Frequently asked questions

This site is a catalogue, not a checkout. Send us the compound name, vial size and quantity through the contact form, and we will reply with availability, current pricing and the documentation for the lot in stock. Once you confirm, we issue an invoice and dispatch on receipt or on approved terms.

There is no minimum for standard catalogue items. For bulk quantities, custom fill volumes or gram-scale requirements, contact us — those are quoted individually.

We supply research institutions, universities, contract research organisations and independent researchers. Materials are sold strictly for laboratory research and development. We do not supply product for personal consumption, and we cannot give dosing, medical or veterinary advice.

Yes. Ask for the current lot's certificate through the contact form and we will send the PDF for the lot that would ship to you. Every order also includes the certificate for the exact lot supplied.

An accredited independent laboratory. We do not test in-house and we do not present our own measurements as third-party verification. The certificate reproduces their chromatogram and mass-spectrometry result.

Most catalogue compounds are released at ≥ 98.5% by RP-HPLC, with the majority at ≥ 99.0%. The exact specification for each compound is shown on its product page, and the measured value for your specific lot is on its certificate.

Standard catalogue items dispatch within one to two business days. US domestic shipments are tracked. If you have a deadline, tell us when you enquire and we will confirm feasibility before you commit.

Lyophilised peptides are stable at ambient temperature for the duration of normal transit, so standard tracked shipping is appropriate. Packaging is discreet, with no indication of the contents on the outer label. If you require cold-chain shipping, say so when ordering.

Store lyophilised powder at −20 °C, protected from light and moisture. Let the vial equilibrate to room temperature before opening to avoid condensation. Once reconstituted, keep at 2–8 °C and use within the period stated on the datasheet — typically 30 days.

No. All products are supplied for laboratory research use only. They are not approved medicines, foods, cosmetics or dietary supplements, and are not intended for human or veterinary use. Nothing on this site is a claim of diagnostic or therapeutic benefit.

We keep only the information needed to answer your enquiry and fulfil your order, we never sell it, and we do not add you to marketing lists without consent. See our privacy policy for the detail.
