Oak Longevity Review (2026): Prices, Marketing Claims and What We Couldn't Verify

How we reviewed this: We didn’t enroll with Oak or test any medication. This review is built from Oak’s homepage, weight-loss and GLP-1 pages and its Terms of Use (all checked October 7, 2026), FDA’s warning-letter database, and dated third-party reports, each cited below. Oak’s checkout runs inside an app that we didn’t complete, so we couldn’t see checkout prices. Our score follows our published methodology.

Verdict

Oak Longevity scores 6.9 with a Caution label. It’s an operating telehealth platform with a published cancellation policy, a clear “not FDA-approved” line on its homepage, and no FDA warning letter in our checks. Its low advertised prices are why people search for it.

What holds it back is transparency. Its own pages show different starting prices without saying which medication or plan they apply to, it doesn’t name the pharmacy that fills prescriptions, and its weight-loss page markets its compounded medication by comparing it to brand-name drugs. That last point is why Oak can’t be Featured under our rules, which exclude providers with marketing that implies sameness with FDA-approved products.

Compounded semaglutide and tirzepatide are not FDA-approved. FDA does not review compounded drugs for safety, effectiveness, or quality.

Pricing: several numbers, no single answer

This is the first thing to sort out with Oak. On October 7, 2026:

• Oak’s homepage said “Prescription weight loss from $119/mo” and “GLP-1 Treatments for weight loss from $119/mo.”
• Its weight-loss page said “Oak’s programs start at as little as $190/month or lower,” and its comparison table listed Oak’s monthly cost as $190/mo.
• Its GLP-1 page listed four treatment types but no prices.

Neither price says which medication or plan length it covers. Other sources have recorded different figures: our own October 2 check found $89 on the homepage, one third-party tracker recorded $89 on September 30, another reported $119 for semaglutide and $185 for tirzepatide on September 16, and Oak’s checkout page as indexed by search engines showed $133 for semaglutide and $199 for tirzepatide (undated). One Trustpilot reviewer described their price rising from $190 to $229 as their dose went up.

Oak’s terms say it offers month-to-month plans and 3-, 6- and 12-month plans, and that the plan length, charge amount and billing schedule are shown before you buy. So the checkout screen is where you’ll see the real number. Write it down, along with the plan length and whether the price changes with your dose.

For context, see where Oak’s advertised prices sit in our cheapest compounded semaglutide list. Oak isn’t in our cheapest compounded tirzepatide list because its own pages don’t publish a tirzepatide price.

How Oak markets compounded GLP-1s

Oak’s homepage footer says “Compounded medications are not FDA approved,” and its FAQ explains that compounded medication is made by a licensed U.S. compounding pharmacy for an individual patient. That’s good.

Its weight-loss page takes a different tone. Its comparison table is headed “Same science. Fraction of the price.” and includes a “Same Active Ingredient” row next to brand-name medications. Its FAQ says the compounded medications Oak offers “contain the same active ingredient as brand-name medication.” In the page text we reviewed, we didn’t find a statement on that page that the compounded products aren’t FDA-approved.

Why that matters: in March 2026, FDA announced warning letters to 30 telehealth companies over compounded GLP-1 marketing, including claims that implied the compounded products matched FDA-approved drugs. We found no FDA warning letter to Oak. But our methodology applies a safety-score deduction to any provider whose marketing implies sameness with approved products, and that rule applies here. Compounded drugs aren’t reviewed by FDA for safety, effectiveness or quality, and they aren’t generics of any brand-name drug.

Refunds, cancellation and early-exit charges

Oak’s Terms of Use (checked October 7, 2026) include a refund, shipping and cancellation policy:

• If you’re not approved, you’re only charged if a licensed provider approves treatment; otherwise any card authorization is released and any amount collected is refunded in full.
• Once approved and sent to the pharmacy, an order can’t be canceled and isn’t refundable, even if you cancel your account or try to stop the shipment with the carrier.
• Cancel anytime through the patient portal, by email or by phone. Cancellation takes effect at the end of the billing period you’ve already paid for, which isn’t refunded. Orders paid and within 48 hours of shipment still ship.
• Leaving a multi-month plan early costs extra. If you cancel a plan with more than one scheduled payment, Oak charges back the discount on the months you received: the difference between its month-to-month price and your plan’s monthly price, times the months received. Its own example: on a $209/month 12-month plan with a $299 month-to-month price, canceling after 6 months costs $540. For plans paid in full, Oak refunds unshipped months minus that same discount.
• Medical changes: if your provider stops or changes treatment for medical reasons, no early-cancellation charge applies.
• Disputes go to binding arbitration, under Delaware law, per its terms.

The early-exit charge-back is unusual among the providers we track. If you’re unsure you’ll stay on a multi-month plan, the month-to-month plan avoids it.

Pharmacy, clinicians and safety record

• Pharmacy: Oak says every prescription is filled by licensed U.S. pharmacies, but we didn’t find the pharmacy named on its pages or in its terms. Ask before you pay. Our guide to 503A vs. 503B pharmacies explains what to ask.
• Clinicians: Oak’s terms describe it as a facilitator that contracts with independent physicians and nurse practitioners; it doesn’t name a medical group. Its homepage says providers are licensed in every state it ships to.
• FDA: We found no FDA warning letter to Oak or its operator in our October 2026 checks.
• LegitScript: Oak’s site displays a LegitScript seal with a link to LegitScript’s checker. Use that lookup to confirm the listing yourself.

Reputation

Oak’s review base is small. Third-party reviewers recorded about 4.4 from roughly 54 Trustpilot reviews in August 2026, and noted that only a minority were from the past 12 months. Oak’s own weight-loss page shows a “Rated 4.6” badge and a widget “based on 46 reviews.” Positive reviews mention fast approval and responsive support. A third-party report from August 2026 describes negative reviews about non-delivery and packages left in summer heat. That’s a reason to ask how Oak ships and what happens if a package arrives warm; FDA’s consumer page on compounded GLP-1s warns about medication that isn’t kept at the right temperature in transit.

What we like

• Low advertised prices relative to most of the market.
• A written refund and cancellation policy, including a full refund if you aren’t approved.
• “Not FDA approved” disclosure on its homepage and GLP-1 page.
• No FDA warning letter found.

What to watch

• Inconsistent prices across its pages, with no medication or plan named.
• Brand-name comparison marketing on its weight-loss page.
• Unnamed pharmacy and no named medical group.
• Early-exit charge-backs on multi-month plans.
• Small, older review base.

If price is your main reason for looking at Oak, compare it with Trimi, which publishes every plan price and names its pharmacy, and with our Gala review and Fridays review.

Bottom line

Oak may offer a low price, but its pages don’t tell you clearly what that price buys, who fills your prescription, or how it compares with an FDA-approved drug without leaning on brand-name comparisons. If you consider it, confirm the medication, plan length, total cost and pharmacy at checkout, and choose month-to-month unless you’re sure you’ll finish a multi-month plan. Whether any compounded GLP-1 is right for you is a decision for you and a licensed clinician. See all options in our rankings.
