That's correct that for somebody with a functioning pancreas, their insulin secretion will match the requirement. If bloods begin to rise, then insulin will be secreted. The big difference though is that the life of the insulin is very short and manages blood glucose levels back down safely. I hope I explained the 'transporter' situation adequately, because it does impact on how efficient your muscles are at taking glucose out of your bloodstream. Glut4 transporters are the receptors within the muscles which facilitate the uptake of glucose into the cells. They are generally mobilised by insulin, however when you exercise, your contracting muscles cause the proliferation of numbers and additionally the transporters mobilise to the surface of your cells. Consequently insulin is no longer required for glucose uptake. Add insulin to the mix artificially and you are susceptible to very rapid glucose uptake (and corresponding rapid blood glucose fall). How you choose to manage your BGs is down to you, but I if you have a fuller understanding of how your body works you'll be able to weigh up the potential 'risks' involved.Hope I explained that ok. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
