Best NAD+ Suppliers (2026) — Ranked by Batch Testing

NAD+ price (Oct 2026): not captured this cycle. Free shipping over $300.

For NAD+: Paramount's NAD+ price was not captured in this review cycle, so it is listed without one rather than estimated — its ranking here rests on the proof stack its score already reflects. Every lot in its catalog carries an Accumark Labs COA posted on the product page, with 16 prior lots still clickable, so the certificate for the actual batch can be inspected before paying. The decisive detail remains the purity refund guarantee: if a vial fails HPLC testing at any licensed lab, Paramount refunds the purchase and reimburses the $100 testing fee — a policy that matters more, not less, on a large-format vial. Synthesis is in-house (Irvine, CA, 12+ years) and checkout is standard cards with prices visible without an account. We reviewed Paramount in depth here.

NAD+ price (Oct 2026): not captured this cycle. Free shipping over $150.

For NAD+: Kylo's NAD+ price was not captured in this review cycle, so it is listed without one rather than estimated. What the score reflects is the widest published panel in this set: per-lot COAs from three named laboratories (Janoshik, Freedom Diagnostics, Vanguard) covering HPLC purity, LC-MS identity, net content, plus heavy metals, sterility and endotoxin — posted on the product page and archived in a public COA library. On a large-format vial, the net-content line is the one to read first. It is also the payment leader in this set (cards and Apple Pay, same-day shipping before 2 PM PT). Multi-unit discounts (5% / 10%) and the $497 half-price lifetime membership change the math for high-volume labs.

NAD+ price (Oct 2026): not captured this cycle. (Everest's BPC-157 10mg lists at $44.99 before stacked discounts.) Free shipping over $150.

For NAD+: Everest's NAD+ price was not captured in this review cycle, so it is listed without one rather than estimated — its ranking here rests on the proof infrastructure the score already reflects. Freedom Diagnostics runs seven tests per lot (HPLC purity, LC-MS identity, net content, endotoxins, heavy metals among them), the full COA sits on the product page, and a QR code on the vial links back to the batch record — the strongest per-lot documentation pattern in this set alongside Paramount. Checkout is the trade-off: no cards, Zelle and Pay by Bank only, turned into stacked rail discounts (5% bank, 10% Zelle) elsewhere in its catalog. A 4.9★ Trustpilot rating and free returns complete the trust stack.

NAD+ price (Oct 2026): not captured this cycle. Free shipping over $150.

For NAD+: BioEdge's NAD+ price was not captured in this review cycle, so it is listed without one rather than estimated. What it does right is the single most important thing — a batch-specific COA on the product page (independent HPLC plus mass spectrometry) — the pattern a buyer of a large-format vial should look for before anything else. US lyophilization is called out explicitly against imported, relabeled vials, pack discounts up to 15% apply automatically in the cart, and same-day shipping runs before 3 PM ET. What holds the score back: payment options were not displayed on the product pages we reviewed, and the testing laboratory is not named in the published materials.

NAD+ prices (Oct 2026): 500mg $60 · 1000mg $90 — sold on the store as "NAD+X." 31 products; free shipping over $150.

For NAD+: two things a buyer should know. First, the naming: Vonox lists this compound as "NAD+X" rather than NAD+, so it will not surface under the standard search term — even though the 1000mg vial is one of the products featured on its homepage, listed at $90 (marked down from $250). Second, the sizes and the proof: Vonox is the only store in this table with NAD+ prices captured in both standard formats this cycle — $60 for 500mg and $90 for 1000mg — and every batch is tested by an independent laboratory (HPLC-UV for purity, LC-MS for identity) with the Certificates of Analysis published in an open COA library readable before ordering — a stronger proof habit than several larger stores show. Vonox is a registered US company (VonoxLabs LLC, Charleston, SC, public address) with products made in the USA and a 21+ age gate. The weaknesses are the same ones that hold it mid-table in the main ranking: checkout is bank transfer and Zelle only, the COAs live in a library rather than on the product page, and as a new brand it has no public reviews yet to cross-check.

Reputation (Oct 2026): Trustpilot 4.8★ from roughly 3,000 verified reviews. An NAD+ reference price was not captured this cycle.

For NAD+: Infiniwell is the reputation-led entry — its 4.8★ Trustpilot score across ~3,000 verified reviews is the deepest public track record in this set, and roundups in this niche commonly position it for oral/capsule formats rather than the lyophilized-vial catalogs the rest of this table sells. Lot-level COA documentation of the kind the top four publish was not part of its public proof stack in the materials reviewed, so its testing and COA scores are marked † and held conservatively. If published batch documentation appears, this entry gets re-scored.

Reputation & policy (Oct 2026): Trustpilot 4.6★ · 60-day money-back guarantee · private buyer Discord. An NAD+ reference price was not captured this cycle.

For NAD+: Amino Club's trust mechanism is policy rather than paperwork — the 60-day money-back guarantee is the longest in this set, backed by a 4.6★ Trustpilot rating and an active private Discord where buyers compare notes. Batch-level testing documentation was not published in the public materials reviewed for this ranking, so its proof scores are marked † and held conservatively. Amino Club is formally invited to submit its COA documentation for re-scoring — publishing the paperwork is the fastest way up this table.
