A price per session and a price per month are not the same number

Tomas Lindqvist writes about subscription pricing and unit economics. Updated 4 September 2026.

NAD+ is quoted per session, per month, per shipment and per bottle. None of those are comparable as printed. A session at one clinic and a month of injections are only comparable once you divide the price by the milligrams it actually buys, and almost nobody in the category does that division in public — it does not flatter the expensive routes.

So: enter what you were quoted, enter what it delivers, and read the cost per milligram. Every division on this site is printed beside the number it produced, and any arithmetic this site performs is labelled as ours rather than presented as the seller’s published figure.

Work it out

What the session or the month costsIn dollars, exactly as the seller quotes it.Milligrams in one doseThe number on the vial, the bag or the bottle.How many doses that price buysAssumes 8 doses a month, which is what twice-weekly plans usually include.

Our arithmetic, not the seller’s
total milligrams100 mg × 8	800 mg
cost per 100 mg$189.00 ÷ 800 mg × 100	$23.63

cost per mg$189.00 ÷ 800 mg$0.236

The full version lives at the cost-per-milligram calculator, which carries no advertising of any kind.

What the arithmetic shows

Across the 3 placeholder rows currently loaded, the most expensive milligram costs 45.9× the cheapest — $0.349 against $0.0076. That ratio is this site’s calculation from prices read on the dates shown, not a claim any seller makes.

⛔ Every provider figure on this site today is placeholder scaffolding, not a published price. The verified roster replaces it before launch, and nothing here should be relied on until it does.
