How Peak Peptides tests

Every batch goes to a laboratory that does not work for us, and the certificate is published in full rather than summarised.

How a batch gets released

Why publishing matters more than testing

Almost everyone in this category says they test. Very few will show you the document. The useful question is never "do you test?" — it is "can I read the certificate for the batch I was actually sent?"

That is the standard we hold ourselves to and the one worth holding anyone else to.
