How is it possible if you take one shot of slin post workout, for that to shut down your natural slin production, if you use a insulin such as humilin-R. How could you be shut down if the exogeneous insulin is not active in the body for 24hours???
I don't know but I would like to. Maybe it assumes you inject in the am as well. It hangs around in your system longer than you think I believe, it's just that you aren't in the "danger zone" for more than a few hours usually.
if you ingest enough carbs the carbs will burn that shit out of your system
as far as endogenos insulin shutdown i dont think you are in danger unless you are a long time abuser
if that is your question
if this is your question,,, you will not produce more insulin while the exogenic insulin is in you body because the endogenous insulin production is caused by higher levels of blood sugar
while the exogenic insulin is still there your blood sugar will be controlled by it. when its gone your natural slin production will kick in when your blood sugar levels elevate
the possibility of long term abuse causing permanent shutdown or imparement of natural insulin production is a fear that i have never seen substantiated(by study or anecdotal evidence) but the risk makes trying it not worth it
