Other weight loss places may make promises and guarantees, but instead of gimmicks we prefer to let the results speak for themselves. Results are dependent on individuals, so come and find out what you can achieve. On phentermine a lot of the weight loss happens toward the beginning of treatment.

With this treatment you can start to lose weight fast. It is common to lose 7-10 pounds in the first two weeks.

This treatment is a particularly good fit for you if you are budget sensitive, have never been on stimulant medication before (no ADHD medication etc.), and/or need super fast results.
You can not be treated with phentermine if you:

  • Already on another stimulant medication (like ADHD medications)
  • History of stroke, heart attack, heart disease or uncontrolled high blood pressure (unless cleared by cardiologist)
  • Chronic kidney disease (unless cleared by nephrologist)
  • Nursing, Pregnant, or trying to get pregnant

You can still use phentermine if you have any other medical conditions not listed above.

  • Lots of energy
  • Dry mouth
  • Insomnia
  • Constipation
  • Moments of feeling hot and sweaty
  • Irritability
If you have been on phentermine (or any stimulant medication like for ADHD) you may have built up a tolerance to the effects of the medication. We recommend you consider trying semaglutide.
We do not process any insurance. Unfortunately, most insurance companies refuse to cover medical weight loss, but we are happy to provide invoices for reimbursement if your insurance does. Some patients are able to get reimbursed for the visit.
