Endotoxin Warning

A safety thread drawing community attention for the second consecutive day has surfaced confirmed endotoxin readings in a 30-milligram peptide vial that researchers calculate exceed the standard 5 EU per kilogram per hour threshold by a factor of several times, prompting self-reported gaps in routine testing practice among participants.

Thanks for starting a discussion on this. I don't personally test for anything and this has been a wake up call. Out of general concerns this test has raised, I asked chaptgtp about how bad it is. I'll put the response below, but would appreciate anyone more knowledgeable correcting the record or expanding on relevant details

The 1360EU is an estimate. The actual result could be wildly different. The confirmed result is 2306EU. In a 30mg vial. 5EU/kg/hr puts the maximum EU for threshold at 350EU per dose in a 70kg person, 500EU in a 100kg person. As the maximum dose of tirz is 15mg, that is what should be used to determine is a vial is a fail. 2306eu/vial = 1153eu/15mg …
