This is some info that I found which may halp you a bit....
IGF + Insulin
If you plan on doing IGF1 with Insulin, listen closely IGF1 is not that expensive, sure you can get away with using less by including insulin in the stack, but IGF1 and Insulin together have a pro-insulin effect on your blood sugar balance. It can enhance the chances of a hypoglycemic episode ten fold. I would recommend against it for any one not ABSOLUTLY comfortable with insulin or IGF1.
Here is how insulin and IGF1 work together. Igfbp3 is the binding protein, which allows IGF1 to remain active in the system for a long enough period of time to really work its magic. IGF1 by nature has a half-life of less than 10 minutes by its self. The molecule was so small it would escape the blood stream very rapidly. This was the reason IGF1 was so "underground". It took very frequent injections at high dosages to achieve even minimal results. Aside from this reconstituting the compound required a degree in biochemistry. This short acting version was the only IGF1 known until recently IGF1 would have been administered in 100 mcg dosages 4-6 times a day. That is a hell of a lot of IGF1. That explains a lot of the distended bellies. Now with R3 long chain IGF1 and the Binding protein IGFBP3 IGF1 will last up to 6 hours in the system. By binding IGF to the IGFBP3 you make the molecule larger and it gets trapped in the blood stream until the protein is broken down and the IGF molecule escapes. You can further its life by combining Insulin with it, although I here its very risky. Insulin prevents the breakdown of IGFBP3 and leaves the IGF1 molecule roaming free in the blood stream for longer periods of time up to 12 hours as insulin levels return to normal IGFBP3 will begin to break down and the IGF1 will escape from its bound protein IGFBP3 again having a half life of less than 10 minutes.
Insulin should be taken at the normal dosage it is usually administered at minus 10% about 45 minutes prior to the IGF1 infusion. Again let me remind you this can be deadly if you don't know what you are doing. And of course do not use Insulin for the nighttime injection of IGF1 by taking it in the morning you prolong the IGF1's half life to 12 hours and then take a 6 hour injection, you should be fine. Hell if you want to eat a big bowl of rice and drink another 100g of simple carbs 45 minutes before the bed time IGF1 infusion you could spike insulin for at least a few hours of extended IGF1 activity. If your not going to be using insulin in the stack then go ahead and do the same in the morning.
