for my age? Especially with the high SHBG and low LH

Depends on what test you are looking at as they are different assays let alone reference ranges and the only one I would rely on is the FT Equilibrium Dialysis.

Again when testing FT you should be using the most accurate assays such as the gold standard Equilibrium Dialysis or Ultrafiltration (next best).

Always best to use the same lab and the same assay (most accurate) for blood work so you can compare the results.


The first 2 tests your FT is below the mean (mid-range) and far from optimal.

The most recent test your FT is dismal and just above the bottom end (low).

The test does not show you are low. However, free T tests in Europe are notoriously bad and can be used only to detect increase/decrease not the actual value.

If you believe increasing free T will solve your problems, simply take Arimidex 0.5mg for a few consecutive days and repeat the same test. It should substantially increase your free T and give you a boost in sexuality. This will be a preview of TRT. It is unlikely to address anything else - it won't make you more muscular, more masculine, or more confident.

Testosterone is not a panacea and body builders actually abuse it several times outside of normal levels together with other anabolic steriods to get that muscular/masculine and the popular 'roids rage' is not actually confidence. Regular TRT doses do not have such effects.

The most recent one is these two,the 17 is the most recent one. While the 72.3 is taken a month ago.

Is this considered on the low end for my age?

I dont think this is right at all, taking arimedex will only crash my E while on TRT you should not aim to crash your E.
Within the range and the bloodwork that I showed you the (17 and 72.3 free T) is it considered on the lower end for my age?
