Third-party tested my order out of curiosity and the mass came back consistent with the DAC version despite ordering no-DAC. Vendor says impossible. Institute testing found the same mislabeling pattern — anyone else verified theirs?
CJC-1295: got DAC when I ordered no-DAC — how common is this?

More common than any other mislabeling we see with this compound. The two forms have wildly different half-lives, so this is not a trivial mixup for research purposes. Mass spec is the only way to know.
Our specimen archive confirms: form mislabeling on CJC-1295 appears in multiple companies’ histories. It is why DAC verification is a standard finding row on those reports.
