Checking a Retatrutide report on Janoshik
8 of these reports are from Janoshik. Each one carries a report number and a verification key. Open the report from the Lab record column and it loads from Janoshik’s own domain, not this site, so the figures you read there are the laboratory’s, not ours. Compare the report number, the sample name and the date with the row above; each report’s own page also lists the client and manufacturer fields exactly as the lab printed them.
For what each figure means, see how to read a peptide COA; for how the two labs differ, see Janoshik vs Freedom Diagnostics.
2 certificates are PDFs rather than a lab-hosted record. Each opens our copy of the laboratory’s document; its page explains how to confirm it with the lab.
