The proteins in the amino-acids might have been responsible for the change in the hemoglobin between gorillas and humans.

No, it has never been tested in humans. If ingested would cause severe ulcers among many other serious symptoms.
Would you buy a perfume if you didn't know that it was going to definitely not have a risk of causing severe problems? If I gave you the choice of two perfumes which smelled the same, but one of them had been tested with no side effects and the other hadn't been tested at all, which would you choose? By testing perfumes(on humans, nonetheless) you make sure that there is nothing in it which is harmful to humans

Because it is believed that a human life is more important than an animal's life. People don't think of animals feeling pain, testing on humans seems worse than testing on animals. Most of the products are tested on on humans after they have been tested on animals.

Yes,I do believe you could because the H1N1 vaccination has never been tested on humans!! I myself is not getting the needle.
We are not sure. There are many ads that say "not tested on animals" or "tested on animals". We know that all make up products or anything have been tested on animals. All make up products have been tested on animals but we're not sure if they're made from animals unless you include us humans and we are technically animals since we are mammals so yes?
Synthroid is a schedule A drug which means it has been extensively tested in humans and does not appear to cause any harm to the developing fetus.
shampoo,pesticides,disease cures,cloning,toothpaste etc. all of this has been tested to see if it is safe on animals before it is sold to humans, thousands of animals have to undergo alot of pain,stress and suffering from having these products tested on them before they are aloud to be sold to consumers
