Only a pure performance counts!

Virtuoos deliberately chooses to have every product batch approved by authorized and certified laboratories. This process starts with stringent identity and quality checks of the raw materials, thorough quality checks during the production process and meticulous final checks of the finished product. All batches comply with the standard norms of NZVT and are tested for the absence of doping related substances.

The purity of our supplements is independently tested in an appropriately qualified and certified laboratory.
