This form is Adrenochrome semicarbazone.
It is a fast acting, very efficient coagulant for human blood.
One use: It is issued to SpecFor members to stop bleeding in the field far from health services.
That said, Trump was likely using the MFR(?) name (Chidlern) to draw attention to trafficking and a connection to DS adrenochrome use.
Needless to say, injecting this would cause quick death as it creates a clot.
