Phentermine is a prescription weight loss drug that has been widely used for decades. It is an appetite suppressant that works by increasing the levels of certain neurotransmitters in the brain, which leads to decreased hunger and increased energy.
In recent years, there has been a growing trend of people buying phentermine online. While there are some legitimate online pharmacies that sell phentermine, there are also many dangerous and fraudulent websites that sell counterfeit or contaminated products.
