Ripe bananas and oranges, for example, are mostly sucrose and glucose. I make my protein shakes with bananas + strawberries when I run out of dextrose. I still see gains. I suppose everyone is different.
Ok youve mentioned bananas twice already.... not trying to dog you but people need to check their information before they give out advice here.
Banana's are rich in FRUCTOSE, which is primarily used to fill liver glucogen, NOT muscle glycogen. For the purpose of a PWO meal, bananas are completely pointless.
