A pen is...

[randompersonrandom]

Based on all the users comments I've seen; its the short needle. Try a longer one. I got 8mm for the KLOW, but some say longer.. we'll see..

I have the 8 mm's too, and can confirm that it's not a guarantee. I have tried an 8 mm needle, an 8 mm with a lot of rubbing after, an 8 mm with a lot of rubbing and then a shower, an 8 mm with a lot of vibration (I don't want to talk about how I got that done without buying a massage gun and I'll thank you not to ask), and a concentration of 14 mg/ml of the gck-cu. I have a few more things to try (an 8 mm into the thigh and then straight out to work out, a reduction of the dose by 25%, a reduction of the dose by 50%, a greater increase of the bac water and then the actual aneala protocol with the three pokes), and after that I'll just accept that doing KLOW means bruises in exchange for the non-bruised parts of my skin being prettier. Maybe. Man, if this was a boyfriend, I'd have broken up with him by now.

I havent tried their pen needles, but I bought the BD syringes and they actually hurt. The hype was wrong. I went back to the easy touch ones.

Actually not those, I use the Clearchoice comfort EZ ones.. for the peps that aren't in pens yet.

Yes BD needles actually suck now, they used to be really good years ago I avoid then dull needles from BD.

I bought sterilized cartridges but they don’t work well with automatic pens, which I prefer (too hard to push for the spring).
So now I use both types of cartridges, depending on the type of the next available pen.
Gansulin is my favorite all around, and Savvio for manual pens.
They both allow to detect what the remaining quantity in the cartridge is.

I may have missed it, but you mention you use both types of cartridges. Can you elaborate?
I’m noticing the same issues, where the plug is too hard to push for the spring.
If there’s a better cartridge, I’d like to take a look. Thanks!
