Taking post #90 at face value and following it one step further.

A new needle for each injection is not fussiness. A needle blunts on first use and a blunted needle is the reason the second injection hurts more than the first.

Post #88 and I disagree about the size of the effect, not about the direction.

If you have to inject at a different time of day than usual, that is a much smaller perturbation than it feels for a weekly compound with a week-long half-life.

taper_table, post #35: The arithmetic in post #32 is right; the assumption feeding it is the part to check. Needle length matters less than angle for subcutaneous delivery in most people. A short needle at ninety degrees and a longer one at forty-five put the material in roughly the same place. Go to post

The single most common technique error described here is drawing to the wrong graduation because the barrel was read at an angle. Read it straight on, at eye level, every time.

Posted with less confidence than the sentence structure implies.
