What is LD50 Testing?
The company that sells the majority of Botox Cosmetic in the United States is Allergan, Inc. In the documents it filed with the United States Food and Drug Administration Allergan, Inc. states that every batch of Botox Cosmetic is tested using the LD50 method before shipment. The LD50 test is performed by injecting 100 mice with the Botox Cosmetic. If more than 50 of the mice die, then the batch is ready to be shipped. All of the mice suffer the paralyzing effects of botulism poisoning; they slowly suffocate as their muscles become unusable. It can take four days for the mice to slowly suffocate and die. In 2008, this is what the FDA and Allergan, Inc. call potency testing.
