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 September 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.

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 separate anti-aging list carries sermorelin, NAD+ and glutathione, but no page says whether they are injected or taken another way.

NAD+ and glutathione sit on Oak's anti-aging list at $133 and $135 a month for a four-week supply. Neither page says whether the product is injected or taken another way, or at what strength.
Recovery

Sermorelin is the only recovery product listed; the sleep panel covers what Oak says about it, which is little.
Sleep

Listed by the seller; no price we hold.
Sermorelin is $133 a month for a four-week supply. Oak does not say whether it is an injection, and prints no strength or schedule.
Prices are the seller’s own published starting figures, each in the unit the seller states. 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 terms say they are independent physicians and nurse practitioners in a contracted medical group. No prescriber 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, and the site says its benefits rest on third-party studies it does not link.

Sold by Oak, not listed here
- 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.
