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.
