hmm, I've used insulin.. never for this exact purpose.. but I am wondering, if you cut out carbs for a few days (perhaps 3)
then full body workout.. eat a complex carb meal, wait say 30 minutes and then inject 10iu and take in a shake with perhaps 200g of dextrose..
I would think your muscles would up-take the glucose at supraphysiological rates..
I haven't tested this though, but if you have some time to test this before competition it might be worth a try if no one else with experience can chime in here...
but anyway BUMP again incase anyone with experience can help out here..
