Determination of Finasteride in Human Plasma by Liquid-Liquid Extraction and High-Performance Liquid Chromatography

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.

The user is taking finasteride 1mg from Blink pharmacy, sourced from Ascend Laboratories, with no noticeable side effects after 5 months. They also use Kirkland foam minoxidil, micro needling, and various supplements for hair treatment.

Topical finasteride in a liposomal formulation reduces systemic absorption compared to ethanol solutions. The user is seeking sources for such products, noting that popular options like morr-f are not liposomal.

A user discusses using Alpecin Caffeine Liquid for scalp health and considers dissolving finasteride tablets into it for a DIY topical treatment. They inquire about potential absorption issues with this method.

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

A 26-year-old has been using finasteride for over two years, initially at 1.25mg daily and later at 5mg weekly, resulting in stable hair condition with some regrowth and minimal side effects. The user reports high libido and a protein and vegetable-heavy diet, with initial watery semen as the only side effect.
