Episode notes
Optimize Foundations Before TRT
- Before trying testosterone replacement, optimize basics like magnesium, boron, zinc, creatine, fish oil, vitamin D, sleep, and leg strength training.
- Re-test testosterone after 6–8 weeks and consult a precision/functional medicine doctor for tailored therapy.
Toxins, Fat, And Hormone Function
- Environmental toxins and microplastics can act like xenoestrogens and blunt testosterone action even if levels look normal.
- Body fat stores toxins, so rapid fat loss can temporarily mobilize harmful compounds and cause symptoms.
Prefer Steady Dosing To Mimic Physiology
- If using testosterone, avoid pellets or large infrequent injections that create unphysiological surges; consider creams or oral short-acting options for steadier profiles.
- If fertility matters, add clomid, enclomiphene, or hCG rather than full suppression.
