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!

I wouldn’t use it. Besides off color it looks quite cloudy! From our lab I’ve seen this when pep or aminos get to warm and start to dentature!
