Harvard Medical School

Harvard medical school, outlines some of the readily available testing methods that do not involve animal cruelty. "Scientists use technologies and approaches that allow them to avoid the use of animals in experiments while still achieving their research objectives. In full replacement, scientists use alternatives such as human volunteers and human tissues and cells, as well as computer models, or established cell lines for research as alternatives to animal studies."

Cruelty Free International

According to Cruelty Free International the methods that do not involve animal torture and cruelty are commonly more effective and faster than those that do. "Non-animal methods are often cheaper, quicker and more effective. Replacing animal tests does not mean putting human patients at risk. It also does not mean halting medical progress. Instead, replacing animals used in testing will improve the quality as well as the humanity of our science."

FDA

The FDA once supported animal testing but as of 2020 they are in the works of modernizing act 2.0 which could outlaw it. "Animal testing has long been necessary for a drug to gain approval by the US Food and Drug Administration—but it may be on its way out. A new law seeks to replace some lab animal use with high-tech alternatives."

Drug Target Review

This is a statement by the Drug Target Review, "In vitro and in silico methods, 3D tissue engineering and organ-on-a-chip are some of the promising alternatives that could replace animal testing."
