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

Medications
semaglutidetirzepatideliraglutide
Pros
- ✓Programme prices are published per four-week cycle rather than hidden behind an intake: semaglutide from $299, and a range of other programmes from $179 to $600
- ✓Programmes cover medication, supplies and 24/7 access to your care team through a HIPAA-compliant platform
- ✓The partner pharmacy is described as a US-based, FDA 503A licensed facility
- ✓Same-day telehealth consultation with a board-certified physician after you complete the questionnaire
- ✓Delivery quoted at 3-5 business days with tracking supplied
- ✓An automatic refund mechanism that most competitors do not offer: "Subscription recurring payment auto-refund if monthly reassessment is not filled" - if you do not complete the monthly review, you are not charged for medication you were never reassessed for
- ✓BMI and progress tracking are built into the programme
- ✓A broad catalogue including liraglutide, which relatively few telehealth providers offer
Cons
- ✗The liraglutide programme does not include the medication. The page states outright: "The cost of Liraglutide medication is not included in this program" - the price buys the telehealth wrapper only, and the pharmacy negotiates the drug cost with your insurer separately
- ✗The same liraglutide page calls liraglutide "FDA-approved" while the pharmacy fulfilling it is described as a compounding pharmacy, which muddles what you are actually buying
- ✗Prices are quoted "from" a figure every four weeks, and four-weekly billing means 13 payments a year rather than 12
- ✗The dispensing pharmacy is not named
- ✗No phone number is published
- ✗No insurance billing, and HSA/FSA acceptance is not stated
- ✗The site markets a very wide catalogue of programmes, which makes it hard to tell how much clinical attention each one gets
