what are the best peptides to use with auto pens?

Pushing 40 units I use a manual pen to go slower.
What am I missing

As far as I know all peptides can be used with autopens. It’s the gauge of the pen needle that matters. It should be below 31 to avoid back pressure

Yep; you can use an autopen with pretty much anything, but if you are sensitive to Glow/Ghk or other peps, you might want to use a manual for slower injection. Like Stevepep says, you have to watch gauge as very thin needles (like the 32g i prefer) are likely to cause the cartridge plug to stick.

The needles were my issue for sure. I was trying to use a 33g and was getting very frustrated. I’m now using 31g and have no issues!

Just avoid oils in them.

Would an auto create a bubble not allowing the pep to spread out at 40-50units? I am using 31g on the convi and the gani one similar to convi.
