However, i think the length of time a site can go before it gets occluded with gunk from the immune system is anywhere from 1 to 7 days for different people. Theoretically at least, then, there are people who can use a site for 6 days without a decrease in insulin in the short-term. In the long term though I think they’re still setting themselves up for scar tissue and fat accumulations that will reduce insulin absorption. Pers…
