Effect of Testosterone Supplementation With and Without a Dual 5α-Reductase Inhibitor on Fat-Free Mass in Men with Suppressed Testosterone Production: A Randomized Controlled Trial

A 30-year-old man experienced significant hair regrowth and improved libido after using finasteride and dutasteride for androgenetic alopecia, with no adverse effects. He plans to reduce dutasteride dosage when trying to conceive and has been using topical minoxidil since 2015.

Dutasteride can significantly increase testosterone levels, sometimes more than finasteride, which may be counterproductive for some users. Users report varying experiences with testosterone levels and hair loss management while using these treatments.

A bodybuilder uses 1400mg testosterone weekly, 400mg equipoise, and GH, with 0.5mg dutasteride daily to stabilize hair loss and manage DHT levels. The user reports no side effects from dutasteride and finds it effective, while also discussing costs and effectiveness of other treatments like RU58841 and minoxidil.

Dutasteride is recommended for men on testosterone replacement therapy (TRT) with DHT-sensitive hair, as it does not interfere with TRT's anabolic effects and may improve libido and aging male symptoms. Users report varying experiences with libido when switching from finasteride to dutasteride, with some noticing improvements and others experiencing fluctuations.

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.

A user experienced hair thinning after using tamoxifen and bupropion and is now using topical dutasteride, alfatradiol, melatonin, adenosine, and specific shampoos for improvement. They are considering using steroids and are seeking advice on whether combining oral dutasteride with TRT/PEDs would affect hair health, with mixed opinions on the impact of testosterone and DHT on hair loss.
