Every batch, tested and published.
Our creatine monohydrate is one single ingredient. Nothing else. We buy it in bulk, and every batch we buy is independently tested before it goes anywhere near production. Here are the results — the actual numbers, not a badge.
99.7%
creatine monohydrate, dried basis — batch 202504-207, tested by Cawthron Institute
What we test, and why it matters
- Tested
Identity & purity assay
Confirms the powder is creatine monohydrate, and how much of it is. It’s the test that answers “is this actually what it says it is.” Ours came back at 99.7% against a specification of 98.0–102.0%.
- Tested
Loss on drying
Creatine monohydrate holds water inside its crystal structure by design — that’s what the “monohydrate” means. This test checks that water sits where it should (10.5–12.5%). Ours is 11.3%, which is how you know it’s true monohydrate rather than something blended.

Heavy metals
Creatine is a manufactured ingredient, and manufacturing is where contamination enters. This is commissioned as its own test and reports separately — the numbers land here against the same lot as soon as they do.

Standard safety screening for a powder you take every day.

Why the assay is measured “dried basis”. Creatine monohydrate is about 12% water by weight, held in the crystal itself. Testing the dried powder is how the purity of the creatine is measured without that water skewing the number — and the loss-on-drying test above confirms the water content is exactly where it should be.
Tested by Cawthron Institute, an independent New Zealand laboratory. Loss on drying follows the United States Pharmacopeia method.
