Fructose is an insulin-independent monosachharide. This means that it converts into glucose and is stored without the action of insulin (or, at least, insignificant amounts). Fructose doesn't cause a large rise in blood sugar and, consequently, won't raise insulin levels. In short, you won't crash, and energy levels should remain on an even keel
In fact, I'd go so far as to say that they're beneficial to your bodybuilding efforts. For example, there's research supporting fructose's protein-sparing effects. The study showed that fructose spared protein while keeping blood sugar levels about the same. It was hypothesized that this occurred because of increased protein synthesis.
