One common drug used to treat erectile dysfunction is Kamagra 100mg.  Its legality on the internet differs by nation.  Purchasing it without a legitimate prescription is prohibited in some areas since it is regarded as a prescription-only medication.  Although Kamagra 100 is sold by many internet pharmacies, not all of them are reliable or licensed. 

 It might be dangerous to buy from unreliable sites since dangerous or fake goods might be offered.  Always verify local laws and use authorized online pharmacies to keep safe and stay within the law.  It is strongly advised to seek medical advice before to use for both safety and efficacy.
