Pros

  • The quality documentation is genuinely thorough for this category: HPLC and mass spectrometry on every lot, a signed certificate of purity shipped with every order, and a public lab-report library you can read before buying
  • Endotoxin testing (LAL assay) and microbial screening to USP standards on every batch before release
  • Full batch traceability - each vial traced to its production lot, raw materials and test results
  • States an average of 99.3% HPLC purity across all batches and publishes the underlying numbers rather than only the claim
  • Partner labs described as GMP-aligned, with documented SOPs and controlled environments
  • Pricing is straightforward and published: individual peptides run roughly $59.99 to $159.99, with free shipping over $150 (checked July 28, 2026)
  • The research-use-only status is disclosed up front behind an acknowledgement gate, not buried in a footer after checkout
  • A published phone number and a catalogue organised into peptides, blends, sprays and capsules, with a reference database

Cons

  • This is not a treatment and cannot lawfully be sold as one. Everything here is labelled for research use only and explicitly not for human consumption. If you are reading this site to find help with weight loss, this is not an option - it is laboratory material
  • There is no clinician at any point. Nobody takes a history, nobody checks your contraindications, nobody sets a dose and nobody monitors you. The safety net that every licensed provider on this site provides simply does not exist here
  • A certificate of analysis tells you what is in the vial. It tells you nothing about whether the contents are safe for you, what dose is appropriate, or how it interacts with your medications
  • Products arrive as lyophilised powder requiring reconstitution, and bacteriostatic water, syringes and other supplies are not included - so self-administration would also mean improvising sterile technique
  • Peptides such as BPC-157 and TB-500 appear on the FDA's list of substances that raise significant safety concerns for compounding, and have little or no published human trial evidence
  • There is no prescription, no pharmacy oversight and no adverse-event reporting pathway. If something goes wrong there is no clinical record and no provider to call
  • No Trustpilot or BBB record exists, so there is no independent consumer feedback of any kind
  • Our rating reflects suitability for someone seeking treatment, which is what this site compares. As a laboratory supplier the documentation is strong; as a route to a GLP-1 or peptide for your own health it is the wrong door, and a licensed provider is the right one

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
