    If you are feeling great, how often do you pull labs?

    Twice a year - once with Endo checkup, once with physical. But my docs are cool if I wanted another test here and there. We have a good relationship. How I "feel" is a small part of my reasons for testing - I felt "fine" while I was developing gynocomastia over many years of poor protocol and...

    Peak vs Trough Levels?

    I am. At most 10% variation over a week. I inject 120 and get in the 800's midweek. I trim a bit of the E2 conversion by taking a tiny amount of AI 24 hours after injection. Have not felt the need for more frequent injections. But I suppose people process T differently as they do E2.

    For me - I see about less than 10% reduction from mid cycle to end cycle. However I will admit I have only tested maybe twice at end cycle. I almost always test at mid cycle but have tested closer to peak as well. I also understand natural full generators of T (guys who dont need TRT) to have...

I have had troubles explaining to doctor and labs what sensitive E2 test is - its not common. I have been tracking it for a while now. It...

    My TRT labs

    Hi, Generally no major complaints with my hormone (feeling) these days. In the last year or so I upped my T injection from 100 to 120 mg. My last ESTRADIOL (ICMA) test was 38 pg/mL. I am controlling E2 with compounded very small dose arimidex. Tests very of course due to me trying to time...

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.
