I think you're confusing pain and injury. Adrenaline doesn't give things resistance to actual injury, it just gives them full access to their muscles (most of the time, we only have access to less than half of the full strength of our muscles, because full strength can dislocate and otherwise damage our joints) and lowers sensitivity to pain (partially to mitigate the pain caused by said joint injuries, partially to mitigate the pain of whatever situation caused the adrenaline to start flowing). It also raises the heart rate to provide more oxygen to the empowered muscles.

If anything, creatures experiencing adrenaline are more likely to get severely injured or killed if they don't immediately escape danger, since they won't notice the severity of their injuries until the adrenaline wears off and won't react to their condition accordingly. Adrenaline won't make it any more difficult for bullets, claws, toxins, or blades to tear through your body, you're just less likely to notice until it's too late. It anything, your wounds will be more severe, since your increased bloodflow will make you bleed out faster, or spread toxins to vital organs faster. And you'll move faster, because your leg muscles are working at full capacity, instead of ~30% capacity.

Think about the distinction between pain and injury this way: if you're paralyzed below the waist, you should still go to the hospital if your leg gets chopped off, even though you won't any pain.
