17-Phenylandrostenol (17-PA), or (3α,5α)-17-phenylandrost-16-en-3-ol, is a steroid drug which binds to GABA_A receptors. It acts as an antagonist against the sedative effects of neuroactive steroids, but has little effect when administered by itself, and does not block the effects of benzodiazepines or barbiturates.[1][2]

gollark: Also, lend us your CB silvers!

gollark: Plot twist: DC is just a testing ground for TJ09's desire sensor system.

gollark: Then when you want a mint or something it's all chronos.

gollark: Basically, see, the cave senses your intention. If you want to catch, say, chrono xenowyrms, no chronos spawn.
