Phentermine is one of the most popular weight loss drugs in the world. It has been proven effective for short-term weight loss when used alongside a reduced-calorie diet and exercise.

How Does Phentermine Work?

Phentermine belongs to a class of drugs called “anorectics,” also known as appetite suppressants. Taking phentermine helps suppress your appetite, thereby limiting how many calories you eat. Over time, this can lead to weight loss.

Phentermine remain acts by increasing neurotransmitter levels in your brain. Neurotransmitters are your body’s chemical messengers and include norepinephrine, serotonin, and dopamine. When your levels of these three chemicals increase, your feeling of hunger decreases.

*Several clinical studies have proven that phentermine can boost fat loss. The expected average weight loss with phentermine use is 5% of your initial body weight. Yet, over 12 weeks, it can be as high as 10%. This equates to a weight loss of 10–20 pounds) for a 200 pound person.
