The official website of the Food and Drug Administration clearly shows that there are currently 49 domestically produced tadalafil products approved for marketing. The most commonly seen products on the market are Ai, Cialis, and Caspian. These. If you want to be economical, you can choose domestic brands. If you are in a good economic situation, you can also choose imported brands. Their medicinal effects are similar.

I would also like to remind everyone to check the drug manufacturer clearly, and then go to the drug supervision official website to check whether the manufacturer is regular and qualified, so as to ensure that the medicine you buy is genuine.
