Lowest power on STM32F105RC

I'm developing with an STM32F105.
On datasheet, lowest power is on StandBY mode, and it consumes about 4uA, however I get about 300uA, and I don't know what I'm doing wrong.
On my program, it is all what I do:

    gpios_init();    //All gpios as analog input
    systick_init();  //Systick to 1000 ticks per second.
    Sleep(5000);   //Sleep 5 seconds to restart and program.

Is it starting-up with any peripheral running?
How can I get the lowest consumption?
