When traveling to Germany, do I need to declare estrogen-regulating drugs?

According to German customs regulations, if you are carrying prescription drugs or other drugs that require hormone regulation, you need to declare and obtain relevant permission. According to EU regulations, if you are carrying psychotropic drugs or narcotic drugs that belong to the third category, you need to present a doctor's prescription and a letter from the doctor when clearing customs to explain that you need to bring these drugs into the country. These regulations may vary depending on individual circumstances and specific medications, and I recommend that you check with the German Embassy or Consulate before departure for the most up-to-date access regulations and requirements.
