Mechanism
How Sildenafil works
Sildenafil inhibits PDE5, increasing cGMP so blood vessels in erectile tissue relax and fill during arousal. Take on an empty stomach for fastest onset — high-fat meals delay absorption.
Your protocol
Taken orally as directed by your provider. Follow the exact regimen on your prescription label and the materials shipped with your order. Your provider personalizes the dose and schedule to your goals, then adjusts it over time based on your response.

The Science
What Sildenafil is, where the evidence stands, and how your clinician applies it.
Sildenafil is the original PDE5 inhibitor — the generic form of Viagra® — and remains the most prescribed erectile dysfunction medication worldwide. It has a rapid onset of 30 to 60 minutes and a 4 to 6 hour window, making it the standard choice for as-needed use with decades of safety data behind it.
Clinical oversight
Sildenafil is prescribed only after a licensed clinician reviews your medical history, current medications, and any relevant labs. Side effects and contraindications are reviewed with you before treatment begins, and your provider monitors your response throughout.
