The real reason it looks like a pill bottle is since the artists for these stories use premade 3d models as bases for their drawings (those can often be seen in the backrounds as is without any tracing on top as well) (just a way to speed up drawing these stories)
Most likely there is no premade model for a vial, but there is a model for a pill bottle, so theyre stuck using that.

WAIT SOMEBODY POINTED OUT HOW KEITH INJECTED HIMSELF WITH THE MEDICINE THIS is making me crazy HAHAHAHAH I'M HAVING A FIELD DAY WITH THIS TODAY.
I KNOW THIS IS FICTION but I just have to nerd out. So I'm saving y'all cause I'll be nerding out in a bit.

- Yes, you can't reuse injections, they are a one time thing— more importantly inject somebody with it after using it on yourself.
- Risk of developing immunity
- This is way too unsanitary (I mean, well)
- Did he even use atleast some rubbing alcohol? (Risk of contamination)
- There are more but I can't put them to words (English ain't my first language(
