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
