Effects of Finasteride, a 5 Alpha-Reductase Inhibitor, on Circulating Androgens and Gonadotropin Secretion in Hirsute Women

Switching from finasteride to dutasteride may be more effective for hair regrowth due to dutasteride's stronger enzyme inhibition, but combining both drugs could enhance results. Some users report better outcomes with dutasteride, while others recommend a gradual transition to prevent potential hair loss.

Combining dutasteride and an aromatase inhibitor may increase testosterone levels significantly, potentially enhancing athletic performance but also posing health risks like elevated blood pressure and worsened cholesterol. The user is experimenting with dutasteride, anastrozole, minoxidil, and ketoconazole shampoo to manage hair loss and estradiol levels, while monitoring side effects and hormone levels.

Finasteride has no effect on the user's estradiol levels, and body fat may influence aromatization. The user is on testosterone replacement therapy and uses everyday injections to manage high RBC count, with plans to measure DHT, DHEA-S, and pregnenolone levels.

The user is considering resuming finasteride after a 6-month break and is debating the necessity of extensive blood work, including hormone and health markers, to establish a baseline. They are unsure if the tests are necessary since they experienced no side effects previously.

Exercise has minimal impact on hair loss, with weight lifting slightly increasing DHT and cardio potentially decreasing it. Finasteride and dutasteride are effective treatments for managing hair loss, even for those who exercise regularly.

RU58841, a potential hair loss treatment, was not commercialized due to marketability issues and lack of long-term safety data. Concerns about its formulation and delivery methods further complicate its use.
