Black Viagra 200mg is highly effective for treating erectile dysfunction (ED) in men. It contains Sildenafil Citrate, the same active ingredient in Viagra, which enhances blood flow to the penis, helping to achieve and maintain an erection during sexual activity. Cenforce 200mg is particularly effective for men with moderate to severe ED. It should be taken about 30 to 60 minutes before sexual activity, with effects lasting up to 4 hours. While it’s effective, it’s essential to use it under medical supervision to ensure safety and manage any potential side effects, such as headaches or dizziness.
