There’s a difference between your usual pip, and a hot burning sensation whilst pushing the plunger in.
And also it is not part of the game lol. Especially with your normally dosed oils, pip can be avoided (high concentration yes I’ll agree it’s normal).

Something is different. When you use the same brand for years, and all of a sudden you start getting bad pip, something has changed.

Even lowering the dose for daily shots, mixing with other oils, it’s still burning or extreme pip.
