Adipex is a prescription medication that is used to treat obesity. It is a stimulant that helps to suppress appetite and increase energy levels. Adipex is available in both oral and extended-release forms. The oral form is taken once daily, while the extended-release form is taken once every 24 hours. Adipex is typically prescribed for short-term use, and it should not be taken for more than 12 weeks. Adipex is a controlled substance, and it is illegal to buy or sell it without a prescription. However, there are many online pharmacies that sell Adipex without a prescription. These pharmacies are often located in countries where prescription drugs are not regulated as strictly as they are in the United States.
