Needing advice on pen usage

[Llennon]

Hi my dad has just done his first mounjaro injection and he said it doesn't look like the pen as gone down any has this happened to anyone before? I will add the picture of hospital pen below.

It's not the best photo, but that looks like one dose used.

This may help.

Can’t really tell from the photo. Hope this helps

*edited to say… Sorry didn’t see pp photo

Thank you the pen looks like it's in-between the full pen and first dose pen on the pictures.
