possible bad BAC water affecting results and bad side effects?

So I got my 10mg vial of Reta from the same source a girl I am close with and she’s had wonderful results so I used her source for it. What I didn’t do that she did, was purchase the same BAC water from the source. They use Hospira for theirs. I ordered my BAC water off Amazon (idk the company since they took it down)

I’ve been on Reta since Jan of this year. I did the whole start at 0.5mg for a couple weeks then go up like I saw people say to do to minimize sides.

The first couple weeks I was great and lost a good bit of weight and my food noise only came back towards end of week. Well eventually, even with going up in dose, I stalled. I’ve even gained? And the sides are god awful the first couple days after pinning which I would say is bearable IF I was seeing results. But I’m not.

So my question is: can bad BAC water affect the efficiency of Reta and also cause horrible side effects? I did reorder from the same course and got the Hospira with it so I will try it on Saturday/Sunday when it’s time to pin again.
