TORONTO - eTradeWire -- The requirements are set out at https://peppycanada.com/standards.

A certificate records the findings reported by a laboratory. It is not a guarantee about a product.

Peppy's free education library explains how to read a COA and why purity, identity and quantity testing answer different questions: https://peppycanada.com/learn/reading-a-peptide....

"People shouldn't need to take a certificate at face value just because it has a laboratory name on it," Sandry said. "We want the paperwork to be something they can actually check."

Peppy's products are supplied for laboratory and research purposes only and are not intended for human use.
Tested products carry batch certificates from HYTE Research Division, and some also have a second certificate from Janoshik Analytical. Each tested product links its COA on the product page, with a laboratory verification link when the lab provides one. For batches still in the testing queue, customers can request the COA.

Peppy Canada, an online supplier of research peptides to laboratory and research customers across Canada, has published a written standard for the certificates of analysis (COAs) it accepts.

A laboratory certificate is only useful if the reader can understand what was tested and what the results mean.

Peppy's standard requires every accepted certificate to identify the issuing laboratory and state the testing method. It must also report the measured purity and measured content per vial.

Those last two measurements are not interchangeable. Purity describes one aspect of a sample's composition. Content tells the reader how much material the laboratory measured in a vial.

"A certificate should tell you what was tested, who tested it and what they actually measured," said Peter Sandry, founder of Peppy Canada. "If those details aren't there, the document isn't doing much work."
