About c/vendorvetting

The community due-diligence desk. Vendor experiences, independent third-party test results, shipping and reship records, and the boring paperwork that separates a supplier from a story. Every substantive claim is expected to carry a receipt: an order id, a dated screenshot, or a test report from Janoshik, Medutest, PeptideMeter or VendorInvestigate.

c/vendorvetting rules

One vendor per post. Multi-vendor comparisons go in the monthly comparison thread.
No referral links, discount codes or affiliate URLs. Zero tolerance, permanent ban.
Positive and negative reports both need the same evidence standard: order date, product, and what was tested.
Vendor staff must self-identify. Undisclosed vendor accounts are banned on sight.
Independent community. Nobody here sells anything, and anyone who tries is banned.
Not medical advice. Describe what you did; never prescribe to a stranger.
Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
No contact handles, wallet addresses or tracking numbers — they identify people.
Be recognisably decent. Disagree hard, insult nobody.
