Abt switch

The Abt switch is a kind of railway switch used on funiculars (inclined cable railways) that doesn’t have any moving parts. It allows two cars to pass each other going uphill/downhill while sharing the same tracks. While most train switches rely on physically moving a section of track so the train goes one way or the other, the abt switch doesn’t move at all. Instead each carriage has a grooved wheel which makes it turn left or right at a junction by sticking to the track on one side.

    draw double and some of your dose and then push it out into the vial to your dose, should deal with any air bubbles (and any left will be too small to be significant) (not that they really are significant tho ppl have anecdotaly reported more pain)

        with the different viscosity of oil etc it looks like a llt more in the end

        i switched from im to subq and despite now experiencing what looks like a significant amount of leakage in reality my levels are the exact same :3

        if you have a large enough air bubble yes itll mess with dosage, but at that point its not an air bubble more just… space that wasnt filled

          Oh damn, I haven’t had anything but (sometimes) the tiniest pin prick of blood imaginable come back out.

          Fair, I’m not sure where the line between air bubble and empty space is tbh ohnoes
