How we test

Every vendor review on Peptifact runs the same protocol. Fourteen points, in the order they happen, from the day we place an order to the day a score is published. No exceptions and no sponsored fast lanes — a vendor cannot pay to be tested sooner, tested differently, or tested at all.

Buying the product

1. 01Two anonymous orders per vendor, three to four weeks apart, from different addresses. We never identify ourselves and we never accept a press sample. The gap is deliberate: it buys a second batch, a second lot number, and a look at how a returning customer is treated.
2. 02The same product from every vendor. One compound, one strength, one format across the whole cohort. Reviews that test different products are not comparable, whatever the scores say.
3. 03The listing is recorded on the day we buy. Price, stated purity, size, and the certificate the vendor links to, captured as they read that day — because listings change, and a claim we cannot show is a claim we cannot report.
4. 04The vendor's own certificate is downloaded before the vial arrives. That document is the thing being checked. It is never the check.

What arrives

5. 05Delivery measured against what was promised — the date offered at checkout against the date it actually landed.
6. 06Cold chain judged only if it was advertised. A melted ice pack matters when a vendor sold cold shipping. If they never claimed it, we do not mark them down for it.
7. 07The vial is documented before anything else happens — label, cap and seal photographed; compound, stated milligrams, lot number, expiry, manufacturer and storage instructions transcribed exactly as printed.
8. 08The lot number is checked against the certificate. Three answers are possible and we publish whichever is true: it matches, it does not match, or the certificate carries no lot number at all. The third is more common than buyers expect.
9. 09Everything else in the box is listed and photographed, including any leaflet, chart or mixing guide, front and back. What a seller puts in the box is part of what a seller is selling.

Independent laboratory work

10. 10Identity and purity are verified by an independent laboratory against certified reference standards — not by us, and not by the vendor. Where the lab's result and the vendor's certificate disagree, we report the disagreement exactly as found.
11. 11The vial is assayed for how much peptide it actually contains. Purity and content are different questions: purity describes the material that is there, content describes how much of it you were sold. Most published certificates answer only the first.
12. 12One vial goes to the lab, one stays sealed. If a vendor disputes a result, there is a second untouched sample to re-test — which is the only reason a dispute can ever be settled rather than argued.
13. 13The laboratory certificate is filed with its verification code intact, so a reader can confirm our result came from the lab we say it did.

Service, and the number at the end

14. 14Every vendor is asked the same question and priced the same way. We request the certificate for the exact lot we received, and log how long the reply took and what it said; we screenshot the refund policy as it read that day; and we calculate price per verified milligram — what the product cost against what the vial was proven to contain, not against what the label claimed.

What we publish, and what we will not

Every review lists what a vendor failed, not only what it passed. Findings carry their order dates and the documentation behind them. Scores change when the evidence changes, and the page says when and why.

Where a step could not be completed, we publish what was established and state plainly what is missing. A review is void — and does not run — if the vendor knew who was ordering, if only one order was placed, if there is no independent laboratory result, if no lot number was captured, or if a score was written before the assay came back.

No vendor has completed this protocol yet. The first cohort is being ordered now. Until a vendor has been through all fourteen points, you will find no ranking and no score for it here — that is the point of publishing the protocol before the reviews rather than after.
