Your HPTA is shut-down while on TRT so conventional / natural means to boost testosterone like Ashwaganda will not work. However you may get the other supposed benefits of Ashwaganda like reduced cortisol, feelings of anxiety & stress, and energy boost.
If you want to boost testosterone further you have a couple options:
- Increase your weekly dose,
- Decrease SHBG.
- Decrease conversion into Estrogen.
You could start supplementing with Boron 9mg/d. Some people respond well and see a remarkable consistent decrease in SHBG, some don’t.
To reduce aromatase expression I would first suggest losing bodyfat, you want to be around 12-15% bodyfat ideally.
Lastly you can support the liver to help increase the clearance of Estrogen from the body. This may also help decrease SHBG, it’s common to see SHBG elevated when liver healthy is impaired. I’m personally trying NAC to improve liver health - there is some clinical data showing Testosterone & Fertility improved after NAC supplementation.
Hope it helps and good luck.
