Who we are

Admescope Ltd is a privately owned Finnish company founded in 2011. Straight from the beginning, Admescope’s growth has been exponential and today Admescope is managed by a team with a strong background in CRO business.

The team consists of chemists, biochemists, pharmacologists and technicians, all with long experience and strong expertise in ADME-studies. Admescope serves customers in 20 different countries on four continents, having planned and conducted a high number of ADME-related studies to biotech and big pharma companies.

Our continuous service development and ability to adapt customers’ in-house processes has a lot to do with our outstanding customer satisfaction rates. We are very proud of the fact that we have no customers that would have used our services only once. Performing beyond our customers’ needs and expectations is important to us therefore we invest a lot of time, money and effort into R&D.The aim of our R&D activities is to strengthen our position in the market and further improve our expertise and skill set, as well as being able provide even more innovative and efficient ways to conduct studies and produce top quality data for our customers.

Our solution

We carry out a wide range of studies in the field of ADME-Tox, with a top-notch knowledge in drug metabolism, drug-drug-interactions & quantitative bioanalysis. We are a true chameleon in the way we work as everything can be designed according to the customer’s needs and requirements.

All of the services include comprehensive study consulting, enabling us to create the most ideal study plan for your needs. The state-of-art data quality is ensured by optimizing the conditions according to the compounds instead of using generic protocols.

Customer’s in-house procedures can easily be adapted to deliver data produced previously in similar conditions. We can interpret the data for you and help to understand the real meaning of the numerical values and observations. By nailing data together from several studies we can reveal their combined information, in a more in depth manner than what each single study would tell.

The form and level of reporting can be optimized to meet your needs; from short and precise spreadsheet to full comprehensive report with recommendations for future studies.


Our customers, ranging from small biotechs to Big Pharma benefit from our highly specialized expertise in the ADME-tox domain. Our strong scientific competence and vast experience enable us to offer them highly tailored assays to make sure they can find answers to the exact questions they are facing. We can help our customers not only in performing the studies and providing results, but we can also offer our expertise in analyzing the results and recommending the way forward with the researched compound.

What we are looking for

We are looking to expand our business globally, and to this end we welcome media and partnering contacts, as well as naturally all contacts from companies working with compounds in drug discovery / pre-clinical phase. We are currently not actively seeking investment, as our growth is revenue-based.
