Subcutaneous administration as a route: absorption kinetics from abdomen versus thigh versus upper arm, tissue depth, and why site rotation matters more for tolerability than for pharmacokinetics.
Four days ago I injected into the left side of my abdomen. Within an hour there was a coin-sized red area, slightly raised, and it itched. It is now day four: the…
Two related questions I cannot get straight answers to. First, site rotation. Everyone says rotate, nobody says on what evidence or at what spacing. I have seen "2…
I have kept a symptom diary against dose dates, which turns out to have been the useful thing. The figures are clear enough; the question is what they mean and what…
I keep a written log of every draw with date, volume and syringe type. I understand the observation; what I do not understand is the mechanism behind it. I have read…
I have photographs before and after reconstitution if the visual detail matters. I keep seeing this stated as a fact with no explanation attached, and unexplained…
My setup is a refrigerator with a logger and a small work area I wipe down, nothing more. I want to know whether this is a real physical effect or an artefact of how…

I keep a written log of every draw with date, volume and syringe type. I suspect the usual explanation for this is wrong, or at least incomplete. I am aware this may…
