VendorInvestigate presents itself as an independent watchdog bureau investigating peptide vendors. It is not independent of what it investigates, and its published record does not hold together.
Our technical audit establishes that VendorInvestigate is run by the same operator as the sites that appear to corroborate it: a vendor grading database, a second "testing" brand, and review forums, as well as the vendor shops all of them recommend. The network also quotes VendorInvestigate back to itself: reviews on the operator's forums reassure readers that a vendor's VendorInvestigate listing "checks out."
The site's account of how it obtains samples contradicts its methodology page. Its headline figures disagree under one stated cut-off date, and the same vendor appears in three grades at once. Large volumes of claimed results carry no laboratory identity, certificates, or underlying data. Alongside these verdicts, it sells paid vendor programs.
For you as a buyer, a VendorInvestigate entry carries no independent weight, whether it clears or condemns a vendor. A seller pointing to a listing there is pointing to its own network. Treat its verdicts, grades, and certificates as unusable.
