Question: I have both the old and the new sport quick-clot paks. I have read the old system causes burns and the newer type is safer. I also have the combat gause roll [I presume the QuickClot combat gauze–Grouch] that is to be packed into a wound. Can you give a quick-post on the correct application of those products for us?
There is indeed a difference between “old” (before 2009) and “new” (current) QuickClot.
The old stuff was a powder, which was poured into the wound, and set up an exothermic reaction that could cause burns, etc; it also hardened, making it both more effective, and harder to deal with once you arrived at the hospital.
The new stuff uses a different formulation, and is attached to gauze, making application and removal easier.
The company cites clinical studies here.
Some love, some hate, some have had the company come back to try and correct them.
Please see the accompanying video; it looks like it works. And can work well. Warning: lots of blood, and a real animal is cut to test the product:

I would only add that you should not view QuickClot as magic, despite the title of this blog. Rely first on pressure, then tourniquet, then QuickClot as backup.
