Are endotoxin tests usually worth it?

A thread drawing fresh community attention to endotoxin testing practices has surfaced unresolved questions about whether standard safety thresholds — often cited at 350 EU per hour for a 70 kg adult — offer adequate assurance across the varied dosing frequencies common in peptide protocols.

We have been seeing a lot of high endotoxin results recently and seeing that for a 70kg male they can take up to 350 EU per hour. That seems like a lot when even the recent test only showed 2300 EU in the entire vial. Just wondering if I'm missing something about endotoxin build up or something.

depends on if it’s something you’re injecting once weekly or daily or multiple times daily.
