A note from Dr. Green

“Both Semaglutide and Tirzepatide are popular amongst Willow patients who have reported seeing weight loss. Tirzepatide tends to lead to greater weight loss for many patients, while Semaglutide remains a strong, reliable option. There's no single "better" choice between Semaglutide and Tirzepatide. What matters is what fits your body, your goals, and your lifestyle. Our doctors will walk you through the differences and help you land on the right option.”

Semaglutide

Tirzepatide

Overview

GLP-1 receptor agonist

Mimics a natural hormone released after eating that helps regulate appetite, increase feelings of fullness, and support healthy blood sugar levels.

GLP-1 + GIP receptor agonist

Targets two metabolic hormone receptors (GLP-1 and GIP) that help regulate appetite, support fullness, and improve blood sugar control.

How do they work?

  • Target hormones that regulate hunger and fullness
  • Activate signals in the brain that control appetite
  • Slow how quickly food leaves the stomach
  • Help regulate how the body responds to food
  • Work across key pathways involved in metabolism
  • Help reduce food noise and cravings

What patients say

4.9/5 (2200 + 5 star reviews)
"I received a quick response from all involved. Since I am on maintenance and not starting from the beginning of my weight loss journey, I was surprised my inquiry was welcomed. Several other web sites did not want to even talk about my goals as they were only willing to prescribe for starting BMI and not look at maintaining that weight lost!"
Linda K.
"I was 100% satisfied with the experience, then Willow managed to improve the experience even more when a non-weight loss related issue came up suddenly. I could not have asked for better response time & actions taken. I'm so happy I chose Willow given all of the providers out there."
Susan K.
"Nothing but a good experience with Willow. I'm almost to my goal weight. I've lost 25 lbs. From the doctors to the staff everyone is great and very responsive. I've referred a friend and she is having a great experience too. Highly recommended!"
