Every NAD+ vendor that passes the gate, by PSR score
42 vendors, highest PSR score first; equal scores are listed alphabetically. Price per mg is matched at 500mg, the size most carriers sell, so vials compare like for like. The certificate column is the vendor’s certificate for NAD+ only. Affiliate status never affects the order (how we keep it separate).

Listed separately: 23 vendors outside the ranking
These carry NAD+ but do not meet our testing gate, so they are never placed in the ranking above, whatever their score. The gate records what we could verify; it is not a finding of a quality or safety problem.

Best NAD+ vendors: frequently asked questions
Who is the best NAD+ vendor?
By PSR score, Southern Aminos is the highest-rated open store carrying NAD+ that passes our testing gate (8.09/10, Strong). Amino Club (8.08) and DAAVY Research (8.01) follow. The certificate each of them posts for NAD+ is shown beside the score, so a reader can check it before buying.
Where can I buy NAD+ with a discount code?
11 affiliate partners carrying NAD+ pass our testing gate and give readers a code that applies to it. The highest rated is DAAVY Research (code PSR10, 10% off). We may earn a commission on those links; it never changes a score or a rank.
How are these NAD+ vendors ranked?
By PSR score, the published vendor score out of 10, built from lab testing, certificate verification, pricing, shipping, operating history and reviews under the rules on How We Rate. Equal scores are listed alphabetically. Price per mg and the certificate for NAD+ are shown but do not change the order, and affiliate status never does.
Why are some NAD+ vendors listed separately?
23 vendors carrying NAD+ do not meet our testing gate: third-party testing could not be established or independently verified. They are listed below the ranking rather than in it. The gate records what we could verify; it is not a finding of a quality or safety problem.
How do I check a NAD+ certificate of analysis?
Open the certificate from the vendor's row, confirm it names NAD+ and a batch, then look up the verification key on the testing laboratory's own site. 44 of the 65 NAD+ certificates we track were confirmed at the lab. Our guide on how to read a peptide COA walks through each field. For laboratory research use only.
