An Innovative Reverse-Phase High-Performance Liquid Chromatography Technique for Measuring Finasteride and Tadalafil in Raw Materials and Pharmaceutical Products with Stability Indication

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 is about gathering serum DHT data from individuals taking dutasteride to investigate its efficacy, especially in cases with unexpectedly low DHT reduction. The aim is to explore potential genetic factors affecting drug metabolism.
