Glossary Oral Testosterone

hormone therapy in pill form for low testosterone levels

Oral Testosterone, also known as Testosterone Pills or Testosterone Tablets, refers to a form of testosterone replacement therapy where the hormone is administered in pill form. This method is used to treat conditions caused by low testosterone levels, such as hypogonadism. While convenient, oral testosterone can have significant liver metabolism, which may lead to liver toxicity, making other forms like injections or transdermal patches often preferred.

research Steady-state pharmacokinetics of oral testosterone undecanoate with concomitant inhibition of 5α-reductase by finasteride

10 citations , October 2010 in “International Journal of Andrology”

In this study, co-administration of finasteride with oral testosterone undecanoate in young men with induced hypogonadism had no significant effect on serum testosterone or dihydrotestosterone levels, likely due to TU's unique absorption route.

community High testosterone on 4 months dut, rapidly receding but no actually shed

in Finasteride/Dutasteride 21 upvotes 1 year ago

The user added 0.5mg dutasteride to their regimen of topical finasteride and minoxidil but experienced rapid hairline recession despite reduced hair fall. Suggestions included increasing the dutasteride dosage to 1mg daily to better suppress DHT and potentially adding oral minoxidil.

community Oral fin -> topical, shedding like hell

in Finasteride/Dutasteride 19 upvotes 5 months ago

The user experienced severe side effects from oral finasteride, including sexual dysfunction and mental health issues, and switched to topical finasteride, which led to significant hair shedding. They are considering other treatments like RU58841 or topical dutasteride and are advised to check testosterone levels and address potential underlying health issues.

community DHT nearly doubled after switching to oral Fin

5 upvotes 6 months ago

The user switched from topical Minoxidil and Finasteride to oral Finasteride and reduced testosterone, expecting to lower DHT, but instead, DHT increased and hair loss worsened. The user is seeking advice on whether to return to the previous topical treatment or if others have experienced similar issues with oral Finasteride while on TRT.

community Very high free testosterone on dut…

learn Finasteride

Popular 5-alpha reductase inhibitor that lowers DHT, taken as a pill or used topically

Topical or oral? Choosing between pills and lotions according to your case. In studies, topical finasteride gave much lower blood levels of the drug than tablets but still lowered blood DHT, and whether it causes fewer side effects has not been established. There is no FDA-approved topical finasteride, and the FDA warned about compounded versions in April 2025.

learn Dutasteride

5-alpha reductase inhibitor that blocks both enzyme types, a stronger DHT blocker than finasteride

learn Bicalutamide

Nonsteroidal anti-androgen, originally a prostate cancer drug

learn Spironolactone

Blood-pressure and diuretic drug with anti-androgen effects

learn Cyproterone

a synthetic anti-androgen and weak progestogen that inhibits DHT binding to androgen receptor

learn Vitis vinifera

Is Vitis vinifera more effective in oral supplements or topical products? Neither oral nor topical grape extract has been tested for hair loss in a human trial; topical use has only a theoretical, mouse-based rationale.

learn Metformin

Is metformin used topically for hair loss, or only as an oral tablet? Approved metformin products are oral tablets only; there is no approved topical metformin for hair loss. Published human reports of topical use are a handful of uncontrolled, pharmacy-compounded case reports in scarring alopecia, and the most-cited clinical series actually used the oral drug.

learn Sulforaphane

Is sulforaphane used in oral supplements or topical hair treatments? Sulforaphane is primarily used in oral supplements, not topical hair treatments.

learn white tea

Is white tea more effective in topical hair products or as an oral supplement for hair growth? Neither topical nor oral white tea has any human clinical trial behind it for hair growth. Topical use has a more direct mechanistic rationale, but the only verifiable studies are a cell-culture EGCG experiment and a pharmacokinetic study with no hair outcomes.
