Is a bigger tub of creatine cheaper per serving?

Yes, in every case we can check. Of the 15 creatine products we track in more than one size in stock, the largest size costs the least per 5 g in all of them. The widest gap is BulkSupplements.com: its smallest size costs 5.9× as much per 5 g as its largest.

Sometimes a smaller size costs more in total, not only per serving: BulkSupplements.com's 250 g is $20.97 at BulkSupplements.com, against $19.97 for the 500 g.

The larger size is more money today, and it is only cheaper per serving if it gets used, so check the best-by date printed on the package. Each product below is priced at one store for every size, so a difference is the size and not the shop; where more than one store sells every size, we use the one whose prices were checked most recently. Sizes count as one product when the brand, the format and the product name match apart from the size.

5 g is the serving printed on almost every creatine monohydrate label. We use it as a yardstick so sizes can be priced against each other. It is not a recommendation about what to take.

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
