Frequently asked questions
Where should I start if I'm brand new to TRT?
The low-T quiz for symptoms, then the bloodwork guide so you know what to actually test. From there, a conversation with a provider.
What does "dialed in" mean on TRT?
Your dose, your labs, and how you feel are all lined up and stable. More in what "dialed in" actually means.
Do I need an aromatase inhibitor with TRT?
Almost certainly not. The real-world number is around 2.6% of men prescribed testosterone. Full context: do you actually need an AI.
Will TRT affect my fertility?
Testosterone-only shuts down sperm production. If fertility matters, running hCG alongside from the start is the standard move. See hCG on TRT and coming off TRT.
