Medications
semaglutidetirzepatide
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

Medications
semaglutidetirzepatide
Pros
- ✓Among the lowest advertised prices in the category: compounded semaglutide from $119/month and tirzepatide from $185/month (checked July 27, 2026)
- ✓One price at every dosage, so titrating up does not increase what you pay
- ✓Free shipping and free health coaching are included, with no separate membership fee
- ✓Same-day approval is offered and no video call is required, which suits people who cannot take time out for an appointment
- ✓Publishes a phone number, an email address and the legal entity behind the brand
- ✓The compounded explanation distinguishes 'not FDA-approved as finished products' from the ingredients and conditions used, which is more accurate than the blanket claims some rivals make
- ✓A comparison calculator and a public price comparison table let you check the maths before signing up
- ✓Cancellation can be done from your own account by cancelling the prescription or deleting the account, rather than only by emailing support
Cons
- ✗The homepage advertises 'One price · All dosages · No subscriptions', but the terms contain a 'Refund, Shipping, Cancellation Policy' describing how cancelling will 'stop any future subscription renewals or charges'. Those two statements cannot both be right
- ✗A third price appears in Oak's own comparison table, which lists 'Oak $167/mo' against headline rates of $119 and $185. The table never explains which product $167 refers to
- ✗'Same Active Ingredient' is used as a feature row comparing Oak to brand-name drugs. That is the precise claim the FDA cited in a February 2026 warning letter to another telehealth firm, on the basis that it implies FDA approval the compounded product does not have
- ✗Promotions stack confusingly - a 'SUMMER SALE - Save up to 60% vs. retail pricing' banner sits alongside a separate '$200 off new patient offer' with no terms for either
- ✗Trustpilot carries only 53 reviews, far too few to corroborate the '10,000+ Satisfied Patients' claim
- ✗There is no dedicated refund policy page; refund terms are buried inside the general Terms of Use
- ✗The Terms of Use include a dispute resolution and arbitration agreement
- ✗'Up to 50% cheaper than competitors' is asserted repeatedly in a scrolling banner without naming the competitors or the basis for the figure
