How are peptides made?

Nearly all research peptides are made by chemistry. The chain is put together one amino acid at a time on a solid bead. It is a well-known factory process, not something taken from an animal or plant. That is why the same product can come from many different makers with very different quality control. And that is exactly why an independent test report (certificate of analysis) matters more than the seller's own description.
