Peptides you can
actually verify.

It's the area percentage of the main peak in an RP-HPLC chromatogram, measured against every other detected species in the sample. A 99.8% result means that under the stated method, 99.8% of the detected material eluted as the target peptide. We publish the method, gradient and retention time alongside the number so it can be independently reproduced.

No. Everything we sell is supplied strictly for laboratory and research use, and is not approved by the FDA for human or veterinary administration. We don't provide medical advice, dosing guidance or clinical supervision. If you're considering a GLP-1 therapy for your own health, speak to a licensed clinician about a prescribed, pharmacy-dispensed product.

Lyophilized vials are stable at 2–8 °C and should be kept refrigerated, protected from light. For long-term storage beyond a few months, −20 °C is preferable. Once reconstituted, peptides are substantially less stable — keep them refrigerated and consult the stability window printed on the product's technical sheet.

Yes — that's the point of the batch ID. Enter the lot number printed on your vial into the batch lookup above and you'll get the exact report generated for that synthesis run, including the raw chromatogram. Reports are also cryptographically hashed at publication, so any later edit is detectable.

Every shipper contains an irreversible temperature indicator. If it has tripped on arrival, photograph it and contact support — we'll reship the entire order at our expense, and you don't need to send anything back. This applies regardless of whether the carrier or we were at fault.

Major credit and debit cards, ACH bank transfer for research accounts, and selected cryptocurrencies. Card data is handled entirely by PCI-DSS certified processors — it never touches our infrastructure. Research accounts can also be set up on Net-30 terms with a purchase order.

We ship to all 50 US states as standard, with 2–3 day express cold-chain. Selected international lanes are available on request for research accounts, subject to the destination country's import rules — which are your responsibility to confirm before ordering.
