AITJ for covertly switching my roommate's high-performance protein powder with simple flour to demonstrate that his 'gains' are purely placebo and psychological?

¿Soy el malo por cambiarle a escondidas la proteína a mi compañero de piso por harina para demostrarle que sus ganancias eran puro efecto placebo?

OP secretly replaced his roommate's expensive protein powder with flour for three weeks to win an argument about the placebo effect—and now can't understand why everyone is furious with him, even though his 'experiment' technically proved his point.

Contexto: tengo 27 años, soy biólogo de formación (doctorado en curso sobre neurociencia cognitiva, para más señas) y comparto piso en Madrid con Martín (28), que es diseñador gráfico y, desde hace un año y medio, converso devoto del acondicionamiento físico de alto rendimiento. Nos llevamos bien, en general. O nos llevábamos.
