It seems a drug known as Oxytocin helps reduce shyness and helps people with social anxieties better fit into social situations. It's now in a nasal spray form.
Any college student can tell you this is nothing special. There's a much better solution that has the same effect and is able to be ingested in liquid form. It works wonderfully to help people shed their shyness and fit into social situations. Alcohol is special like that.
