Independent lab verification

What's actually in the vial.

We anonymously purchase research peptides, ship them to accredited labs under blind codes, and publish graded reports comparing what was measured to what was claimed.

We don't sell any compound — ever.

No vendor partnerships. No advertising revenue.

Reports funded entirely by members.

The process

How we test

Anonymous purchase

We order products as regular customers through normal retail channels. No vendor is informed they are being tested. Products are logged at intake under our blind code system before anything else happens.

Independent lab analysis

Vials ship to ISO-certified third-party facilities under blind codes. HPLC and mass spectrometry measure dose, purity, and identity. The lab does not know the vendor name at any point in the process.

Published findings

Lab results are published in full with a graded verdict comparing measured values to vendor claims. We report what we find — passing and failing results alike. No edits, no omissions, no softening.

Chain of custody

Every product receives a unique blind code — such as VR-0428-K — at intake. The vendor name is never transmitted to the lab. Results are matched back only after analysis is complete and sealed.

What a report looks like

A score that means something

Every report gives you a letter grade backed by measured lab values — not marketing copy, not crowdsourced reviews. The lab found this. Here is what it means.

The grade is a summary

The letter grade (A–F) reflects dose accuracy, purity, and identity confirmation together. A failing dose offsets an otherwise clean purity result — the grade doesn't hide weak sub-scores.

Exact measurements, not estimates

We publish the measured value — 9.84 mg — not "approximately 10 mg." Precision is the point. We don't round away variance that might matter to you.

One batch, stated plainly

Each report is scoped to a single batch. A single result is not a guarantee of every vial a vendor has ever shipped — and we say so explicitly. Credibility comes from transparency about limits.

Member-funded

VialReport is an independent publication. We don't sell any compound, take advertising from vendors, or earn affiliate commissions. Our only revenue is member subscriptions — which means the only thing we're incentivized to do is publish accurate results.

When a product fails, we publish the result. When a vendor's claim doesn't match what the lab measured, we report the discrepancy exactly as measured. The data is the product. There is nothing else to sell.

Named founder. Accountable reporting.

This publication is founded and run by Shawn. There is no anonymous editorial board. We put a name behind the reports we publish — because that is what accountability looks like.
