This follows the opening post rather than contradicting it.

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.

Air in the syringe is a much smaller problem subcutaneously than the anxiety about it suggests, and it is still worth expelling because the bubble occupies volume you meant to be liquid.

I have changed my mind on this once already, so take it as current rather than settled.

Post #5 describes the usual case. This is about the unusual one.

Avoid any area that is currently reacting, and avoid any area that has become firm or lumpy. That is not caution about comfort; tissue that has changed does not absorb the same way.

If that reads as pedantic, it is, and it has saved me twice.

Nothing to add on the substance. Thank you for taking the question at face value.

r.bruun, post #14: 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. Two sources, same conclusion, and I could not rule out that one copied the other. Go to post

Noted, and I have changed what I was going to do on the strength of it.

The confident version of this sentence would be wrong, so here is the hedged one.

A site rotation scheme that actually works: abdomen, outer thigh, back of arm, outer hip. Rotate through them in order, move a minimum 2 cm between consecutive sites, note the site with each dose. If a local reaction appears you have the history. If you rotate properly you will not get lipohypertrophy from overuse of one area.

A modest claim, modestly supported.

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.

Adding a source would improve this post and I do not have one to hand.
