These facilities were pitched to help further the development of mankind’s health, sciences, and technological advancements. There were many facilities around the world, with each area dedicating their scientists to the cause. Over time, of course, the way of achieving these goals became unethical and inhumane.

the experiments and the experimented on would vary

There would be hybrid animals for better companions and guard animals, trying to do the impossible (living liquid, artificial intelligence, nanites, animal hybrids, human hybrids, cyborgs, hodgepodge manmade dragons, etc), intelligence testing, strength boosters/steroid testing (some of the ones tested for strength are bought out by fighting rings and pit against eachother to see in action which serums have stronger effects and all that and in return the scientists get paid with the earnings to keep the funds going)
