For research use only. Not for human or veterinary use.

Research deserves a higher standard.

Every product we sell is tested by an independent laboratory in the United States. You can read the full report before you order.

Why we started SÈVE

Research peptides should not require a leap of faith.

The first time we went looking for research peptides, almost nothing about it felt reassuring. Unfamiliar names. Enormous catalogs. The same promises on every site, none of which could be checked.

We wanted to buy with confidence. To know what was in the vial, who tested it, and what they found.

It did not exist. So we built it.

How we began

The SÈVE standard

The report is as easy to find as the product.

Research materials are made in batches, and one batch can differ from the next. A general certificate tells you very little.

So we test each batch on its own, before it ships, at an independent laboratory in the United States accredited to ISO/IEC 17025, the international standard for testing laboratories. We confirm the material is what the label says. We measure how pure it is. We check for bacterial contamination, heavy metals, and solvents left over from manufacturing.

Then we publish that report on the product page, beside the exact batch you are considering.

A short list.

The list is short because we only carry what we will vouch for.

Every product is tested the same way before it ships, with its current report beside it. If a batch does not meet the standard, it does not go out.

Verification

Every batch, on the record.

Every report is public: what was tested, how it was tested, and what the laboratory found. You will never have to request one.

Reports for earlier batches stay published too, so you can see how a material has held up over time.

Where can I find the lab report?

Next to the product. Every listing shows the report for the batch you are buying, and the full library is open to browse.

What is a batch, and why does it matter?

A batch is one production run of a material. One run can differ from the next, so a general certificate does not tell you much about the vial in front of you. We test each batch separately and publish that report with the product.

How do I know what is actually in the vial?

The report on the product page shows what the material is and how pure it is, along with the contamination checks, all from an independent laboratory.
