As with the linked study, I have absolutely no doubt that any of the treated gauzes will start breaking down after an extended period. But the point of Stop the bleed, TCCC, etc., is to stop the bleeding or trauma enough to let the pros take over. Just keep them from dying long enough for the ambulance, MEDEVAC, etc. to show up and get them to a doctor or some kind of medical facility. And hopefully within minutes, not days. Though I don't remember it (treated gauze) being brought up as detrimental at all during the course I took. As for the kits and, or TQs themselves, it ended up being cheaper for me to go directly to N.A.R. and purchase through them. This is the kit I purchased https://www.narescue.com/tactical-operator-response-kit-tork.html This kit has almost everything I'll need. I'd like an extra Hy-Fin or two, and I've already got a couple Gen7 TQs and a spare Israeli bandage around in the second kit. And I HOPE it's equipment I'll NEVER have to use, but, there it is if I need it.
