My experience with Quick Clot in Iraq leads me to caution folks to be careful ... don't put the package in your mouth and tear it with your teeth. Don't rip it open as hard as you can, and spray it into eyes, nose, throat, etc. Use your EMT shears - be quick, but purposeful. It will work in conjunction with direct pressure, tourniquets, etc. I keep it in my trauma kit.
Can I say too, make sure you are treating the bleeder, and not the leaker. Alot of folks leap to the first sight of blood, and fail to do a full body check. No point dumping QC on the seeping entry wound, if its spraying out the other side.
Re: urine for cleaning a wound, and while I'm at it, tourniquets. What goes for trauma care in suburban America is based on the strong likelihood of an ambulance and an ER visit within hours. Survival/Combat trauma care plays by different rules, and there are often long term effects (like secondary infections) that an EMT or ER Tech would try to prevent. Settle in your mind that you're going to save a life first, then treat for infection later if necessary, and you'll be okay.
