Interpreting Endotoxin Results on a NAD+ Vial

15 replies5 peopleMar 6, 2026☆ Follow
Summary

How should someone interpret an endotoxin test result on a 1000 mg NAD+ vial for planned low-dose subcutaneous use?

The thread examines a test showing over 10 EU per vial and roughly 29 EU total. Participants discuss whether dividing the vial into 22 doses lowers exposure enough to be acceptable and whether the numbers match common peptide results. Several users note that published limits are usually expressed per kg body weight per hour, making direct comparison difficult. The group agrees retesting is sensible and that IV administration carries extra risks.

What this discussion establishesWhere people disagree

Whether the reported level is high enough to discard the vial or simply requires dilution and retesting.

Still open

Exact conversion of the vial total into a safe per-dose figure for a given body weight.

Nothing here is advice.

Hi there! Could you please help me understand this endotoxin test? I ran it on a 1000 mg vial of NAD+. I plan to begin at 25 mg and later move up to 50 mg every three days. The endotoxin level seems high to me. Should I send another vial to a testing lab? I have not seen this much endotoxin on other peptide reports. Thanks for any input.

From what I gather a person might tolerate two units according to their weight in kilos each hour. With a container that holds twenty nine units in total there ought to be no difficulty. I'm unsure whether I'm interpreting the test numbers right though. It appears they indicate more than ten units inside each container for an overall amount of twenty nine units.

Oh, do you have the full report?

I wish someone would explain this eventually and share the details here. Spent ages looking into it but can't make sense of it at all since the limits get calculated based on how much endotoxin gets taken up relative to someone's weight over time. It would be great to have a dedicated discussion about figuring out endotoxin levels when doing subcutaneous or muscle shots involving those compounds. Most of what's out there talks about injections near the spine instead. This is really annoying.

I'm thinking about splitting this into twenty two portions. That reduces the expense for each serving quite a bit. It seems much improved. Still, I will definitely check again, since two additional containers must be sent out too, allowing them all to travel together in one package.

Weight is also counted in and my rat is still 25 kg overweight.

That reasoning checks out. It accounts for every seller clearing those bacterial toxin checks without issue. I've compiled my own list of all the results and reviewed them to confirm.

I've seen a few users here trying intravenous administration with it. That strikes me as potentially risky. Sterility worries come up immediately, and getting endotoxins straight into the bloodstream seems harsher than a subcutaneous route. In my view only standard pharmaceutical cleanliness protocols count as acceptable for vein delivery, and anything short of that doesn't.

I agree it's unwise for anybody to attempt intravenous medication use outside a proper clinical setting.

I have another question: the lab is using the dot in the numbers of the endotoxin amount. Does this mean 2 and a bit? Or is it 2410 EU? Just confusing for me.
