So I was just watching youtube videos to see if I can discover a tidbit of new information and I came across this video that claimed injection pens bought from Aliexpress are "no good." Now I had just recently bought 2 of them from that website but hadn't used them yet.
Oh no, I need to test them I guess. Since I had just got done mixing a batch of KLOW I had all the supplies I needed to test all my pens ready to go. So I took the old cartridge I was going to throw away and filled it with 3mL of plain water and loaded into one of the new pens. Following the method in the video I tried to dose into the syringe 20 units. Oh no .. it was only 14 units! Hmmm. I had to try again to try and see what caused the problem. So I emptied the syringe and turned the dial once more to 20 and slowly pushed the button to see if it skipped or something It didn't .. it filled the syringe to 20 perfectly. I did it again .. slowly .. again it was correctly 20. Then it clicked in my head .. it wasn't the fault of the pen .. it was user error. If you press the pen too fast you will not get your full dose. So I tried once more and this time I slammed the button and proved that pushing too fast will result in an under-dose.
Just to be on the safe side I went through and tested all my pens, even the ones that had cartridges of stuff in them. I just carefully removed the vials and set them aside, tested the pen and then put the good stuff back in and wiped everything down with an alcohol wipe. All my pens gave the correct dose as long as I did it slowly.
