How to use this list
This page is an index, not a ranking: labs are listed alphabetically and no position is for sale. To narrow the list, filter the CRO search by service, species, GLP and AAALAC status and location, or browse by study area and country using the links on this page.
Which are the best in vivo CROs?
There isn’t a single best in vivo CRO; there is the best lab for a particular study. The right partner depends on the species and model you need, whether the work must be GLP, how specialized the route or procedure is, where the lab is, and how soon it can start. Large full-service organizations suit standard IND-enabling packages. Specialist labs are often stronger for surgical models, CNS delivery routes and unusual species. Shortlist three or four labs, ask each the same technical questions, and request recent control data before you compare prices. Our CRO selection guide lists the questions to ask, and the preclinical outsourcing guide covers how biotechs run programs across several CROs.
Who is included?
The directory covers contract research organizations offering preclinical and nonclinical services: in vivo pharmacology and disease models, toxicology and safety pharmacology, DMPK and bioanalysis, pathology, surgical and device models, and discovery biology. Clinical-trial CROs are outside its scope. Profiles marked Verified have been confirmed with the lab; unverified profiles are compiled from public information and may be incomplete. If you run a preclinical lab that is not listed, add your CRO.
