Brello

I received my 3 month supply from brello. 6 vials. All only a quarter full. I have no idea how much to inject. Doesn't say on the vial or my brello account. I'm on 7.5 mg. I've reached out to brello multiple times with no response. I was on 2.5 and 5 mg with you4you and injected 50 units each time. There's no way doing 50 units with these vials would last months. Any advice?
