I got some really discounted rosin and I was looking to convert a gram or two of it into cartridges. I’ve been reading that most people use a glass syringe to fill them but I was reading another thread that you just go to your local pharmacy and get a normal plastic syringe. Anybody have any advice or experience?

You need to decarb the rosin, which is why it says heat for 24-48 hours. It didn’t take that long when I did.

I use a mug warmer, and after its decarbed you can inject it immediately or let it cool and warm it back up a hair to make it less viscose.

They say glass, because you CAN melt the plastic if the oil is too hot.
