DIY Endotoxin Testing for Peptides: Worth the Cheap Setup or Nah?

A thread drawing community attention to the practicalities of at-home endotoxin screening for research peptides has surfaced a tension between consumer-grade testing as a personal safety measure and the higher evidentiary standard vendors are likely to require before issuing refunds or replacements.

If your goal is simply to put your mind at ease, go for it. If your goal is to get refund or replacement from a vendor, an official lab result will likely be necessary.

I would probably do this if I could get my hands on them here. Even if I wouldn't get a refund, I'd rather not get sick and throw away my haul than get sick and throw away my haul : p
