insulin for performance not mass

[crider]

have any of you ever used insulin for endurance performance (not mass).

the only difference is I want to use it to increase recovery and mabye output after use in order to biuld higher. basicly get faster.

any ideas for different ways to use it than just taking large amounts (10IU) and eating a lot... specificly timing before an event... should you taper off of it or use it less frequently so as to not affect your bosies natural recovery process.

thanks
