DNA is remarkably stable. I’m not sure if it’s true, but I’ve heard reports of separating it from proteins by boiling the stuff, which will certainly destroy the proteins but apparently leaves DNA largely intact. The second it’s inside your body the enzymes in your bloodstream will start tearing it apart, but that’s also true for practically anything else you can inject. Until then, refrigeration is far more than enough.
