The Pharmaceutical Testing Facility is a room. "A [if the player is short]large [end if][if the player is tall]cramped [end if]white space with sterile counters and a[if the player is tall]n uncomfortable little[end if] stool. There is also a mirror, behind which someone must be watching you. But you can't see through to that."
A counter, a one-way mirror, and a stool are scenery in the Facility. The stool is an enterable supporter. The counter supports a plate.
The growth pill is a kind of thing. A growth pill is always edible. The description is usually "It is leaf-green and has a reassuring logo of a curling vine on the side. Nothing to worry about, nothing at all." Two growth pills are on the plate.
