So , being your still taking in food the pancreas is still going to respond to that and produce insulin. you pancreas does not know that you injected insulin, it simply sees blood sugars elevate and nutrients are in the digestive tract and it releases insulin.
this is actually how some guys end up going hypo. they shoot 10iu of humalog, slam a bunch of fast liquid carbs, get a spike in blood sugar, and your pancreas responds to this at the same time the humalog begins hitting you. you get both a natty and exogenous pulse of slin.
so again.. your pancreas is always going to be producing insulin for you because your always eating food. exogenous insulin does not shut the pancreas down (only starvation shuts the pancreas down)..
now sure, your panaceas is going to produce less insulin and have the burden eased a bit when using exogenous slin. but this is only because your blood sugars are on average lower when using slin (its not cause the slin itself is present in the blood stream that makes the pancreas produce less insulin, its simply that the glucose load is not as high).
hope that makes sense. I wouldn't worry too much about it. you pancreas is going to function just fine wither you use slin or not (its high dose HGH over time with no insulin use that can cause problems).. again it does not work like testosterone use making your testes atrophy (there is no negative feedback loop with slin use)
