What is the cheapest NSF certified whey protein?
BulkSupplements.com Whey Protein Concentrate 80% (1 kg) is the cheapest per 25g, at $1.65 before delivery, at $49.97 a container.
6 of the 33 whey protein products we track have their exact package named in NSF's Certified for Sport database. That is a stricter test than “the brand is NSF certified”, and it is deliberately so: NSF lists package sizes against each certificate, and a size it does not name is not one it has stood behind. Each price is delivered where the retailer publishes a delivery rate and before delivery where it does not, and each row says which. 5 more whey protein packages, from Optimum Nutrition and Sports Research, are certified by Informed Choice or Informed Sport, whose listings record tested batches and no package size at all, so they cannot be ranked by the exact-package test this page applies.

Listed, but at another package
NSF lists these products, and the listing names a package other than the one we price. Very likely the same formula; not a package NSF has put its name to.

Cheapest among the 6 certified whey protein packages we have checked, not the cheapest that exists. NSF certifies whey protein from more brands than we carry, and our catalog is extended brand by brand, so a certified product we have not added yet cannot appear here however cheap it is.

Where to buy: the whey protein shortlist
The pick is the cheapest certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows. Any answer shown beside it is the cheapest under a different rule and says so on its own line; answers that cost more than the pick fold under one line until you ask for them.
How these lines are chosen
Among 33 products and 33 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of the size in the heading, priced the same way as the per-dose figure beside it. “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.

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.
