The task number is the ID
Blue Collar files each third-party report under the Janoshik task number printed on it. Tesamorelin is task 134410. The GLOW blend is task 136730. If a picture arrives with that number cropped off, you cannot tell which batch it belongs to. Start there.
A logo is easy to copy. A task number you can open on the COA page is the check.
The sample name has to fit the vial
Read the sample line next to the label before you trust a result. Task 136730 is a blend report. It lists GHK-Cu, BPC-157, and TB-500 as separate lines. That file does not turn into a GHK-Cu 50 mg certificate because someone renamed the JPEG.
Spelling trips people. The Epitalon listing is spelled Epithalon on task 135095. Same catalog item, different spelling on the paperwork. Write what the page says.
Open the file, do not trust a crop
Dates, the lab name, and the sign-off sit where a crop likes to cut. A square that keeps a big percent and drops the date is not the record. The COA page on this site shows the report image tied to that task. Compare the file you were sent with that page.
If the task number matches and the image does not, treat the forwarded file as unverified.
A real percent can still be the wrong sheet
Authenticity is the link between the file and the vial, not the size of the purity number. A genuine report for a different batch is still the wrong report. Match the task, the sample name, and the date before you copy any result into a notebook.
We do not retype the lab's figures into a cleaner table, and we do not redraw the chromatogram.
When the match fails
Stop filing it. Ask for the task number and the uncropped file. Do not borrow a result from a related name because the vials look similar.
