It seems like this point has been totally lost around here so I felt compelled to put a fine point on it: vendor tests are a marketing tool and should not be trusted any more than claims made in a commercial. A vendor will not release a bad test to the public, you only see the good ones. “They’re testing great!” is meaningless if all those tests were funded and filtered by a party that has a serious interest in you believing they only produce high quality products.
Find some friends to get post-purchase testing done with, or find your way to a testing group. Testing groups see a large proportion of tests come back with underfills, unacceptable purity, contamination, or even the wrong peptide in the vial, and it happens with well respected and trusted suppliers. And yet you never see vendors providing you a test that says “our last batch has a degradation issue and a little semaglutide mixed in there for good measure.” They won’t ever tell you “yeah we stocked out of the last batch so are going to ship this one under that batch’s COA and number so we don’t have to eat a loss/risk people moving to another supplier while we wait for the testing to come back.” These things happen allllllll the time.
If you believe peptide sellers are your friends you are being naive — they are in the business of extracting money from you. Vendor testing is not to be trusted for things you’re injecting into your body because of this.
