Calibrate
View full Calibrate review →Pros
- ✓Prescribes only brand-name, FDA-approved GLP-1s - Zepbound, Mounjaro, Wegovy, Ozempic and Foundayo - with no compounded products
- ✓Publishes a genuine long-term outcome: 20% weight loss achieved at three years, which is a far longer follow-up than the 68-72 week trial data most providers cite
- ✓Includes 1:1 video coaching and lifestyle support rather than shipping medication and leaving you to it
- ✓Dedicated insurance navigation support to get the medication covered, instead of assuming cash-pay
- ✓Available either directly as an individual or through a participating employer
- ✓Starting price is published openly at $199/month (checked July 28, 2026)
Cons
- ✗At $199/month for the programme, this is a coaching-led service and the medication cost is separate - what you pay in total depends on your insurance
- ✗The $199 figure is a 'starting at' price
- ✗Because it only prescribes brand-name GLP-1s, cost without insurance coverage will be substantially higher than compounded alternatives
- ✗The 4.5 rating from 1,618 reviews is displayed on Calibrate's own site rather than an independent platform
- ✗GLP-1 medications are not suitable for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2, or during pregnancy
