Frequently asked questions

Is Calibrate cheaper than Willow?

Calibrate starts lower on semaglutide (Membership $199/mo (3-month commitment); medication via insurance, copays ≤$25/mo). Calibrate starts lower on tirzepatide (Membership $199/mo (3-month commitment); medication via insurance, copays ≤$25/mo). Higher doses can shift the picture, so confirm pricing at the dose you're likely to use long-term.

Which is better for semaglutide or tirzepatide, Calibrate or Willow?

Calibrate starts lower on both semaglutide and tirzepatide based on listed entry pricing. That said, the right pick is the program whose support model and formulation match what you actually need.

Are Calibrate and Willow compounded or brand-name?

Calibrate offers brand-name glp-1 paired with coaching. Willow offers compounded glp-1 (semaglutide) and glp-1/gip (tirzepatide), your choice of once-weekly injection or once-daily sublingual tablet; nad+ also offered. If you specifically want brand-name Wegovy or Zepbound, lean toward whichever explicitly supports brand access; if compounded is fine, both can typically meet that need.

Can I switch from Calibrate to Willow?

Yes, switching between Calibrate and Willow is straightforward in most states. You typically finish your current month, complete a new intake with the other provider, and they handle the prescription. Watch for overlap on auto-renewal billing and confirm any dose-tier or formulation differences with the new clinician before your next shipment.

About compounded GLP-1 medicationsCompounded semaglutide and tirzepatide are not FDA-approved finished products. They are prepared by state-licensed 503A pharmacies or 503B outsourcing facilities and are not individually reviewed by the FDA for safety, effectiveness, or quality. Compounders describe these preparations as using the same active ingredient as the approved medicines; the FDA has warned that some compounded products use salt forms, semaglutide sodium or semaglutide acetate, that it considers different active ingredients from the approved drug, and has issued warning letters over marketing that presents a compounded preparation as interchangeable with an approved one. The FDA declared the semaglutide shortage resolved on February 21, 2025 and the tirzepatide shortage resolved in December 2024, so the shortage-era pathway for broad compounding of these drugs has ended. Compounding now proceeds under the ordinary rules: a 503A pharmacy compounding for an individual patient on a prescription, or a 503B outsourcing facility, which compounds in bulk under CGMP and FDA registration rather than per patient. Those rules generally do not cover a product that is “essentially a copy” of an approved drug unless a prescriber documents a change that makes a significant difference for an individual patient. Talk to a clinician about contraindications including personal or family history of medullary thyroid carcinoma or MEN 2.
