Kamagra 100 is sold as a tablet that you can take to improve your libido and erectile dysfunction, but it is not guaranteed to be safe for you. Kamagra is manufactured in India and is not approved for use in the EU. It is illegal to buy or sell Kamagra in the UK. Some men buy Kamagra online because they believe it is a cheaper alternative to approved erectile dysfunction treatments like Viagra. According to the manufacturer, Ajanta Pharma, Kamagra contains 100 mg of sildenafil citrate. Sildenafil is a drug used to treat erectile dysfunction and usually requires a consultation with a doctor and a prescription to make sure it is safe for you.
