A man has left the internet horrified after revealing he's eating raw bull testicles every day 'for science'.

There are some pretty disgusting things on the internet, but this particular video is surely up there.

A man from Florida has shocked many social media users by eating raw bull testicles in a bid to boost his testosterone. Be warned, it's not pretty:

I mean, people go to extraordinary lengths for health, but this is example is surely up there.

The now-social media star known as John first rose to fame earlier this year after announcing a plan to eat raw chicken every day for 100 days.

The Florida man managed to successfully do this without getting salmonella, so he's set his sights even higher.

Now, he's eating raw bull testicles. Yep, bull testicles...

"We are always told that organ meats, especially testicles, will take you to the next level," John wrote in a caption to a viral clip posted to his Instagram.

"How would eating the balls of a cow not make you have huge balls yourself? This is the science we are here to test. I will be eating balls and updating daily on many aspects of how I feel physically and mentally.

"I’ll update if my energy is crazy or my peepee gets larger etc."

The first video of John's crazy challenge sees him taking a knife to the animal scrotum before cutting it open and eating the testicles with his bare hands.

While doing so, blood is pouring out of the testicles, making for some incredibly unpleasant viewing.

Many have flocked to the comments section of the Instagram video, with the vast majority horrified.

"Bro tf, I felt uncomfortable watching this ngl," one person wrote while a second added: "I literally almost threw up."

Naturally, people have been sickened by John's squeemish antics. (Instagram/@rawmeatexperiment)

And a third penned: "This might be more disgusting than the raw chicken lol."

In the days since, John has continued feast on bull testicles, teaming them with a variety of different food items.

In one particular clip, John created a BLT, though this is not the typical bacon, lettuce and tomato we all know and love.

Instead, this BLT contains 'balls, lettuce, tomato' - certainly making for a completely different dining experience.

In another bizarre video, the social media star could be seen adding the testicles to a pasta with sauce.

Certainly not many people's idea of tasty...
