I've been looking at a UGL and a lot of items aren't listed as being #mg/ml and what size of vial it is.. it seems like I have seen 20ml vials and some smaller.

If an item is just listed as for example "test-E 500MG" is it safe to make an assumption as to what size the vial is?

i've yet to start a cycle and i'm still learning. sorry if this is a stupid question.
