Myself, I learned personal method of insulin use from Oliver Starr, as of some findings he had had perhaps six or eight years ago. One of his interesting findings is that insulin use does NOT have to figured based on carbs, as high protein can also serve. So he had a protocol in which 4 IU was used 3x/day, himself stepping up from that but acquiring insulin resistance when doing so (which however was reversible.)
My own findings and that of some others that have gotten back to me on their findings has been that when the total dose per day is only 12 IU or so, there has been no detectable impairment of insulin sensitivity. Of course, a given individual might be an exception.
Also with time I took to, where carb intake was high, simply making this a single daily dose of 12 IU, assuming it was a workout day and with quite high intake of carbs and protein post workout. Absolutely one should not jump to such a dosage. This also did not lead to any loss of insulin sensitivity.
In terms of being hard on the body, I don’t think it is, because it does nothing bad to blood sugar and if anything the load on the pancreas is reduced.
It’s true that provided one is ABSOLUTELY diligent about not going to sleep post-injection, and eats frequently (every 2 or 3 hours) as one should do anyway, and the food intake is properly planned, and no mistake is made in the dosing that one isn’t going to go hypo or die or whatever. However, all that is a lot to assume, too much I think, to expect to every single time prove true for every single individual given say 1000 or 10,000 people reading it. We can all make mistakes, and a mistake with this can be grave. Accordingly it is properly, I think, called a high-risk approach. It can be safe for an individual, but I think not safe for every single one of a large number of individuals – and sometimes one never knows who it is that’s going to make the mistake, it might be oneself.
Well, suppose that there are other drugs one injects with an insulin needle, say HCG or GH. One is used to using say the 30 IU mark for the GH, the 50 IU mark for the HCG, or what have you.
Enter brain fade, and instead of the planned 12 IU (or whatever) of insulin, one draws 30 or 50 IU and thinks it correct, on account of being so familiar with that value and just having a moment of thinking wrongly.
Or, sometime in one’s life, just being bone tired post workout and dropping off to sleep and getting only the first meal, not the followups needed after the injection.
