Eurofins tests find no quantifiable impurities in three Pürest Creatine lots
In comparative testing by Eurofins, three separate production lots of Pürest CreatineTM were evaluated alongside a premium creatine described as an industry purity benchmark. In all three lots, dicyandiamide (DCD), dihydrotriazine (DHT) and creatinine fell below the laboratory's limits of quantification.
The benchmark sample contained measurable levels of both DCD and creatinine. DHT stayed below the quantification limit in both products. Mérieux NutriSciences has also tested Pürest CreatineTM for creatine manufacturing impurities.
