honestly it is a lot of scare tactics. the deaths from insulin usage are weird situations where a person overdoses on it and then falls asleep or something wacky like that. at proper dosages it would not be possible to die from it, if it was that simple every person who wants to commit suicide would just inject some insulin and all those diabetics out there would be dropping like flies.
now having said all that before someone gets butt hurt and thinks i am recommending insulin know that i have always advocated that no human being (unless they are type 1 diabetics who cannot produce insulin) has any business putting insulin in their bodies PERIOD. and if someone wants to debate this they can listen to my podcasts where i talked about it a zillion times
