What to check on every report

Four things, in this order. Testing 101 goes deeper.

Testing 101 →
  1. IdentityThe compound named on the certificate is the one on the label.
  2. PurityHPLC purity — research-grade peptides usually report 98–99%+.
  3. ContentMeasured mg per vial against the strength printed on the label.
  4. VerifyA recent date and a verification key you can check with the lab.
Usually coveredHPLC purity & contentConfirms the right peptide is in the vial, how pure it is and how many mg it holds.How to read an HPLC result → Rarely coveredEndotoxins (LAL)Brand reports seldom include endotoxin testing. The community runs it on real orders.Why endotoxins matter → PeriodicTFA salt (NMR F-19)Checks whether a cheaper TFA salt form was used. Worth a spot check every few batches.Reading NMR F-19 →

Reports are supplied by the brands for a specific batch — a strong starting point, not a guarantee for the vial you receive. Testing 101 explains why buyers still run their own third-party tests.
