    Lab results don't reflect increased dose

    Thanks. Keep in mind that my Adex dose changed from 0.5mg 2x weekly to 0.25mg 2x weekly at the same time my T dose changed from 120-140. I expected my E2 to increase with the change. I'm planning to pull SHBG next time I get blood work.

    Lab results don't reflect increased dose

    My doctor is my PCP. He's not up to speed with the latest protocols, but has a number of patients that he treats. He's open to discussion and learning and has even done research and spoken with colleagues in an effort to help me. I'm happy with the progress so far.

    Lab results don't reflect increased dose

    Thanks. I'll have to get it tested, but sounds like low SHBG may be a possibility. My E2 rose and I started experiencing symptoms several months after starting TRT, hence the AI. More frequent injections wouldn't bother me if I did need to go that route. In fact, I suggested my current 3.5 day...

    Lab results don't reflect increased dose

    My last test was 4 weeks after the dose change. I'm injecting every 3.5 days - Monday evening/Friday morning. All blood tests thus far have been done at the same time Monday afternoon, just prior to my injection. Remarkable improvement compared to prior to starting TRT. Still a small amount of...

    Lab results don't reflect increased dose

    Unfortunately SHBG was never tested. At 100 mg/week, Total T was 576, so I expect SHBG may be low. E2 is the sensitive assay.

    Lab results don't reflect increased dose

    My doctor recently upped my dose based on lab results, but total and free T don't seem to reflect the change. Previous dose 120 mg/ week (split 2x 60): Total T 762 ng/dL, Free T 21.2 pg/mL, E2 20.2 pg/ mL Upped dose to 140 mg/ week (split 2x 70). Retest 4 weeks later: Total T 780 ng/dL, Free T...

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.
