Filling pen - different technique?

[Dubbs]

I saw a video of someone purging the air out of the new empty pen vial first by driving the stopper to the end, then filled the vial with the peptide. No need for vent. Any thoughts?

Per Jeff's video, this will render the vial no longer sterile and should therefore be avoided. Venting is a pretty easy step so really not worth skipping.

@Canineriot ah. I didn't remember him saying that in his video. It's been a while since watching. I figured there had to be a reason to not do it this way... Thanks

No problem!
