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

continuous glucose monitoring

Pros

✓A genuinely different approach: a continuous glucose monitor plus an app that tells you how your own body responds to specific foods, rather than a prescription subscription
✓Published plan pricing: $127/month on the longest plan, $150/month on the mid plan and $225/month on the shortest, each discounted from a higher list price
✓Two CGM sensors per month are included in every plan
✓HSA/FSA eligible, which matters at these prices
✓Registered dietitian support is included, with in-app chat and the option of a face-to-face session
✓A 30-day results guarantee: if you do not learn something new about how your body loses weight, a senior Signos coach audits your data free, described as a $250 value
✓One membership covers the sensors, the app, the coaching and the behaviour-change programme instead of stacking separate subscriptions
✓It pairs sensibly with a GLP-1 rather than competing with one, and the company states medication costs are included in the Signos programme where applicable
✓Stress and sleep tracking are built in alongside glucose

Cons

✗This is not a GLP-1 prescribing service in the way the rest of this site is. If you came here for a semaglutide prescription, Signos is a different kind of product
✗The cheapest per-month rate requires the longest commitment, and six-month plans ship in three-month bundles
✗CGM-guided eating for weight loss in people without diabetes has far weaker evidence behind it than GLP-1 medication
✗HSA/FSA eligibility is qualified - "Possibly, but it depends on your HSA/FSA provider" - and Signos states it is not responsible for reimbursement, with the cancellation policy still applying if your provider refuses
✗The results guarantee pays out in a free data audit, not money back
✗Outcome claims reflect individual Signos patient experiences rather than published clinical studies, which the company discloses
✗Not suitable if you are on insulin without speaking to your own clinician first, which the signup flow asks you to confirm
