Malegra because you can't reliably know what is actually in the tablet or how much of it is present. Genuine Malegra products are intended to contain sildenafil, but counterfeit tablets can have: Too much or too little sildenafil, increasing the risk of side effects or treatment failure. Different or undeclared drugs, potentially causing dangerous interactions. Contaminants or incorrect ingredients from poor manufacturing. Unreliable dosing, making accidental overdose more likely. No reliable guarantee of quality, storage, or manufacturing standards. This matters particularly because sildenafil can cause a significant drop in blood pressure when combined with nitrates, and excessive doses can increase adverse effects such as severe headache, dizziness, vision disturbances, or prolonged erection. If you already have a pack of Malegra and want to know whether it appears legitimate, you can tell me the manufacturer, strength, and what is printed on the packaging (or upload a photo), and I can help you check the information.
