ATHLOCK- Banned Substance Free

Introducing ATHLOCK™ Banned Substance Free Verification by Nutrology.


ATHLOCK™ uses world class anti-doping screening on a lot-by-lot basis to ensure that products are not inadvertently contaminated with any banned substances. Athletes can feel confident that any Nutrology product containing the ATHLOCK™ logo has been screened and is safe to use.

  • Screening is performed at a ISO 17025 accredited laboratory.
  • Every lot is screened for over 150 banned substances.
  • Detection levels are measured down to nanograms (one grain of salt is equal to 55,000 nanograms).
  • Analysis is conducted using gas chromatography with mass spectrometric detection (GCMS) and liquid chromatography with mass spectrometric detection (LCMS).

Every lot is tested for the following banned substances:

1,4-androstadiene-3,17-dione2

4-androstene-3,17-dione and/or 5(6)-androstene-3,17-dione3
