It is also important to note that Kamagra 100 is no longer available in the same dosage as Viagra. The best dose of Sildenafil and Viagra in the UK is 100mg tablets and there is a reason for this: top people think that 50mg should be enough and 100mg should be the most convenient, while 50mg is useless. Kamagra doses can exceed 100mg, causing practical dosing issues.
