Color change with my liquid pramipexole bottle

[mr_ectomorph]

I have 2 prami bottles in my fridge that I bought around 9 months ago. 1 of the bottles is half full. The other is full. The half full one has went from dark blue to veryy light blue. The full one is blue.

Why is that? I've been using it for the past 6weeks. I always shake my bottle before using it.

My bottles are from rui.

I'd get rid of the open one.

But mine was blue and became light blue and I didn't even touch it
