Verification of purity, not promises
Purity claims are only worth anything if you can check them. Here is exactly what we test and how you can audit it.
Published lab reports
Not a promise that testing happens — the certificates themselves, published as the laboratory printed them. The letterhead, the report number and the key are theirs, so what you are reading is their document rather than our summary of it.

Open the full certificateVerify at the labEach report covers the batch submitted for it and no other. It is evidence about that material rather than a guarantee about every vial ever shipped, which is why these are dated, numbered and published one at a time instead of summarised into a badge.
Every mark here opens the document behind it
Anybody can draw a badge. These are the ones we can hand you the paperwork for: a named laboratory, a dated report, and a figure you can check against it. Where a mark is our own operating standard instead of somebody else's document, it says so on the badge.

Independent laboratory
Janoshik Analytical
The assay is run by an analytical laboratory we do not own and do not pay for a result. The report carries their letterhead, their number and their signature — not ours.
- Third-party document
Lowest published purity
98.469%
Not our best result: the worst one we have ever published. A number built on the best batch is a number the next batch breaks, and this one is meant to survive.

Complete reports, printed as the laboratory printed them. Not a summary, not a cropped screenshot of a results table with the letterhead cut off.
- Third-party document
Content weighed, not claimed
3
Reports stating how much peptide the vial actually held, against the milligrams on its label. Purity tells you what it is; this tells you how much of it there is.

Verifiable with the lab's key
4
Each report carries the code the laboratory issues for checking it on their own system. That check runs through them, which means it does not run through us.
- Our own standard
Cold chain on dispatch
Insulated packaging with phase-change coolant on every route we run. This one is our own commitment — no outside party audits it, and the badge says so.
Take the certificates with you
Each report as a PDF, the whole page exactly as the laboratory issued it. For a purchasing file, a colleague, or a batch record.

Peptide shipping to Argentina and the region
Cold-chain packaging and tracked delivery, from whichever operation is closest to the destination.
Argentina
Local dispatch from the Argentine operation for destinations in the country, with documentation in Spanish.
International destinations
Transit is quoted per destination, because import rules for research-use materials differ by country. Every cross-border shipment carries research-use declarations and a safety data sheet.
Packaging
Discreet insulated boxes with phase-change coolant. Contents documented as laboratory reference materials.
Customs documentation
Research-use declarations and safety data sheets are prepared for every cross-border shipment, and reviewed with you during the consultation.
