Third-Party Peptide Testing Guide
Third-party testing on this site means the Janoshik report linked to that product. It covers the sample on that report. 21+. Research only.
One report, one sample
Janoshik task numbers on the product pages are the third-party records for those listings. GLP-RT3 is task 149759. GHK-Cu is task 165759. A passing description of one does not cover the other.
The report's date, sample name, and results are the scope. A later vial needs its own document if you require one.
Third-party does not mean every test
These certificates do not all include endotoxin, sterility, residual solvents, or a biological assay. Read the test name. NIST's reference-material program is a different system. Do not describe a Janoshik task as a NIST standard.
The shop publishes the report it has. It does not claim a test that is not on the page.
This page is laboratory education for adults 21 and older. It is not a dosing guide, a treatment plan, or a schedule. Not for human or veterinary use.
