Proscar (Finasteride)

What is Proscar (Finasteride)?

Proscar is a tablet form of a compound called Finasteride. Finasteride blocks an enzyme. An enzyme is a protein that speeds up a chemical reaction.

The enzyme is called 5-alpha reductase. It normally turns testosterone into another hormone called DHT (dihydrotestosterone). Each tablet holds 5 mg of Finasteride.

What researchers study it for

• Enzyme blocking. Researchers study how Finasteride blocks the 5-alpha reductase enzyme.
• DHT levels. Studies measure how much it lowers DHT. Levels can drop by up to 70% in the blood and up to 90% in the prostate gland.
• Hair follicle tissue. Labs study how lower DHT levels affect hair follicle cells.
• Hormone balance. Researchers study the balance of testosterone and DHT. This is often studied alongside anabolic steroid research.
• Dosage patterns. Studies commonly use 5 mg once a day.

What you get

One bottle of 30 tablets. Each tablet holds 5 mg of Finasteride.

How to store it

Keep the tablets in a cool, dry place. Keep them out of direct light and out of reach of children.
