Is Zenegra effective?

If Zenegra genuinely contains the correct dose of its intended active ingredient, sildenafil citrate (which is the same stuff in Viagra), then yes, it should be effective for treating erectile dysfunction in men. Sildenafil works by increasing blood flow to the penis when a man is sexually aroused, helping him achieve and sustain an erection. However, a big "if" hangs over many such branded generics like Zenegra: they are often sourced from unregulated channels. This means there's no solid guarantee of the actual dosage, purity, or even if it contains sildenafil at all. So, while the drug itself (sildenafil) is proven effective, the effectiveness of a specific unregulated product like Zenegra can be a gamble, ranging from working as expected to being completely ineffective or, worse, causing unexpected side effects due to incorrect dosage or contaminants.
