I've never used commercial stage blood in a show. I teach my students how to make it themselves, and they have a lot of fun with it. I never have trouble recruiting a prop crew for a show that uses blood! (Most recent experience: The Women of Lockerbie, this past school year.)
It's just a mix of red food coloring and chocolate syrup. The food coloring alone is too bright and too clear to make believable "blood," so adding a little bit of chocolate syrup darkens it and makes it opaque. A little experimenting quickly gets the proportions right.
The base differs, depending on two things. If any actors are going to have to get any of the blood into their mouths, we use clear corn syrup. That way, all of the ingredients are safe food products. On the other hand, if the blood is going to get on clothes, we use clear dishwashing liquid. That way, the moment the "blood" hits the fabric, you're essentially pre-treating the clothing for laundering afterward. The "blood" doesn't set as a hard-to-wash stain. Just wash the piece normally after the show, and it's ready for the next performance.
