I tend to think that the testosterone increase would come from absolute terror, and fleeing in panic, but OP will know that the lions roaring is only a recording. He’ll know he can stop if one of his shoes is uncomfortable, ffs. That changes the scenario a bit.
Maybe sounds that might actually happen around OP happening randomly and also realistic sounding. Like a car beeping right next to them or aggressive dogs right on their heel. Would probably only work for a bit.
