I can't say always, but very often it is. I read an article about this a while back. Turns out that when you're exerting and hot and sweaty like these guys, a tiny cut in the right place, like on the forehead at the hairline, will produce a scary looking, but inconsequential, stream of blood, with no significant pain or risk. Some people's body chemistry makes them really good bleeders. So they do very often have with them the means of making the cut at the right dramatic moment. The wrestlers are essentially stuntmen. What they're doing is difficult, physically demanding, and dangerous, even if the risks are controlled and the fights are mostly optical illusions. Pain and blood are a fact of life for them, and they take it in stride, as a pro football player would.

the answer lies in simple grossery store props. chicken intestints filled with corn syrup and food coloring (red) then tied. makes for a bloody day and easily consealed behind a palm.

It is real. A lot of people have a hard time accepting that just because the storylines are scripted, that doesn't mean everything about professional wrestling is fake. The only false things are a) the storylines are known in advance and b) the wrestlers do not actually attempt to hurt each other in the ring, they instead work together to create painful looking moves in the safest possible way while still making them look dramatic. But the blood is real, the risks are real (as they say in the commercials!) and many wrestlers spend their careers in constant pain, wrestling through injuries sustained in the ring, and it is terribly disrespectful of people to constantly accuse them of being "fakes". Nobody complains that their favorite soap operas are "fake" because the characters are fictional and the plot is scripted; yet pro wrestling is the same thing, a soap opera, set in an athletic environment... but people treat it totally differently and disrespect a bunch of guys (and girls) who put themselves in harm's way every week to entertain the public by doing down what they do. I have yet to figure out the reasons why... Sorry if that ranted its way off-topic a little, but I'm sick of that stupid "everything is fake" attitude and WilliamKidd's answer set me off! The blood is 100% real, sometimes it is produced accidentally and sometimes it is produced for effect as jalex described, but it always comes from the body of one of the wrestlers.

its real,after the wrestlers are hit by a weapon or sumthing the ref go checks with him and asked if hes ok,then the ref will give the wrestler a blade(smiliar) to a shaver and he will cut himself

its pigs blood

Ya the blood in wrestling is real.I would say that beacause I am the Undertaker From Smackdown.My real name is Mark Callway.Bsicly,ya the blood in wrestling is real.No I wont say that to keep the secret.No theres no darg-on-secret about the wwe.The blood in wrestling is real.The concept is,ohh maybe some guy came out of no-where with a chair.Hits him.That chair,has something on it,and its the razor.So,it hits the guy,the person who is getting hit will put his/her hand up,and then rip that razor from the chair.Take the razor,stik in your head,badabeam-badamoom,quik and easy your bleeding.Also its know that wrestlers are know to take asprin before there mach to enjoy it.NO.We do not use asprin.And if you were born in the 80s,there was and interview that the wwf,now changing into the wwe,Vince Mc.Mahon edmited that wrestling is now changed into entertainment,for 2 reasons,and 2 reasons only.One is that,its scripted to keep lower amount on taxes.Another is that to many wrestlers are using anabolic steroids and its killing them like 1,2,3.Thats why it was chnged to the world wrestling entertainment.To entertain you people,and also get higher ratings.Now me,I edmit some of my moves are kinda ridicoulus beacause if you look closely,you will call me a dick head.LOL.Anyway,when i want to exercute a tombstone or whatever shit you call that,I make sure that the presure of that guy is not to much.When i put him upside-down,I make sure that his head is not anywhere belo my kness.Why,beacause,I dont want to get myself sued for something I did not intend to do.Alright so when i tombstone him,and if the scenario is that he need to bleed,I take the razor out of my balls or something,and i take it out and cut him.So thats how to do something that looks seroiusly dangerous,but its not.Thank You for your time,got to go register for a hotel.All of them are booked.Bye,Bye,ohh,and remeber to be waching either raw,ecw,smakdown,we need more ratings.TNA sucks trust me,those dumb ass announcers read from script.Jim Ross,Jerry Lawler,JBL,Micheal cole,TAZZ,and Joey Styles are the reeal thing.TNA is the most fakest shit ever

in most cases it is real guys like Ric Flair who is diabetic do not legit bleed because that could be dangerous

the blood is fake all of it is fake chir table fire table lader steel cage i see it when i go ther it is easy

Some of the blood is not fake. A revealing book on this subject was written by former WWE star Mick Foley (Cactus Jack, Mankind, Dude LOve) I encourage you to read it. Not all of Wrestling and what you see is fake. For example most matches are staged with outcomes pre-determined but there is a term used in the biz called "Shooting" When you shoot a match it is very real.

`it is food coloring becase blood is darker you can see that

Yes. They cut themselves with tiny razorblades. It's called "getting color."

Yes it's real. Also to make the blood flow better they take asprin before the match which thins the blood.

it is real blood, it can depend in the particular wrestler if they can produce blood naturally or using the 'blading'. http://en.wikipedia.org/wiki/Blading_%28professional_wrestling%29

Yes despite what some people think the blood is infact REAL. I have ignorant people at my school come up to me everyday and tell me it's fake when I know it isn't.

The blood is all very real, in fact some times they cut too deep and had to get hospitalization. E.g. Mass Transit Incident, it is called "blading" or "juicing." Source: http://en.wikipedia.org/wiki/Blading_(professional_wrestling)
