      I was recently prescribed Finasteride (5-AR inhibitor) to help with my thinning hair. I plan on taking either 1 mg or .5 mg daily. I know gynecomastia will be an issue so I also plan on taking the aromatase inhibitor Letrozole. I want to keep my estrogen low by inhibiting the aromatase enzyme and keep my dihydrotestosterone low by inhibiting the 5-alpha reductase enzyme. I know there are side effects associated with completely eliminating estrogen or DHT. My question is, how much Letrozole should I be taking to offset the increase in estrogen due to the inhibition of the 5-alpha reductase enzyme?
