Another point to add is its always slower the bigger the syringe is. Pressure = force / area. I shot 4ml in a 5ml syringe today and it took about 3-4 minutes.

and do you use syringes with a rubber at the plunger? these inject way slower too...
It's never a walk in the park with a 5ml syringe. I've applied so much pressure before that the syringe has dislodged from the needle and the oil has sprayed everywhere, leaving the needle in my leg/shoulder, and this has happened on fair few occasions!
happened to me too, but evne with 2 and 3ml syringes... mostly when i tried pinning hard to reach spots with 27Gs
never any issues with 25gs and 5ml injcects
The gauge you're using is probably too small for the substance you're trying to inject. Try 21 gauge syringes. They are large enough that you don't need a lesser gauge needle to fill the syringe.
injecting with 21gauge needles? oh brother
OP; i put my vials on the stove for a couple seconds. swirl until the oil gets hot evenly, vent, inject
goes in like butter through 25gs
