Well depends on how high up is the injury but direct pressure with blood absobing bandage and tilting the entire body would help. Yes in this case the quick clot would be something to have. Also unless the wound is above the creese of your tight you can always find a pressure point.
I think it is a great product but even their instructions state that it may not work for high pressure wounds. I saw it being used and it works, one of the volunteer agencies in my town used it on the calf injury. Doc in the ER had a heart attack later on when he needed to clean stuff out and he didn't understant the way it worked. And think about this you got aorta with first branch being coronary, than renal, some abd stuff and femoral. We are talking some high pressure stuff here especially if the victim was active right before the injury happened (since every body system shots down to keep maximum blood flow for oxygenation). Also with small deep wounds quick clot may not be able to reach deep enough. So you stoped all the bleeding on the outside but you still have internal bleed. But sometimes it is still better than nothing.
I also saw smaller packs of their products on BQ website.
Now what really gets me is that according to quikclot website they have 100 % survivability and 0% mortality rate.
