NAD+ Coupon: $10.40 per 100 mg Halves to $5.20

One code, one listing, four numbers that change.

The vial holds ten lots of 100 mg, so the rate is just the price with a decimal point moved: $104.00 becomes $10.40, $52.00 becomes $5.20. Nothing subtler is happening.

Two things about the last row are worth stating plainly, because coupon pages routinely get them wrong. Halving a price doubles the material per dollar, and those are the same fact reported twice. A page that tells you it saves 50% and then tells you it gets 100% more per dollar has not found a second discount.

The other is that the $179.99 struck through on the product page is not the list this code works from. The everyday price is $104.00, and $52.00 is half of that.

Ascension publishes a separate bulk ladder: 3% off each vial at three units, 5% at five, 10% at ten. Those percentages come off the $104.00 list price, not off the code price, which is what makes the comparison one sided.

The deepest tier available is $9.36 per 100 mg. That is 80% above the $5.20 one vial costs with the code, and reaching it means spending $936.00 and taking delivery of ten grams of material with a fixed refrigerated shelf life once any of it is made up.

Put another way, ten vials on the 10% tier cost $936.00 for 10,000 mg. Eighteen vials bought one at a time at the code rate would cost $936.00 for 18,000 mg. The ladder is not a route to a lower rate; it is a route to a larger order.

Free carriage starts at $250. The code halves the number that threshold is measured against, which moves the line by several vials.

• One vial with the code is $52.00, nowhere near it.
• Four vials with the code is $208.00, still short.
• Five vials with the code is $260.00 and clears it.
• At list, three vials on the 3% tier is $302.64 and clears it.

Whether the cart measures the threshold on the pre-code or post-code subtotal is a checkout rule rather than a published one, and the payment screen is the only place that can settle it. Assume the stricter reading when planning, and treat the looser one as a bonus if it appears.

Shipping matters more than usual on a single vial order precisely because it is a fixed charge divided by a fixed quantity. A $12.00 charge on one $52.00 vial adds $1.20 per 100 mg, taking the effective rate to $6.40 and eating 23% of the discount. On a five vial order that clears the threshold it adds nothing. The full landed arithmetic sits on our NAD+ price page.

Four things about the scope of this discount are worth knowing before you plan an order around it.

There is one NAD+ listing, so there is no vial size to optimise. That is unusual on this store. With retatrutide the interesting question is whether the 10 mg or the 30 mg vial gives the better rate, which our retatrutide coupon page goes into. With NAD+ the only variables are how many vials and whether the code is applied.

The tier discounts are published as fixed per item amounts, and they reconcile. The listing shows $3.12 off each at three units, $5.20 at five and $10.40 at ten, which are exactly 3%, 5% and 10% of the $104.00 list. Worth noticing that the 5% per item saving, $5.20, is the same figure as the cost of 100 mg with the code applied. The tier saves you a tenth of a vial; the code saves you half of one.

The struck-through $179.99 is not the basis for anything. The everyday price is $104.00 and PEPTIDEDECK works from that. A coupon page that computes 50% off $179.99 and reports $89.99 has quoted a saving that does not exist.

A code is vendor configuration, not a contract. Discount codes get withdrawn, capped, restricted to first orders or quietly replaced, and no store owes anyone notice. Every figure on this page was checked on 20 August 2026. The test that settles whether it is still live takes ten seconds: add the vial, enter the code, and see whether the order summary reads $52.00. If it does not, nothing else on this page applies to your cart.

We do not know, and neither does any page that tells you it does.

Here is the honest position. The tiers are published on the product listing. The code is published as a flat 50% off. Nothing published anywhere states how a cart resolves the two when both conditions are met, and cart rules of this kind are ordinary commerce configuration that a store can change without announcing it. Anyone quoting you a stacked rate has either observed it once on their own screen or made it up.

What the arithmetic would look like if they did stack is easy enough to state as a conditional. Three vials at $100.88 each is $302.64, and a further 50% would be $151.32, or $5.04 per 100 mg. Ten vials at $93.60 each is $936.00, and a further 50% would be $468.00, or $4.68 per 100 mg. Those are hypotheticals, and this page is not claiming either of them is available.

The practical version: add what you want, enter PEPTIDEDECK, and read the order summary before paying. If the tier survives the code, the total will be below half the tier total. If it does not, you get the flat 50% and that is still the best published rate on the listing.

Half price on the wrong material is not a saving, and NAD+ is the compound where that sentence has a documented case behind it rather than a rhetorical one.

On 30 October 2024 FDA published a notice stating it "is aware of compounders using food-grade nicotinamide adenine dinucleotide (NAD+) sold by repackagers to make intravenous products", and that food-grade ingredients "are not suitable for compounding sterile drugs without appropriate processing, due to the high risk of contamination with microbes and endotoxins". The same notice reports adverse event reports after use of NAD+ injectable drugs including "severe chills, shaking, vomiting and fatigue", reactions the agency describes as consistent with excessive endotoxin levels.

That converts directly into one thing to check before any coupon is worth entering: does the batch certificate report a bacterial endotoxins result, the LAL assay, or does it stop at identity and purity by HPLC and mass spec? Ascension publishes two third-party assays for this listing, from Kovera Labs on batch 25-05260628 tested 14 June 2026 and MZ Biolabs on batch 25-01260229 tested 26 January 2026. Read the scope of the testing, not just the headline number, and match the batch code to the vial that arrives.

Two smaller notes for completeness. Nicotinamide Adenine Dinucleotide (NAD) sits in FDA category 1 of the 503A bulk substance lists, meaning under evaluation with non-enforcement while that evaluation runs, which is neither approval nor a permanent position; our regulatory page covers it properly. And the material sold at this price is labelled for laboratory research use, which is what the NAD reference page and the NAD calculator on this site are written against.
