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