Velocity X is a serum that can increase a speedster's speed.
It was used to stop Frida Novikov by neutralising her powers to slow things down.
Later, while Frost was hunting Millie Rawlins/Sunshine, Barry used it to give himself a temporary boost to try and help. However it quickly faded, changing his lightning to blue as well as losing his speed.
In May 2020, a copy of Godspeed arrived in Central City looking to steal the Velocity X serums from S.T.A.R. Labs. When he was locked up in Iron Heights, he revealed that he had been sent by someone who wanted access to "infinite velocity".
