Is Optimum Nutrition creatine third party tested?
Partly. Informed Choice lists some of the Optimum Nutrition creatine we track. We also searched NSF Certified for Sport, USP Verified and Informed Sport and found no listing.
Informed Choice lists tested batches and records no package size, so there is no size question to answer there. Informed Sport is a separate program; under this brand it lists a product sold only in Europe, not this tub.

A missing listing is an absence in a database, not a failed test. Most supplements have never been submitted to any of these programs.

Where to buy: the creatine monohydrate 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 61 products and 74 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 “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.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.
