What good TRT monitoring actually looks like
Labs, cadence, and the numbers your provider should be watching beyond total testosterone.
Starting testosterone is the easy part. Monitoring it correctly is what separates a well-managed protocol from one that quietly drifts into trouble.
The baseline panel
Before the first dose: total and free testosterone, SHBG, estradiol (sensitive assay), LH, FSH, CBC, CMP, PSA (if over 40), and a lipid panel. This isn't box-checking — it's the reference point every future draw compares against.
The cadence
Recheck at week 6, again at week 12, then every 6 months once stable. Hematocrit is the number that most often forces a protocol change; anything above 54% warrants a dose reduction or a therapeutic phlebotomy.
Estradiol, honestly
Most men on physiologic TRT do not need an aromatase inhibitor. Reflexively prescribing anastrozole crashes estradiol and creates its own set of problems — joint pain, low libido, poor lipids. Treat symptoms and trends, not a single number in isolation.
What we're really watching
Symptom resolution, hematocrit, PSA velocity, and lipids. A total testosterone of 900 with a hematocrit of 56 and a rising PSA is not a win — it's a protocol that needs adjustment.
