Synthesis of 5,6,6-[2H3]Finasteride and Quantitative Determination of Finasteride in Human Plasma at Picogram Level by an Isotope-Dilution Mass Spectrometric Method

Finasteride and Nizoral shampoo with Ketoconazole are used for hair loss treatment. Liquid Chromatography–Mass Spectrometry (LC-MS) is recommended over Enzyme-Linked Immunosorbent Assay (ELISA) for more accurate DHT testing.

The user had high DHT levels after 8 months on dutasteride, questioning the drug's authenticity. They got dutasteride from a legitimate source and will update on progress.

The user reported high testosterone and estradiol levels within range, but unexpectedly high DHT levels after using finasteride and dutasteride for hair loss. Another person suggested the dutasteride might be fake or a bad batch and recommended using the branded Avodart.

The user has been using dutasteride and finasteride but still experiences hair loss and high DHT levels. They plan to try topical finasteride and RU58841 while continuing dutasteride to see if topicals are more effective.

The user discovered their previous hair loss medication was counterfeit and switched to Propecia, which significantly lowered their DHT levels. They plan to continue using Propecia and add oral Minoxidil to their routine for better results.

Dutasteride effectively reduces DHT levels and significantly increases testosterone levels. Users are cautious about adding oral minoxidil due to potential heart issues and are considering dosage adjustments with medical guidance.
