Tadalafil is a popular drug used to treat erectile dysfunction. It has been found to be more effective than brands such as Viagra, so it has been gaining popularity. This drug can be purchased from countries such as India and China, where it is more affordable. However, there are many factors that need to be considered before you purchase this drug from an overseas pharmacy. For example, the quality of the medication may not be what you expect or what you need for your condition. Additionally, the lack of regulation in some countries may leave you with a counterfeit product. Here, you do not need to get prescribed before purchasing cialis online.
