Yes: four rated vendors that sell NAD+ accept a PeptideChecked code, and Ascension Peptides' AFFILIATE50OFF saves the most, at 50% off a first order ($52 on a $104, 1,000mg vial). CHECKED takes 10% off at PSPeptides and Blank Peptides, and Affiliate5 takes 5% off at Licensed Peptides. The cheapest NAD+ we found needs no code: Peptide Plugs listed 1,000mg at $45. The codes were last verified between September 26 and October 12, 2026, and we didn't re-test them at checkout for this page.

NAD+ prices and codes
Single-vial NAD+ prices, including any displayed sale price. Because NAD+ is labeled in hundreds of milligrams, we compare price per 100mg. "After code" is arithmetic, not a checkout quote. Vendors appear in our editors' order, which isn't sorted by score.
| Vendor | NAD+ vial | Price | Code | After code | $/100 mg after code | Score |
|---|
| PSPeptides | 500 mg / 1,000 mg | $79.99 / $105.99 | CHECKED (10%) | $71.99 / $95.39 | $14.40 / $9.54 | 8.5 |
| Blank Peptides | 1,000 mg | $105.00 | CHECKED (10% off the order) | $94.50 | $9.45 | 7.8 |

What each vendor offers on NAD+
- Ascension Peptides: AFFILIATE50OFF is for a first order. The NAD+ page lists volume pricing ($100.88 each for 3, $93.60 each for 10) and, new since our October 7 check, two certificates: Kovera Labs batch 25-05260628 (June 14, 2026) and MZ Biolabs batch 25-01260229 (January 26, 2026). Free shipping over $250. Details: Ascension Peptides coupon code.
- PSPeptides: CHECKED takes 10% off. The 1,000mg vial is the better buy per 100mg. The page links certificates for each size plus older July reports; our October comparison found its August certificates came from North American Diagnostics at 99.90% (500mg) and 99.93% (1,000mg, 974.57mg measured). The page itself doesn't name the lab. Bundles take 3% off 2 vials and 5% off 3+. Details: PSPeptides coupon code.
- Blank Peptides: CHECKED takes 10% off the entire order, so it applies to NAD+ alongside anything else in the cart. On October 22, 2026 the homepage also showed the vendor's own banner, "30% off site-wide with code FALL30." That isn't our code, and we couldn't confirm its terms or end date. Prices show only after a free member sign-up. Details: Blank Peptides coupon code.
- Licensed Peptides: Affiliate5 takes 5% off. Its NAD+ listing offers 100mg, 500mg and 750mg options in packs of 1 to 10, with prices from $129.99 (regular $144.44), and the homepage advertised a "2 for 1 sale" on any vial with no code. We couldn't confirm which option the $129.99 covers, so we didn't work out a price per 100mg. In October we also found its NAD+ certificate's identity line ("All 15 residues confirmed") can't apply to NAD+. Details: Licensed Peptides coupon code.
- Peptide Plugs: no code, but the lowest price here. Volume pricing runs from 5% off at 2 vials to 40% off ($27 a vial) at 10 or more. Its page shows lot 182-03BLK-DK from Freedom Diagnostics, dated August 26, 2026: 99.95% purity and 1,060.15mg measured against the 1,000mg label, with search code Pept2608210517.
- NextGenPeps: no code, but a sale price ($78, down from $98), bulk pricing from 5 vials, and a 10% code for email sign-up. The listing doesn't show a size selector; its image and certificate say 500mg.
How to apply a code
- Go to the vendor through our link, or type its address.
- Add NAD+ to your cart.
- Enter the code in the coupon or discount-code field at checkout.
- Confirm the discount line appears before you pay.
If it doesn't apply, check for a typo, another code already in the cart, a sale item the vendor excludes, or (for Ascension) a previous order. Vendors set and change their own terms. We can't apply or honor codes ourselves.
Which code fits which order
- A first order: AFFILIATE50OFF at Ascension ($5.20 per 100mg) is the largest discount, but Peptide Plugs' list price ($4.50 per 100mg) is still lower without one.
- A repeat order: CHECKED on a 1,000mg vial at Blank Peptides ($9.45 per 100mg) or PSPeptides ($9.54) is the next-best code price.
- Lot-matched paperwork first: Peptide Plugs and PSPeptides have the most complete lot-specific NAD+ documentation, per our NAD+ vendor comparison.
Terms we couldn't confirm
None of PSPeptides, Blank Peptides, Ascension or Licensed Peptides publishes stacking rules we could find. We couldn't confirm whether these codes apply on top of sale prices, volume pricing, Blank's FALL30 banner or Licensed Peptides' 2-for-1 offer. Treat the checkout total as the answer.
NAD+ regulatory status in brief
NAD+ isn't an FDA-approved drug, and it isn't a peptide. FDA's list of bulk substances nominated for 503A compounding places nicotinamide adenine dinucleotide in Category 1, "under evaluation." That covers licensed pharmacies, not research-chemical sellers, and isn't an approval. More in what is NAD+? and FDA peptide regulation in 2026.
Before you use a discount
A lower price doesn't tell you what's in the vial. Match the certificate to your lot with our COA guide and COA checklist, and check measured content against the label, since NAD+ certificates we've read ranged from about 2.5% under to 6% over. PSPeptides' blog publishes human dosing guides, which we count against it in our review.
