Reports from CUP Laboratorien Dr. Freitag GmbH are based on a verified legal entity, a confirmed physical address in Radeberg, and named leadership with documented tenure.
- Dr. Dirk Freitag-Stechl has served as Managing Director since 2008 and holds a PhD in chemistry.
- The company is registered at Amtsgericht Dresden under HRB 24247, with commercial register data listing incorporation on 14 November 2005 and a stated founding year of 1991.
- The lab publicly offers radiochemical purity analysis, radiochemical yield determination, and radiolabelling of active substances including peptides, with determination of assay and impurities.
These are concrete, checkable facts. The rating remains 'Listed' rather than 'Substantiated' because the public evidence does not yet converge far enough for a level-1 statement: no independent evidence of current analytical performance for the relevant method and matrix was found, and no public laboratory-controlled report verification route exists. These are neutral limits on how far this public review can go, not negative findings.
DIN EN ISO/IEC 17025 and GMP accreditation are each claimed but could not be verified in an accreditation body's own register; the claims can neither be confirmed nor refuted.
No community, forum, or independent scientific references evaluating the lab's analytical quality were found. No concrete open concern was identified. These are signals, not a verdict.
