True, but I don't think the OP is aware of the age of the thread or other posts.
BTW, one thing to be careful of with the "Quik Clot" is that it generates a fair amount of heat IIRC.
In terms of treatment, compression bandages (ace bandages) are also very useful in treating bleeders, as is elevation. I would avoid the injections, unless you have the medical training to do it properly, since you can make the situation worse.
