A pen is...

I finally filled a cart put it into my new pen and injected, hurray! Yet I realized it's big, and less steady than a small syringe braced by my hand. I am thinking those flat top pen needles are a good idea.
What kind of pens did you use? What is the difference between Open End and Closed End. Is there any advantages to one over the other?

The open end has a moving cover thing that lets you stick yourself without seeing the needle. That's pretty much it. I bought them thinking I didn't want to see the needle .. but then I didn't trust that it was in me correctly and just take the cap off anyway.

I'm right behind you! My pens (one for tirz, one for klow) came last night, and my filters are coming today. I won't need my tirz one for a few more weeks, because I'm working on a vial of compounded and don't want to burn a cart for three doses, but I'm ready to go with my KLOW vial!
 
Thank goodness. Now you can free your budget to buy the peptide-of-the-day, the group-buy-of-the-day, a dozen NovoPen 6 pens, and customized, 3D-printed storage solutions, haha.
…and don’t forget the usb-powered refrigerated pen holder and a portable solar backup battery so you can carry them through the wilderness; I hear that’s how Sacagawea kept her figure.
