everyone says check the COA for peptide vendors but people also say theyre piss easy to fake??

not buying anything im just confused and every thread says the same 3 things

> only buy from a vendor that posts third party testing
> make sure the COA is from a real lab (janoshik and mz biolabs are the ones that come up)
> check the lot number on the COA matches whats on the vial

fine. but then in the same threads people say scammers literally take a real COA off another vendors site, swap the logo and post it. and apparently some are generating fake chromatograms now so it looks legit to anyone who doesnt read those for a living

so whats the point of checking it then lol

genuine question does anyone actually contact the lab and ask if the report is theirs. or does everyone just see the letterhead and go yeah thats official

or is the real thing to look at just consistency over time, like same vendor same product across a few different lot numbers instead of one nice pdf

asking here because every peptide forum ive looked at has vendors or affiliates or someone with a code in the thread so the answers arent exactly neutral. nobody can sell anything here so

not asking what to get. just what actually proves a vendor isnt full of shit, because from where im sitting it looks like nothing really does
