Talk about an adrenaline rush
In a crazy “experiment” former UFC fighter Houston Alexander was injected with enough adrenaline to kick start a heart in cardiac arrest – to see what kind of damage he could inflict.
The footage, shared on TikTok by TV show Sport Science, shows the 50-year-old having 0.6 milligrams of adrenaline injected into his body – before using his newfound energy to fight a dummy.
In the first of the two videos, Alexander is laid out on a table while a doctor injects him in the thigh with an “extremely potent” dosage of adrenaline.
Alexander then jumps to his feet and begins to batter what appears to be a crash test dummy in the face.

A commentator explains: “Dr Isaac decides to proceed with [the] injection. A total dosage of .6 milligrams is extremely potent, as much as an emergency room doctor might give a patient suffering cardiac arrest.
“It doesn’t take long for the epinephrine to saturate the bloodstream, sending Houston’s heart rate skyrocketing to 155 BPM.”
Doctor Isaac then states: “Blood pressure response 156 over 90. Heart rate response has increased, epinephrine response is present.”
Following this, he asks Alexander: “How do you feel?” to which he replies: “I feel it run into my veins.”
On the original video, which was posted on YouTube in 2014, the caption reads: “This MMA fighter sees the difference in his performance from creating his own adrenaline through emotion and being given a high dose of adrenaline.”
In the first instance, Alexander unleashes on the dummy, relying on nothing more than the “inspirational” words of his coach Mike Doyle, who was attempting to help him produce as much natural adrenaline as possible.
Doyle told Alexander: “I want all that rage you experienced when you lost and all the disappointment.”
After hearing this, the former UFC star was able to generate 1,000lbs of force – considerably more than the 900lbs of force he produced after his body was injected with synthetic adrenaline.
What is an adrenaline rush?
According to WebMD, an adrenalin rush works on the “quick breakdown of energy in your body. Your body breaks down sugar in your liver”.
This, the website explains, “helps give your body quick, long-lasting energy during a stressful situation”.
“When your body releases the stress hormone, epinephrine, it triggers the release of a second molecule. This molecule, cyclic AMP (cAMP), plays a large role in regulating metabolism.
“The molecule cAMP also acts as an intermediary for certain hormones.
“An adrenaline rush is caused by hormonal changes. The excessive release of epinephrine can be harmful for your body. It can also give you a good feeling that causes you to want to seek out another adrenaline rush.”
