Medications

semaglutidetirzepatide

Pros

✓A full product price list is published rather than a single teaser figure: semaglutide injection $249, tirzepatide injection $329, semaglutide capsules $249 and tirzepatide capsules $349 for the first month (checked July 27, 2026)
✓Brand-name options are offered and priced openly too - Ozempic $1,299, Wegovy $1,349 and Zepbound $1,069
✓The plan ladder is shown with each rate: $249/mo monthly, $219/mo on 3 months, $199/mo on 6 months and $194/mo on 12 months
✓The price is stated to include the consult, medication, supplies, shipping and support, with no separate membership fee
✓Oral capsule versions of both semaglutide and tirzepatide are available for people who do not want injections
✓Plans can be cancelled or changed at any time
✓The site states plainly that 'Prescription is not guaranteed' rather than implying approval is automatic
✓A named, credentialled physician is associated with the service rather than an anonymous 'medical team'

Cons

✗Every headline price is labelled 'For the first month'. What you pay from month two is not shown anywhere on the product screen, so the ongoing cost is unknown until you are further into the funnel
✗You pay at checkout before a provider reviews your case - the site confirms 'After checkout, a provider will review your information to determine if treatment is right for you' - so your money goes first and eligibility is decided afterwards
✗There is no independent review signal at all: no Trustpilot profile, no BBB file, and no rating displayed on site
✗Brand-name pricing is far above the manufacturers' own direct-pay programmes - $1,349 for Wegovy and $1,069 for Zepbound against considerably cheaper NovoCare and LillyDirect routes
✗No customer phone number is published; the only contact is an email address
✗The supervising physician's board certification is in plastic surgery, not obesity medicine, endocrinology or internal medicine
✗The banner copy - 'No Hidden Fees', 'Free, Expedited Delivery', 'Doctor-led Plans & Coaching' - is word-for-word identical to TrimRx's, indicating a shared white-label funnel rather than an independently built service
✗Product prices only render once JavaScript loads; with scripts blocked the weight-loss category reads 'No products found for Weight Loss'

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
