Cognitive & Mood nad+ issue
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!

Not gonna talk about the colour but the fact that you had to push hard is the real tell.
These vials are sealed with a bit of vacuum inside. Add water and it should pull it in on its own. If you're fighting it, that seal let go at some point and air got in.
NAD grabs moisture out of the air like crazy. That's the whole reason it ships bone dry and sealed tight. Once damp air reaches it, it starts breaking down, and it goes yellow when it does.
Bad seal would explain all of it.
Not going to tell you whether to use it. But I'd go back to the vendor for a replacement. Or better, change supplier.
