We are a CRO integrated by a professional and multidisciplinary team that will guarantee reliable results

At T&T, we are involved in the dissemination of statistics applied to animal production and consolidated as one of the most specialized CRO’s (Contract Research Organisation) full service within the sector.

  From June 2022, T&T is part of Tentamus Group (Internationl Group of specialized laboratories). This allows us to have sinergies  and collaboration agreements with universities, research centers and industry experts, increasing our potential in terms of process improvement and innovation.  Our excellent relations with the international veterinary pharmaceutical industry and animal feed additive producers have enabled us to find a niche in this business: the execution of field trials that verify the safety, effectiveness and quality of veterinary products. 

Our offices are located in Monzón (Huesca). This creates a strategic geographical ubication due to the proximity to the animal farms where we perform the trials. Our investigators have the maximum control of the processes.

Accuracy and precision are the principles that have guided T&T since its foundation. Alberto Morillo, founder of Tests & Trials, began to work in the field of clinical trials with animals in 1998 and two years later, this adventure started until now.

T&T also offers services in statistical data for all type of industry.
