Disposition and Metabolism of Finasteride in Dogs

Finasteride is metabolized in the liver and excreted through urine and feces. Users humorously discuss its excretion, with one joking about it being expelled through ejaculation.

Finasteride is not linked to a 60% risk of persistent sexual dysfunction; this figure applies only to those already experiencing sexual issues. Most users do not have side effects, and the study's methodology is criticized for selection bias.

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.

Dutasteride is more effective than finasteride, has neuroprotective benefits, and may prevent acne. Despite initial concerns about metabolic effects, further research suggests it is safe for most users, especially if not hypogonadal.

The conversation discusses the potential benefits of creating a hydrophobic version of finasteride to reduce systemic side effects while maintaining scalp health. It compares this idea to fluridil, which is designed to be hydrophobic and has less systemic absorption.

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.
