Medications
semaglutidetirzepatide
Pros
- ✓Per-product prices are listed openly on the homepage rather than hidden behind a quiz: semaglutide from $197/mo, tirzepatide from $297/mo, NAD+ from $129/mo, sermorelin from $129/mo, B12-MIC from $97/mo (checked July 27, 2026)
- ✓Cancel or pause at any time with no long-term commitment, managed from your own account rather than by emailing support
- ✓Publishes both the dispensing pharmacy's location and the medical provider's address, which is unusually specific for this category
- ✓1-on-1 calls with US doctors are part of the programme, not an upsell
- ✓A satisfaction guarantee is advertised alongside progress tracking and built-in guidance
- ✓Trustpilot rating of 4.1 across 454 reviews gives at least a moderate independent signal
- ✓Wide catalogue if you want more than weight care - NAD+ in three delivery formats, sermorelin, enclomiphene and an 80-biomarker DNA panel
Cons
- ✗The affiliate link for this offer lands on RNK's NAD+ funnel, not its GLP-1 pages, so anyone following the link for weight loss arrives at a longevity product and has to navigate away
- ✗'Full pricing details are shown during checkout' - so the advertised 'from' prices are a floor, and what you actually pay is not visible until you are committing
- ✗We could not find an explicit 'not FDA-approved' disclosure for the compounded medications. Nearly every competitor states this plainly; RNK describes its products only as 'USA Compounded: Lab-tested, high-purity'
- ✗GLP-1 pricing is at the higher end - $197 for semaglutide and $297 for tirzepatide, where several rivals advertise under $150
- ✗The NAD+ landing page promises you will 'LOOK, FEEL & PERFORM 10 YEARS YOUNGER' with 'the most powerful NAD+ protocol on the market' - claims with no cited evidence
- ✗The 'satisfaction guarantee' and 'Risk FREE' language is used without published terms defining what either actually entitles you to
- ✗No BBB profile or complaint history to check
- ✗As with all compounded GLP-1s, no efficacy data specific to RNK's own patients is published

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
