Pros

✓A published, all-in price for the compounded semaglutide programme: $250.00 with home delivery included
✓Brand-name options are listed alongside compounded ones - Ozempic, Mounjaro, Saxenda, Wegovy, Zepbound and Contrave all appear in the medication catalogue
✓A published phone number, (214) 466-6618, plus email and text support - more contactable than most telehealth weight-loss services
✓Coverage across all 50 states plus the District of Columbia
✓Long service hours: Monday to Friday 5am to midnight CT, weekends 6am to 1am CT
✓No appointment needed - visits happen online when you start them
✓A "Subscribe & Save" programme brings general visits down to $12, useful if you use the service for more than weight loss
✓An RX Savings Card is offered to reduce prescription costs
✓Every programme includes a licensed provider visit that reviews your history and confirms the medication and dose

Cons

✗The $250 compounded semaglutide price is presented on the medication page, but the weight-loss programme pages do not carry a comparable published price for every option
✗Compounded medication is not FDA-approved and has not been reviewed by the FDA for safety, quality or efficacy
✗No refund or cancellation policy is published on the weight-loss pages
✗Insurance is not addressed on the weight-loss pages - this reads as a cash-pay service
✗Patient testimonials are duplicated verbatim across the page, which undermines their value as evidence
✗It is a broad urgent-care telehealth service first and a weight-loss provider second, so there is no dedicated coaching or nutrition programme
✗HSA/FSA acceptance is not stated

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
