Desc: Maximum Tolerated Dose: Directed by Karol Orzechowski. Maximum Tolerated Dose (MTD) is the first feature-length documentary by Decipher Films. The film charts the lives of both humans and non-humans who have experienced animal testing first-hand, with hauntingly honest testimony of scientists and lab technicians who's ethics demanded they choose a different path, as well as the simultaneously heartwarming and heartbreaking stories of animals who have seen both sides of the cage. MTD aims to re-ignite the debate about animal testing by bringing these rarely-heard perspectives to the fore.
