  • Setting a New Standard for Purity: To ensure that you are getting the highest-quality l arginine and l citrulline product (not to be confused with just Citrulline malate) , each batch is tested for quality and purity both during and after manufacturing.
  • Quality, First, and Foremost: Toniiq products are produced in a GMP-certified, state-of-the-art manufacturing facility in the USA.
  • Each Batch is Individually Tested: We test each batch both ourselves and through a third-party independent laboratory to ensure our ingredients contain the correct standardised level of purity and active ingredients. We also test each batch for any possible additives, contaminants, and impurities to ensure the highest level of quality.
