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

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
