Gender-affirming hormone therapy improves physical performance in trans men to the level of cisgender men, while in trans women, it increases fat mass and decreases muscle mass, with no advantage in physical performance after 2 years.
The document concludes that finasteride can reduce nandrolone detection in doping tests, suggesting frequent testing and setting metabolite level thresholds for detection.
Long term Finasteride users and whether or not they have noticed improvements after two years of use, with other treatments such as Minoxidil and dermarolling also discussed. Some replies suggest that improvement is possible even beyond the two year mark while others caution against believing studies backed by the Post-Finasteride Foundation.
Finasteride can cause sexual side effects in less than 2% of men, but these often disappear over time, even if the treatment continues. Some users report persistent side effects, while others experience no issues or only temporary ones.
Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
Hair loss treatments, specifically 5AR inhibitors, can impact neurosteroids and sexual health. The effects of topical fin/dut on tissue-specific DHT levels are unclear.
Minoxidil alone is often insufficient for treating hair loss because it doesn't address the DHT-related cause. Combining it with finasteride, a DHT blocker, is generally more effective.
