What are some adrenaline pumping activities?

How can I build a Stamina/Adrenaline pill that can be used to help with physical activities?

• I would like to know how to design one used for that purpose. I got the idea from a friend, who said that he had adrenaline pumping when he was cut and there was no pain. I want to build this pill and enhance the physical capabilitys of the Human body. Any helpful feedback will be appreciated. Thank you.

• Answer:

  While a stamina/adrenaline pill sounds like a neat idea, the short answer is that it's just not possible. Injectable adrenaline (epinephrine) is already available by prescription and is used to treat life threatening anaphylaxis in persons highly allergic to certain substances (eg, peanuts, shellfish and beestings) At times, adrenaline injections can be very useful medically and even life saving. Adrenaline can be extremely dangerous if too much is given. It can only be safely used under the supervision of a physician, and even then it is only used in life threatening emergencies. It also isn't possible to package adrenaline in a pill form.
