Do you need GMP material for GLP studies?

Yes, in most cases GMP-grade material is recommended — and sometimes required — for GLP studies, especially if the study data will be used to support a regulatory submission (for example, IND or CTA). GMP (Good Manufacturing Practice) ensures that materials such as active pharmaceutical ingredients, reagents, or biological samples are consistently produced and controlled to meet quality standards. Using GMP-compliant material in GLP (Good Laboratory Practice) environments helps guarantee data reliability, traceability, and reproducibility. However, for early preclinical or exploratory studies that are not intended for regulatory purposes, non-GMP material can be acceptable. In regulated environments, a GLP study typically tests the safety or performance of a product made under GMP. Therefore, integrating both GMP and GLP principles ensures compliance, credibility, and smooth transition toward clinical testing and commercialization.
