Well, first off, my general philosophy is that life is too short to wait for insulin. So my wants and expectations are already a bit higher.
I do IM and IV for speed. On the IM, I exercise the muscle, or use massage to speed it up. I use longer needles. I over-bolus to get a faster response.
So, going into the Fiasp test, I am not really one to be happy with a tiny improvement…
It isn’t life-changing. It is a little faster, but not much. Maybe a few minutes faster. The tail is about the same.
There is no downside, other than the cost. It didn’t hurt or sting or burn me, like some have reported.
So if you have $100 to spend on it, go ahead and try it. But temper your expectations. It is not the Holy Grail like some have made it out to be.
I put some comments about it on this thread.
