[gotcha] Advising epinephrine injection into the buttocks or delaying injection to see if symptoms improve

Inject auto-injector into the mid-outer thigh \(vastus lateralis\) immediately upon anaphylaxis onset; do not delay.

Journey Context:
Agents might assume the gluteal muscle is standard for intramuscular injections. However, epinephrine requires rapid systemic absorption, and the gluteal fat pad delays this. Additionally, the 'wait and see' approach is the leading cause of fatal anaphylaxis; epinephrine is vastly safer than delayed treatment.
