Androgen Biosynthesis and Gene Defects

A user is curious why their DHT levels are not higher despite using 400mg of testosterone without finasteride, and wonders if zinc or GHK-Cu injections could be influencing this. Another user suggests that more testosterone typically leads to more DHT, but the user might be fortunate not to exceed normal DHT levels.

Dutasteride may affect testosterone levels, leading to high ferritin and iron levels, which can cause hair loss. High ferritin might be linked to past heavy drinking or hemochromatosis.

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.

A user on Finasteride for 7-8 years reported unexpectedly high testosterone levels despite expecting lower levels due to age, with discussions on the impact of SHBG and suggestions to use boron to lower SHBG. Another user noted that Dutasteride significantly increased their testosterone and free testosterone levels.

The user experienced hair shedding after starting testosterone replacement therapy (TRT) and is considering using DHT blockers like finasteride or dutasteride to address potential DHT-related hair loss. Low ferritin levels due to frequent blood donations may also contribute to hair issues, and the user is working on stabilizing iron levels.

Finasteride and its effects on hair loss, with discussions on the role of estradiol and estrogen. Users debate whether increased estrogen from DHT blockers contributes to hair regrowth, with concerns about potential side effects like chemical castration.
