Events of Injustice: Gods Among Us
Although the pill was originally intended to be used by members of the Regime, Batman and his insurgents, including the heroes from the alternate world, also get a hold of them, thanks to Lex Luthor. Harley Quinn would later distribute the pills amongst the Joker Clan, allowing The Joker to take advantage of them as well.
According to Batman, 5-U-93-R increases the bone and tissue strength by several thousand percent. Joker further claims that anyone who uses the pill could have a bus dropped on them and not be hurt. Joker proves this by surviving multiple gunshots when Regime soldiers break into the Joker Clan's hideout.
