Yes i wouldn't start using TQs, Celox, Chest Seals etc without training.
I have all sorts in my day sack that goes pretty much everywhere with me from Pressure Bandages, Celox, Chest Seals, TQs to Nasopharyngeals and Oropharyngeals.
My over the top approach comes from my mum falling off her bike around the corner and impaling her thigh on the brake lever. Fortunately I was able to stop the bleed with nothing but elevation and direct pressure but when she got to the hospital we found she had nicked the artery and a few mm further across and I'd probably have struggled to stop it with no kit, despite having all the training.
