Disclosure first: I work with Peptheon, so read this as a supplier's answer rather than a neutral
one.

On the question itself — the lab's name matters less than whether the report resolves from the
lab's own domain for the batch printed on your box. Three checks catch most of what passes for
documentation: the batch number on the packaging matches the number on the report; the report is
served from the lab's own domain rather than a screenshot somebody posted; and the values come with
units and a method, not a bare percentage.

Being straight about our own line: we publish batch documentation only where the manufacturer
publishes a lab report. Nordic Peptides, who make the retatrutide we sell, publish none, so that
product page carries no certificate rather than one we cannot back — send us your order number and
the batch printed on your box and we will request that batch's paperwork and tell you either way
what came back. The retatrutide is sold as sealed manufacturer pens, we ship within the EU only,
tracked delivery with one flat €20.00 fulfillment and delivery fee per order regardless of order
