GLP-1 pen · once weekly
Your weight loss breakthrough is here.
MERESA (semaglutide injection) is designed to make weekly dosing feel less intimidating and more approachable.
A once-weekly GLP-1 pen, prescribed and monitored by licensed clinicians, for eligible patients.
Why Meresa
Weight loss designed around you.
Meresa is a GLP-1 injected once per week, working with your body's appetite signals and a structured plan from Fits clinicians.
How Meresa supports progress
GLP-1 medications like Meresa mimic hormones that help regulate appetite and blood sugar, allowing individuals to feel satiated and satisfied for longer periods of time when combined with changes in eating and activity.
With Fits, weekly Meresa injections are paired with clinician-guided dose adjustments, so your treatment can be slowed down or stepped up based on how you feel and how your body responds over time.
Meresa is meant to be one part of a broader plan: nutrition habits, movement you can stick with, sleep, and ongoing check-ins that help keep weight loss sustainable rather than a short-term sprint.
Meresa is taken once a week on the same day, with dose changes guided by your Fits clinician over time.
