We provide worldwide registrations and continually address the need to subcontract GLP-studies to contract laboratories. Our work greatly depends on receiving quality data extracted from GLP-studies. It is critical that we collaborate with trusted reliable quality labs. Our strategy is to build long-term relationships and to integrate them into our partner network. The world of chemical regulatory requirements is constantly growing and getting more complex.

We will not be able to set up subsidiaries in every country worldwide but we will share and exchange valuable information with our partners globally.
