Anastrozole / Exemestane (Aromatase Inhibitors) vs Testosterone (TRT)

Both are used for sexual health. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.

Anastrozole / Exemestane (Aromatase Inhibitors)Testosterone (TRT)
Human evidence★★★★☆★★★★★
Legal statusPrescription, Off-LabelControlled, Prescription
How it worksInhibit aromatase (CYP19A1), the enzyme converting testosterone to estradiol. Anastrozole is reversible; exemestane is a suicide (irreversible) inhibitor.Binds the cytoplasmic androgen receptor (AR); the hormone-receptor complex translocates to the nucleus and binds androgen response elements (AREs) on DNA, switching on genes for muscle protein synthesis, erythropoiesis, and bone density.…
In plain EnglishHigh testosterone partly converts to estrogen, which can cause bloating and gyno. These drugs block that conversion. Easy to overdo — crashing estrogen wrecks mood, joints, and libido.Testosterone slots into a docking station (the androgen receptor) inside your cells, which then walks to the cell's DNA and switches on the "build muscle, make blood, strengthen bone" genes. TRT restores a normal level in men who are…
Bottom lineUse only if estradiol is genuinely high; low estrogen is as bad as high.Transformative for confirmed low-T; a different risk equation for enhancement in normal men.
