WHAT ARRIVES
What is in every vial, and what proves it.
Lyophilized powder
Freeze-dried and sealed. The format peptides are held in for stability.
A lot number on the label
Every vial is marked. That number is the key to its certificate.
A certificate for that lot
Not a catalogue average — the assay for the batch in your hand.
Identity by mass spectrometry
Confirmed, not assumed. Molecular weight is on the certificate.
Purity by HPLC-UV
The figure is published per lot, whatever it comes in at.
Scientific naming
INN names and CAS registry numbers, on the label and the page.
