Validated LC-MS/MS Method for Simultaneous Quantification of Finasteride in Human Plasma

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.

A user is making a homemade topical finasteride solution by dissolving crushed finasteride tablets in ethanol and PG. They are unsure if the final solution maintains the intended concentration after filtering and are considering adding more ethanol to ensure accuracy.

The conversation discusses using very low dose topical finasteride to achieve specific serum DHT reduction percentages. It concludes that finasteride dosage increases linearly between 5-30% DHT reduction but requires exponential increases for reductions up to 70%.

User experienced good results with topical finasteride, noting reduced DHT and increased testosterone. They plan to revert to a lower dosage after observing slight libido reduction.

Topical finasteride results in plasma levels 100 times lower than oral finasteride, potentially reducing systemic side effects. Users report similar efficacy with fewer side effects, suggesting a preference for topical application.

The user experienced a significant drop in libido and erectile issues after increasing their finasteride dosage, combining oral and topical treatments. They plan to take a break and resume using a lower concentration of topical finasteride to manage side effects.
