Medications

semaglutidetirzepatide

Pros

✓The largest verifiable review base of any provider in this batch: the Trustpilot profile for refills.com showed a 4-star TrustScore from roughly 1,244 reviews when we checked
✓No membership or app fees, stated as a headline promise: "Never Pay for Monthly Memberships or App Fees"
✓All dosages cost the same - "We don't charge you based on dosage changes" - which removes the titration price trap that catches most compounded GLP-1 patients
✓Both a GLP-1 (semaglutide-class) and a GIP + GLP-1 (tirzepatide-class) injectable are offered
✓A published phone number, 888-458-5061, and support@refills.com, with 24/7 health-concierge support advertised
✓Free and discreet shipping on every order
✓Unusually candid disclaimers: it states plainly that compounded drug products are not approved or evaluated by the FDA, and that Refills Health is not a medical services provider but a technology platform
✓It names its clinical partners - Beluga Health, Bask Health and Wasef Health - rather than referring vaguely to "our providers"
✓Certificates of Analysis are available on request for any batch
✓LegitScript certification is displayed

Cons

✗Pricing is quoted per day, not per month. "GLP-1s from $5/day" reads as cheap but is $150 a month, and the site never states a monthly figure
✗Refills is a technology platform, not a medical provider. It does not manufacture or dispense medication and does not employ the clinicians who prescribe
✗All prescription sales are final. State and federal rules do not allow returns of dispensed prescription medication, and once your card is charged and the package is handed to the carrier there is no refund
✗Returns are only accepted on unopened, non-prescription items within 30 days, and you pay the return shipping
✗It does not ship refrigerated products, which the returns page presents as a benefit ("your product will not be affected by increased transit time") but which is worth understanding before you order
✗The medication is compounded, so it has not been evaluated by the FDA for safety, quality or efficacy
✗Available across the US but explicitly not in the District of Columbia
✗Before/after testimonials headline losses of 40 to 120 pounds. The disclaimer that results are not typical is present but far less prominent than the numbers

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
