Every peptide sold for laboratory research should come with proof of what it is and how pure it is. At Healio, that proof is an HPLC certificate of analysis tied to the specific batch you receive.
Why HPLC?
High-performance liquid chromatography separates the compounds in a sample so purity can be measured precisely. A single stated percentage on a marketing page is not the same as a batch-specific certificate you can read yourself.
What to look for
Identity confirmation, a purity percentage, and a batch or lot number that matches your vial. If any of those are missing, ask before you buy.
For laboratory research use only. Not for human or veterinary use.
