About Astra Peptides
Verified purity.
Here’s the COA.
Astra Peptides is a US-based research-compound supplier serving researchers who refuse to compromise on what's in the vial. Every batch is independently tested by an independent laboratory, every order ships with a Certificate of Analysis tied to its lot, and our compounds hold a single standard: ≥99% purity, typically 99.5%+.
Our standard
The research-peptide market is crowded with brands that claim purity but rarely show it. We do it the other way around.
Before any compound leaves our facility, it is independently verified — not by us, but by an outside laboratory whose name we put on every batch.
Every vial we ship is prepared in the United States, third-party tested by an independent laboratory, and accompanied by a verifiable Certificate of Analysis tied to its specific lot. If quality is the question, the document is the answer.
What we stand for
Three things,
without exception.
01 / Purity
Purity
Every batch is independently verified to ≥99% purity — typically 99.5%+, confirmed by HPLC and HPLC identity testing. Built for serious research, not for cutting corners.
02 / Transparency
Transparency
A Certificate of Analysis on every batch, tied to its specific lot number and summarizing the full purity results. Read the data before you buy — the COA Library is open.
03 / Integrity
Integrity
We don't make claims we can't substantiate, and we don't cut corners on what matters. Testing is independent, documentation is verifiable, and everything we sell is strictly for research use.
How we test
A full purity
analysis. Every batch.
Every batch is sent for an independent HPLC purity analysis — a comprehensive battery of tests covering identity and purity alongside the safety and quality markers researchers rely on. Rather than a single spot-check, the purity builds a full profile of the material before it ever leaves the facility.
Identity is confirmed by HPLC. Purity is measured by HPLC. The results for each batch are summarized on its Certificate of Analysis, tied to a real lot number we can produce on demand.
By the numbers
Substantiated, not stated.
Standards mean nothing if they aren't measured. These are the figures every batch is held to, verified by an independent laboratory.

Where we operate
Made in the
United States. By choice.
Astra Peptides operates inside the US life-sciences ecosystem — one of the densest concentrations of pharmaceutical, life-sciences, and analytical-chemistry expertise in the world. It is not an accident that we are here.
Operating in the United States means our supply chain is auditable. It means the laboratory we work with answers to the same regulatory frameworks our customers do. It means a lot number printed on a vial corresponds to a real document we can produce on demand.
It is more expensive to operate this way. That cost is built into our pricing, and we make no apologies for it.
