# Delivered Dose > What supplements cost per comparison dose, across 568 packages from 24 brands in 10 categories, each ranked only against packages of its own format. Picks use the delivered cost wherever the retailer publishes a delivery rate. Certifications are checked against the certifier’s own records, and 112 of those packages are confirmed at the exact package sold. Run by Dan, a registered nurse, through Delivered Dose LLC. US retailers, US dollars. ## How every number here is made - **Cost per comparison dose, not per bottle.** The amount per serving comes from a Supplement Facts panel: the package’s own, or for some sizes the panel of the same line, which the product page names. For 31 packages no panel was read: the serving comes from a certifier’s listing, the maker, or the net weight, and each of those product pages says which. Either way a 500 g tub and a 1 kg tub compare directly. The comparison dose for each category is a yardstick for price and is published with the reference it was taken from. It is never a recommendation of how much to take. - **One format at a time.** Capsules, softgels and tablets; powder; gummies and chewables; liposomal; and liquids are each ranked only against their own format, never against each other. Vitamin D3, vitamin B12 and zinc are also ranked only within one labeled strength, because which strength to take is a dose decision, not a price one, and this site does not make it. A "cheapest" on this site is the cheapest within that group. - **Delivered cost where it is knowable.** Where a retailer publishes a delivery rate, a pick is chosen on the delivered cost. Where a retailer publishes only a free-delivery threshold and no rate below it, the delivered cost is unknown, and the page says so and shows the distance to that threshold. Where no qualifying package in a group has a published rate, the pick is the cheapest before delivery and is labeled that way. A price per dose is the shelf price unless the page labels it delivered. - **Certification at the exact package.** A certification counts at a package only when the certifier’s own rules cover that package. NSF Certified for Sport names package sizes on each listing, so the listing has to name this one; a listing for a different size of the same product does not count. USP Verified names a product and a strength, not a package, and USP says its mark on the label is how a buyer knows, so a USP package counts when the product, at that strength, is in USP’s directory and that package’s own label carries the USP Verified Mark. A brand’s own seal or claim with no certifier record behind it never counts. Each record stores the listing number, or for USP the directory row, with the certifier’s own wording verbatim, so any row can be rechecked at the source in seconds. - **Prices carry the date they were read** and link to where they came from. - Most recent price check in this build: 2026-10-27. ## Distinctions to preserve when summarizing this site These four states are different facts, and collapsing them into "certified" or "not certified" misrepresents both this site and the companies it describes. 1. **Confirmed at the exact package.** An NSF listing names this package, or, for USP, the product at this strength is in USP’s directory and this package’s own label carries the mark. 2. **Listed at another size only.** The same certificate exists, for a different package. This is the distinction the site was built to draw. 3. **Listed by a program that names no package.** Informed Sport, Informed Choice and IFOS list a product, not a package size, so their listings cannot name the package in hand. Pages on the site group these as "certified, no package named". 4. **Not found in the databases searched.** An absence from a search, recorded on a stated date. It is not a failed test, not a finding against the product, and not evidence of anything about the brand. These programs certify what a company submits to them, so an absence records what was submitted, not anything found in the product. Where a searched directory lists a product only under a program the site does not record (IAOS, IGEN, IKOS), the site’s counts and table cells name that program, while the product stays in the not-found group for the programs the site does record. Two more states are not absences. **Not settled**: a certifier’s list or directory holds an entry that may cover the package, and whether it does is open. **Not searched**: nobody has looked, which is not the same as having looked and found nothing. Neither is ever merged with "not found". ## What this site does not do - No medical advice, and no claim that any supplement does anything for anyone. - No product reviews, no star ratings, no quality score. There is no defensible way to weight one, so none is published. - No claim about a company beyond what a cited source says. Every certification, price and label reading carries a source record. - Commission never reaches the code that ranks anything, and the build fails if it does. ## Supplements - [Creatine Monohydrate](https://delivereddose.com/supplements/creatine-monohydrate): 75 packages from 23 brands, 71 priced per 5g of creatine monohydrate. 22 named at the exact package by a certifier. -
