Medications

Pros

✓Prescribes only brand-name, FDA-approved GLP-1s - Zepbound, Mounjaro, Wegovy, Ozempic and Foundayo - with no compounded products
✓Publishes a genuine long-term outcome: 20% weight loss achieved at three years, which is a far longer follow-up than the 68-72 week trial data most providers cite
✓Includes 1:1 video coaching and lifestyle support rather than shipping medication and leaving you to it
✓Dedicated insurance navigation support to get the medication covered, instead of assuming cash-pay
✓Available either directly as an individual or through a participating employer
✓Starting price is published openly at $199/month (checked July 28, 2026)

Cons

✗At $199/month for the programme, this is a coaching-led service and the medication cost is separate - what you pay in total depends on your insurance
✗The $199 figure is a 'starting at' price
✗Because it only prescribes brand-name GLP-1s, cost without insurance coverage will be substantially higher than compounded alternatives
✗The 4.5 rating from 1,618 reviews is displayed on Calibrate's own site rather than an independent platform
✗GLP-1 medications are not suitable for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2, or during pregnancy

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
