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
NAD+

Pros

  • It cites its sources. Fourteen PubMed and journal references are linked directly from the claims they support, which is far more than any competing longevity brand we have reviewed
  • It explicitly disclaims celebrity endorsement: 'Dr. Conlon, David Sinclair, Joe Rogan, all other referenced quotes, and studies does not endorse the claims, views, statements, or products offered by Viking Man'
  • The product is described as 'compounded and made-to-order by a licensed pharmacy' rather than being passed off as a manufactured drug
  • The standard FDA disclaimer is present - statements not evaluated by the FDA, not intended to diagnose, treat, cure or prevent any disease
  • A published phone number, a real Utah street address and an email address
  • Free shipping on US orders, the prescription is included in the price, and the company advertises free unlimited doctor follow-ups
  • State eligibility is checked before you can sign up, so you find out early if you are outside the service area
  • NAD+ sits alongside a broader men's health service (ED, hair, sleep), so there is somewhere to go if NAD+ is not the right answer

Cons

  • The advertised '4.9 (2700+ Reviews)' does not match the verifiable Trustpilot score of 3.0 from 3 reviews
  • The citations look rigorous but do not support the claims made. Reference *6, used for 'helps with metabolism and weight loss', is a study of a NAD+ intermediate in diet- and age-induced diabetes in MICE. Others are mechanistic papers or literature reviews, not human outcome trials
  • 'Turn Back The Biological Clock', 'Slowing & Reversing Aging Has Never Been Simpler' and claims about repairing DNA are strong anti-aging assertions that no NAD+ product has demonstrated in humans
  • 'Shown to help with weight loss' and 'Lose weight easier' appear repeatedly. NAD+ is not a weight-loss treatment, and if that is what you are looking for this is the wrong product
  • Heavy artificial urgency throughout: 'In Stock (67)', 'Selling Fast: 82 Packs Sold In Last Hour', 'Back In Stock - Order Now', and a delivery-date countdown
  • The headline price is a 79% discount - $47.99 marked down to $10 per dose - presented as the standing offer rather than a genuine limited promotion
  • Pricing is per dose with no published pack size or dosing frequency, so the actual monthly cost is unknowable until after you sign up. The figure shown here is the regular per-dose price, not a monthly total
  • The page says 'FDA Registered Pharmacy' but never states the consequence - a registered facility is not the same as an FDA-approved medicine, and this compounded product has not been evaluated by the FDA for safety, efficacy or quality
  • The David Sinclair 'fountain of youth' quote is placed prominently at the top of the page while the non-endorsement disclaimer sits in fine print at the very bottom
  • Evidence that injected NAD+ produces meaningful anti-aging, cognitive or metabolic benefits in healthy adults remains limited
