Go for Syringe

You pick up the syringe and lunge at Alex, your arm outstretched. She dodges the first blow, as well as the second. The third blow is stopped by her hand. She grabbed your wrist, and caught your hand just before the needle hit her face. You can't move your hand an inch. Your other hand is grabbed by Alex's free hand, and you're pulled around, your back facing Alex.

"I'll admit, you came pretty close there." She says. "But I'm afraid that's going to cost you in the long run."

And with that, you feel your arm bent back forwards again, the needle headed straight into your right thigh. Ten seconds, and you're out on the floor cold.
