Testosterone · Bloodwork · TRT · Longevity


My GP told me my testosterone was "normal." It was 8.4 nmol/L. That is normal the way a one-star review is technically still a review. I felt exhausted, foggy, and about as motivated as a damp flannel. So I did what any reasonable person does: I spent six months reading endocrinology papers at midnight and got progressively worse at dinner parties.

Turns out my levels were low, my SHBG was high, and my GP had not checked either of those things.

I built this site so you do not have to become a hobbyist endocrinologist to get answers. I have now had my testosterone tested 11 times in four years. My wife describes this as "a lot." She is being generous.

Amy keeps me honest on sleep. She knows that research better than I ever will. Edith disagrees with me on nutrition timing approximately twice a week and is, irritatingly, usually right. Marcus made me buy a foam roller I did not think I needed. My hamstrings have never forgiven me for doubting him.

"Has had his testosterone tested 11 times in 4 years. Keeps a spreadsheet."


Seb covers: testosterone, bloodwork interpretation, TRT in the UK, longevity protocols, and the kind of detail most men's health content skips because it assumes you will lose interest.
