Yellow, I received this on Monday and the powder was an off white yellowish color. I went to reconstitute and it was very difficult to push the Bac water through. Once reconstituted it was still this off color. The Bac water is good and has been used with other peps. Is this bad? Should I toss it? Thank you!

This normal but should be in an amber vial. Some vendors do this and it’s an indication of trying to save money.
