Certificates of analysis

A certificate of analysis is the only part of a peptide transaction that can be checked by someone who was not present when the material was made. Most of what is wrong in this market is wrong at the certificate.

What a usable certificate contains

A lot number: Matching the number on the vial you received. A certificate that names no lot describes no particular material.
The laboratory, named: With its accreditation. "Third-party tested" without a laboratory name is not a verifiable statement.
A purity figure and its method: Chromatographic purity for that lot, with the method stated, rather than a rounded figure quoted brand-wide.
An identity result: Measured mass against expected mass. Purity and identity answer different questions.
A date: Analysis is a snapshot. An undated certificate cannot be matched to a shipment.

The specimen-certificate problem

A specimen certificate is a representative document shown for a product line rather than for the material shipped. It may be entirely accurate about some lot, at some time. It tells you nothing about the vial in your hand. The distinction to insist on is lot-specific, and it is the distinction our Lot Standard is built around.
