How does phentermine work?

Phentermine increases energy and reduces appetite by stimulating the central nervous system to release norepinephrine from the hypothalamus.

This appetite suppressant drug is most often prescribed for short-term use from 1 to 3 months at a time, with close monitoring by the prescribing physician to ensure safety and success.

How can I get phentermine?

Phentermine is a schedule IV prescription drug and is only available via a doctor’s prescription after a face-to-face consultation and bloodwork.

These hurdles are necessary to ensure the safety of patients. Phentermine has numerous side effects ranging from mild to serious, and some people have pre-existing conditions that make it unsafe for them to use phentermine or similar drugs.
