>You need to chemically analyze your product, and ultimately you need to try it on people. I can think of many industrial applications where biotech could help without the need to test it on humans, eg. food synthesis - efficiently producing essential amino acids, carbs and fats by bacteria in an environment suitable to industrial production. Or materials like that spider silk they did when genetically modifying silkworm.
