Mystery peptide with high endotoxin results

An unidentified peptide sample registering more than 1,000 EU per vial — a level researchers in the discussion describe as likely understated — has drawn community attention to endotoxin contamination risks, even as the vendor behind the batch remains undisclosed pending further review.

Looks like we may have a new endotoxin level winner, at over 1000 EU/vial. Estimate provided is probably low This is all that was posted, testing group is choosing to keep vendor hidden, for now.

I would. Vendors don't typically refund or reship based on endontoxins, AFAIK. I've seen a few NAD+ samples test >100 EU/vial lately, but nothing over 1000. I saw Peter M discussing this today, but it was a private test and the vendor and peptide wasn't mentioned.
