Artificial Adrenalin I was watching Sherlock Holmes - A Game of Shadows yesterday. I saw that he had developed a serum that causes a person to react like he has been injected with adrenalin. Watsons's dog fainted, I think, and the moment Holmes injected the dog with this serum, it jumped up and ran away. So my question is: Is it possible to extract adrenalin, or was it a steroid?

Yes, it is possible to extract adrenaline from the adrenal glands. This was done in 1901, a patent was filed, and it was marketed under the name Adrenalin. It is also known as epinephrine. It is synthesized nowadays for most uses.
