Is Buffered NAD+ ever yellow?

[Nopenada]

I have not reconstituted yet, but the yellow pucks are off-putting, to say the least.

My research to this point is that anything that reconstitutes to a color other than clear had better have copper or 5-Amino in it, otherwise it’s trash. Is there any hope that a yellow puck will reconstitute clear, or am I in for some urine-adjacent disappointment?

Your NAD+ should definitely not be in a clear vial, but a mild yellow tint is normal for NAD+, as a small fraction of NADH is often in it, and that has a natural yellow tint.

Was just going to post about this. I'm on my 3rd vial of nad plus. All have been sold as bufferd. First 2 were clear. 3rd is from new supplier it's yellow tint. I googled and yes nad can have yellow tint.
But now I'm wondering if my first 2 vials were legit? I'm currently taking a extra few days off nad before I start the new vial. Since it looks so different.

What color do most of you see in your nad plus?

I can't tell what color the puck is. It comes in a dark amber glass vial. In the syringe it looks clear. I know it is legit from the side effects.
