We send vials to Janoshik Analytical, an independent laboratory in the Czech Republic with no stake in what we sell. Their reports live on their server, not ours — we cannot edit them. Every figure below links straight to the lab’s own record.
Every report we have — including any we would rather not publish.

Don’t take our word for it — that’s the point. Open any report above and it opens on janoshik.com, not here. Each carries a unique key you can enter at janoshik.com/verify to pull the same record independently. If a figure we publish ever disagrees with the lab’s record, believe the lab.
These were blind tests: the laboratory was not told which peptide each sample was. It identified the compound and measured it independently. That matters, because a test you cannot steer is worth more than one you can — and almost nobody in this market publishes one.
A purity percentage tells you how clean the material is, not how much of it is in the vial. Both numbers are here. Every vial we have tested came back over its label — but the same field would show it if one ever came back under, which is exactly why it is worth reading.
Independent reports cover the batches listed above — not our whole catalogue. Products without a published report carry our supplier specification of >99% HPLC, which is a specification, not a measurement, and we label it that way. We would rather show you three numbers we can prove than ninety we cannot. More batches are in testing.
Janoshik Analytical, an independent laboratory in the Czech Republic. They have no commercial relationship with our supply chain and no stake in the result.
Yes — that's the point. Every report is hosted on the laboratory's own site, and each carries a unique key you can check at janoshik.com/verify without involving us.
The laboratory was not told which peptide the sample was supposed to be. It identified and quantified the compound independently, so the result cannot have been steered.
Not yet. The batches listed on this page have published independent reports. Everything else carries our supplier specification of at least 99% HPLC purity, which we state as a specification rather than a measurement. More batches are in testing.
