And you previously said muscle glycogen is useless in terms of low BG because it can not be transported but rather can only be used in the specific muscle it is stored in - yes? How much does one gram of glycogen raise BG? Or is there a glycogen to carb equivalence factor? ---

Yes, muscle glycogen will not raise your BG. It is only used by that particular muscle. It is not “shared” The translation from glycogen to carbs is equivalent, 4 calories = 1 gram of carbs or glycogen. The only weird thing about the glycogen conversion is that each gram of glycogen has 3-4 grams of water bound to it. But you can consider them the same. ---

So if we have ISF of 40 and I:C of 8 which translates backwards to 8 carbs raises BG by 40 points multiplied by ~ 100 grams of glycogen then we could estimate to be able to get about 400 BG points from one fully stocked liver? ---

Maybe my math is off, but I get 500 points from those numbers. 8 is to 40 as 100 is to 500 ---

Yerp. Your math is better. 😬 And thanks for the liver mini-lesson !!! ---

Thank you guys for following us. We are still in the development cycle and are working hard to raise capital to get this device to market. We got a patent and are now working on a design that is smaller than Insulet’s Podd but also includes a glucagon pump and integrated sensor. Jerry co-founder & CEO Pancreum, Inc. ---

I know someone :guinea_pig: who would love to test it for you. 😉 [Previous page](https://forum.fudiabetes.org/t/the-great-insulin-glucagon-dual-pump-experiment/2273.md?page=1)
