Kamagra Oral Jelly is a popular and effective treatment for erectile dysfunction (ED). It contains sildenafil citrate, which is the same active ingredient found in Viagra. The main difference is that Kamagra Oral Jelly comes in a gel form, making it easier to swallow for those who have difficulty with tablets. It's designed to be taken orally and typically starts working within 15-30 minutes, providing relief from ED for up to 4-6 hours.
