An endurance MTB friend of mine described a process called 'glycaemic clamp' whereby insulin is used in conjunction with glucose to fully recharge the muscles with glycogen overnight. (normally not possible after several hard days according to him) The blood glucose is monitored (hence the strips) and the insulin doses are adjusted accordingly.
He said he know's of stage racers who've done it and insulin is undetectable. I have always taken this story with a grain of salt, but do you think it's possible?
Perhaps the syringes are being used for insulin after all... just it's not by diabetics.
Edit: Its seems I've been beaten to the punch... (by the two above... at least I have my answer! wanna sell me some insulin?? hehe)
Well, yeah insulin is undetectable. It's a natural hormone that is produced by your body anyway and there aren't measurable "insulin levels" (at least as far as I know... and I've been a diabetic for 20+ years).
I guess my problem with it is that your body produces insulin naturally. The more glucose (food) you take in... the more insulin your body produces. What people are saying insulin does is accurate... but it all happens naturally without an injection. If you eat 1000 grams of sugar and inject no insulin... your body just makes more.
The reason diabetics need to inject it is that their body doesn't make enough (or any).
Here's the problem with using it for any other purpose. When you inject insulin... your blood sugar WILL drop. This causes a lot of problems. Weakness, light headedness, trembling, passing out, etc. The only way to get it back to where it needs to be is to consume glucose (or inject or take it through an IV I suppose). But this is the same effect as just getting the glucose... because a non-diabetic taking sugar will cause their body to produce insulin.
I guess I'm struggling to see why you'd inject insulin rather then just "dope up on sugar".
*** edit *** Maybe it has something to do with how insulin is absorbed when dealing with hard exertion. My understanding deals more with normal daily life... so perhaps when you are killing yourself on a bike for 7-10 hours a day your body doesn't produce insulin in response to sugar intake in the same manner. I'll have to do some reading.
