What is VendorInvestigate?
VendorInvestigate is an independent peptide-vendor testing bureau. We acquire peptide products on the open market and through community intake, submit them to contract laboratories under blind codes, and publish every laboratory result — favourable or not — as a public case file. No vendor pays for a verdict and no verdict is for sale.
How many vendors and products does the bureau cover?
The public record currently holds 24,294 individual test results across 16,294 physical samples, covering 198 vendors (subjects) and 295 distinct compounds, analysed across 7 contract laboratories.
How does the bureau score a sample?
Every sample is graded on a 0–10 scale where higher is better. Scores map to letter grades: 6.0+ is A (Cleared), 5.0–5.9 is B (Cleared), 4.0–4.9 is C (Under Review), 2.0–3.9 is D (Under Review) and below 2.0 is E (Failed QC). Subjects with too little evidence are filed as X (Sealed).
Which laboratory tests are run on each sample?
Each vial is run through a six-assay panel: identity (LC-MS), purity (HPLC-UV), potency/content versus label (HPLC), heavy metals (ICP-MS), bacterial endotoxins (LAL) and sterility/bioburden (culture). Each assay is reported on its own — a sample that passes purity can still fail on toxic metals, pyrogens or sterility.
Is the bureau independent? Does it sell peptides?
Yes, it is independent and it does not sell any compounds. The bureau buys samples the way a customer would, plus accepts community intake. Laboratory identities are withheld and blind-coded to prevent vendor interference. No vendor can pay to change, remove or improve a verdict.
How can I verify a batch number?
Vendors enrolled in the batch-verification programme print a registry number on each lot. Enter it on the Verify a Batch page to confirm the physical lot was analysed by a bureau contract laboratory and to view its verdict.
How do I submit a sample for testing?
Use the Submit Evidence page for field-intake instructions. Accepted compounds are tested free as part of the community programme; sample intake is limited to shipments originating within the United States. Your vial becomes part of the public record.
Is anything on the site medical or purchasing advice?
No. VendorInvestigate publishes laboratory findings for educational and harm-reduction purposes only. Nothing on the site is medical, legal or purchasing advice, and verdicts describe the tested samples only — they do not guarantee future batches.
