Testosterone gel and testosterone cream may sound interchangeable—but does the formulation actually change how much testosterone gets into your bloodstream?
I recently came across research that made me take a much closer look at this question, and the difference surprised me.
In this video, I compare research looking at topical testosterone in postmenopausal women and explore why the same milligram dose does not necessarily produce the same blood testosterone level when delivered in different formulations.
We’ll talk about what the studies show about absorption and serum testosterone levels, why blood tests don’t always tell the whole story, and how factors including SHBG and protein binding, androgen receptor variation, and intracellular testosterone production can complicate the picture.
I also take a closer look at the Global Consensus recommendations for testosterone therapy in women—and an important limitation: much of the evidence behind current recommendations comes from studies using a low-dose testosterone patch that is not currently available.
I’m also currently participating in a large testosterone study in collaboration with Baylor College of Medicine. The study is still underway, so we don’t yet have final results, but we are already seeing preliminary data that adds another interesting piece to this conversation. I share some of those early numbers in the video and explain why they caught my attention.
The bigger point? Testosterone therapy in women is nuanced. Dose matters. Formulation matters. Blood levels matter. But so does the individual woman and how she responds.
This is something I just learned more about, and I couldn’t wait to share it with you.Studies discussed:
