A real COA can still tell the wrong story.
A certificate of analysis records results for one submitted sample. What it's worth depends on whether that sample matches the product being sold, whether the report is authentic, and whether the tests back up the claims.
WHY WE STARTED
The gap between a test result and the product sold.
A real laboratory report can still create false confidence if nobody can tell where the sample came from or how it relates to what buyers receive.
A QR code cannot close that gap on its own. Neither can a purity percentage. Source Standard exists to make those connections visible, and to make the limits of the evidence clear.
Four questions behind every report.
Is the report real, and does it belong to this product?
A legitimate report can be copied from another product, reused across later batches, edited, or cropped to show only a passing number. A QR code is only a link; it does not prove what is in the vial.
How Source Standard handles this: Every report we publish comes from the laboratory for a product we purchased ourselves.
Who chose the sample?
A laboratory can accurately test what it receives while buyers receive something different. When the seller picks the sample, a known-good vial can stand in for inventory it does not represent.
How Source Standard handles this: We pick the product at random and buy it like a regular customer, with no advance notice to the vendor.
What do the numbers actually show?
High chromatographic purity does not, by itself, establish how much peptide is in a vial. A report cannot show the absence of anything it did not test for, and analytical results do not establish safety for human use.
How Source Standard handles this: We publish what was measured and explain the methods and limits on our laboratory page.
What happens if something looks wrong?
Quiet retests, quiet replacements, unclear manufacturers, and undisclosed paid rankings all weaken accountability.
How Source Standard handles this: If a finding raises a concern, we share the report with the participating vendor, follow up with another independent test, and update membership status when appropriate.
WHAT OTHERS HAVE FOUND
Labels and products don’t always match.
Products bought online have been found to differ from their labels in both amount and purity, sometimes by a wide margin.
Some products have been found not to contain the stated ingredient at all, while still being sold with paperwork that suggested otherwise.
Other concerns include borrowed or reused lab reports, hand-picked samples sent for testing, and products labeled with a manufacturer that did not make them.
These concerns do not describe every seller. They are why the sample, and who chose it, matters.
