[DBZ] When did Goku & Vegeta learn how to go SS Blue?

In battle of the gods they were just Super Saiyan God then in Resurrection F they were able to turn SS God SS (or Blue) when did they learn to make this transition?

SSGSS (Super Saiyan God Super Saiyan) is just a regular Super Saiyan transformation after tapping into God powers.

Basically, after you become Super Saiyan God, then you lose your Full God powers, you do retain some of the power. Going Super Saiyan once you have reached SSG before automatically gives you SSGSS. It's not a new transformation, just a more powerful version that comes with blue hair.


It's worth noting that Super Saiyan God isn't a Super Saiyan stage. It's a boost to *base* power. It makes the user more powerful temporarily and some of the power is permanant. It's more akin to Kaioken than Super Saiyan, really.
