I don't know what that means, but Wikipedia says that Space Science Corporation's vehicle can cary a "2,000kg / 2700kg" "delivered payload" and SpaceX's Dragon a 6,000kg "launch payload" so they win there too by more than double.
To GTO those numbers are 2400kg and 4680kg.
The "Launch Payload" of the Dragon spacecraft (6000kg) appears to be approximately the Mass to LEO of the block 2 (10450kg) minus the mass of an empty Dragon spacecraft (4200kg).
