Thanks madman. I live in BC. The reasons I started with daily are because my hematocrit had been at the top of the range (50-51) for the past couple of years without any TRT. Also, I had a lowish SHBG reading before starting (23.4nmol/L). I had quite a poor sleep before that reading so this may have affected my levels. Also, I was just under the impression that daily was somehow better, it is just over the past few weeks that I am coming to see that this is not necessarily the case.


Another reason I went for daily is because I tried TRT back in 2017 and the doc told me to do a weekly shot of 100ml. I did the first shot and my prostate felt very swollen and painful for a few days. This gave me pause because I have friends who suffer from long term prostatitis so I decided to wait for a few years until I was in my 50s to try TRT again. At that point my libido was still decent so it wasn’t a priority for me. I thought maybe a daily would avoid this prostate swelling from happening again.


These labs are from Lifelabs. I live on an island which has a Dynacare lab but they won’t do any free T etc if my total T is in range, even if I am paying. So I have to travel off island to Lifelabs. Maybe I will try the local lab again and see if they can do the sensitive Estradiol test.


Maybe the estradiol test was off somehow. I am not holding any water and my mood is pretty good. Sensitive nipples seem common when starting TRT and there is no itching or other symptoms.


Here are the reference ranges:

Estradiol 207 Ref Range <162 pmol/L

Testosterone 30.2 Ref Range 8.4-28.8 nmol/L

Testosterone Free Calculated 678 Ref Range 115-577pmol/L Method of Vermeulen

Testosterone Bioavailable Calculated 15.9 Ref Range 2.7-13.5nmol/L Method of Vermeulen

Sex Hormone Binding Globulin 35.4 Ref Range 19.0-76.0nmol/L

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
