Here at XCellR8, we are always looking for ways and campaigns to stop animal experiments – such as the Lethal Dose 50% test (LD50) – which are cruel, outdated and scientifically unreliable. Please support Animal Aid, in their quest to ask the government and industry to replace the LD50 tests with science made for the 2020s, not the 1920s. It’s time for better science!
