Oak
Oak prescribes compounded and brand-name GLP-1s after an online intake, and lists sermorelin, NAD+ and glutathione. Its marketing pages, its checkout and its terms disagree on price, on billing and on whether the dose changes the cost.
Review by Molly Ward, goal-guide writer · Updated October 2026
The short version
Oak's checkout is clear about what you pay today and why you might pay more later. Its marketing pages are not. Trust the checkout figure and its FAQ, which says each dose step adds $50 to $75, over the "one price, all dosages" banners elsewhere on the site.

Lowest listed: Sermorelin injection, from $133 per 4 wks ($144.08 a calendar month, our calendar-month conversion)
Every state but West Virginia and Mississippi
Visit Oak →Oak is a cash-pay weight-loss telehealth. It sells compounded semaglutide and tirzepatide, an oral semaglutide, and brand-name Ozempic, Wegovy, Mounjaro and Zepbound. A longevity page sells NAD+ and sermorelin as injections under the skin, and the checkout adds glutathione as a vial with supplies. The same page markets tesamorelin, which is a brand-only drug and is not priced here.
What Oak prescribes, by goal
Weight
- SemaglutideFDA-approved
- Injection (compounded)From $200/mo
- Oral (compounded)From $245 per 4 wks$265.42 a calendar month, our calendar-month conversion
- TirzepatideFDA-approved

Compounded semaglutide is $200 a month, or $133 a month prepaid for three months. Tirzepatide is $250, or $199 prepaid. The checkout FAQ says each dose step costs about $50 to $75 more, which contradicts the banner's "one price, all dosages". No dose in milligrams is printed.
Longevity
- NAD+Legal to compound
- Injection (compounded)From $175/mo
- GlutathioneLegal to compound
- Injection (compounded)From $135/mo
NAD+ is an injection under the skin, taken a few times a week as prescribed. The NAD+ page prices it at $175 a month, regularly $199, while the checkout shows $133 against a struck $200. Glutathione is $135 a month at checkout, struck from $150. No strength is printed for either.
Recovery
- SermorelinLegal to compound
- Injection (compounded)From $133 per 4 wks$144.08 a calendar month, our calendar-month conversion
Sermorelin is the only recovery product listed; the sleep panel covers what Oak says about it, which is little.
Sleep
- SermorelinLegal to compound
- Injection (compounded)From $133 per 4 wks$144.08 a calendar month, our calendar-month conversion
Sermorelin is an injection under the skin, usually taken nightly as prescribed. The marketing page holds its price until after the assessment, but the checkout shows $133 for a four-week supply. No strength is printed.
Each “From” figure is the seller’s own starting price, in the unit the seller states. Where a required fee or a package length changes what one month costs, the smaller line under it is our arithmetic, not a figure the seller prints. Compounded preparations are not FDA-approved.
Who prescribes
A licensed clinician
The checkout FAQ says a physician licensed in your state reviews your intake, and the weight-loss page describes the prescribers as trained in obesity medicine. The same FAQ lists one telehealth provider group, NVP Medical Group, as the network Oak works with. The terms describe independent physicians and nurse practitioners. No individual clinician is named.
You fill in an intake, upload a body photo, a selfie and your state ID, and check out. A physician usually reviews it within a few hours, and a video visit is optional. Each month you fill in a refill form for a clinician to approve, and you can chat with your physician in the dashboard.
Are labs required?
Not required
No intake or FAQ page asks for labs. The terms mention optional lab-testing partners without saying what they cost.

What it claims, and what it cites
Oak's weight-loss numbers come from its own members. It reports 14.9% loss within a year and 27.1 pounds in six months, both from self-reported member data. A line about lowering heart risk by up to 14 percent carries no source. The site says its benefits rest on third-party studies it does not link.

- Tesamorelin
- Approved only as Egrifta, for excess abdominal fat in adults with HIV-associated lipodystrophy. Its label says it is not indicated for weight loss. Egrifta became a biologic (BLA) on March 23, 2020, and FDA says compounded versions of these products do not qualify for the 503A or 503B compounding exemptions.
- Sildenafil, tadalafil and tretinoin
- Sexual-health and acne medicines. None is a peptide.
How it bills
The checkout says billing is monthly with no subscription and no automatic charge, and that you choose to renew each month. The terms say most prescriptions renew on a recurring basis until you cancel in your account. You are not charged until a physician approves you, and you are refunded if you are not approved. Once medication ships there is no refund. Consults and shipping are free.
