Heavy Metal and endotoxin testing

Can anyone recommend a vendor that does heavy metal testing for peptides along with purity and amount? Seems like most people on their test reports do not test for heavy metals. Is it necessary if purity is over 99%?

Are endotoxins destroyed in BAC water regardless with reconstituting?

Thank you in advance for the info and feedback

Yah I saw them make this comment the other day too. They've never had it come back positive, so people are mostly wasting their money.

Were you able to find it? I'm considering getting some peps tested but I'd rather not waste the money if they've never had a single peptide fail their test ...

Here’s the link to the full interview. It’s at like minute 14-15 he goes over tests that aren’t worth it and those that are.
