2 cans of BG 44K PlatinumQ

I drive a 2010 Chevrolet Avalanche with a 5.3 liter engine. Will this be safe for it.

how often should I use this 44K fuel injector cleaner?

The pictures show 2 different cans. one has just the gdi label & the othe has both the gdi & the gdf label. which is it?

Will This Work In A Fuel Injection Service Tool? Will The Engine Run On Pure BG 44K 208? Or Does It Need To Be Mixed With Gasoline?
