My average total testosterone is an ideal 704∓44 ng/dL.
- I achieved this naturally
- my LH and FSH levels are evidence I am not on TRT
- data is from seven measurements over the past year
I achieved this by:
prioritizing sleep and exercise
nutrition powered by Blueprint
avoiding endocrine disruptors (such as microplastics, leachables, and PFAS)
I do not use TRT or any form of HRT. My LH (8.7∓1.25 ng/dL) and FSH (7.4∓2.0 ng/dL), both measured three times in the last year, are consistently in the mid-high normal range with minimal fluctuations, further indicating natural hormone production.
My free testosterone, the active form crucial for sexual drive and anabolic function, consistently registers in the upper reference range (94∓6 pg/ml) based on three measurements over the past year. This is despite a slight elevation in SHBG (64.6, ∓2.7 nmol/L), measured seven times in the same period.
The slightly increased SHBG is due to my high exercise levels, partial calorie restriction, and somewhat elevated thyroid hormone levels due to medication. I am adjusting my regimen to bring my thyroid hormone levels back to the optimal mid-normal range.
