Erectalis is a 100 mg tablet containing the active ingredient sildenafil citrate. This potent component is effective only in the presence of sexual stimulation. As a PDE5 inhibitor, it relaxes the penile arteries and enhances blood flow to the penile region, resulting in a strong and long-lasting erection. Men can maintain firmness for up to 4 hours after ingestion, allowing for multiple sessions of pleasurable intercourse.
