Frequently Asked Questions
Quick answers to common questions.
They are short amino-acid chains supplied only for legitimate in-vitro, analytical and laboratory research, such as work with cells, tissues and biological samples. They must never be administered to humans or animals, and are not for personal experimentation, clinical or veterinary use, or compounding.
A certificate of analysis is the third-party laboratory report for a specific production lot. Each shipment carries a lot identifier printed on the vial; enter it in the COA archive to pull the matching report.
Each certificate reports three results separately: identity by LC-MS (mass spectrometry), chromatographic purity by HPLC-UV, and net content - the peptide mass measured in the vials sampled. HPLC purity alone does not establish identity, exact quantity, the absence of all contaminants, sterility or suitability for a particular use.
