After taking the first dose of Cenforce 100, most users can expect to experience improved erectile function within 30 to 60 minutes, provided there is sexual stimulation. The effects can last for up to 4–6 hours. Many men report stronger and longer-lasting erections, increased confidence, and improved sexual performance. However, results may vary based on factors like age, overall health, and whether the drug is taken on an empty stomach. Some users may also experience mild side effects such as headache, flushing, or nasal congestion. It’s important to follow dosage instructions and consult a doctor if unsure.
