As it has been said that the Reiss couldn't have produced the serum by themselves, it necessarilly has to be as old as the Great Titan War. Now, does it have anything to do with the war itself ? Maybe yes, maybe not. Maybe some serum was given by the Tybur family to Karl Fritz (as the hardening serum gave Eren powers similar to the Warhammer Titan, just in "less powerfull") when they made the pact. As for the "Braun serum", I have seen people talking about it, but I don't know where the "Braun" really comes from. Is it a stretch because Reiner's family name is Braun and the bottle was named "Armor" ?
