Questions, answered
without the hedge.

Qualified researchers and research organisations, aged 21 or over, purchasing for in-vitro laboratory work. Placing an order confirms you meet those conditions. We decline orders at our discretion.

Pricing depends on lot and quantity, and we quote it directly rather than publishing a number that changes. Request a quote from any product page and you will have an answer within one business day.

The certificate is the sample. It tells you the purity, identity, net peptide content and moisture of the exact lot you would receive — which is considerably more informative than a small quantity of it.

An independent laboratory that is not owned by us, not paid by result, and named on every certificate. In-house testing by a supplier is a self-assessment, and we do not treat it as evidence.

Main-peak area over total integrated area by reverse-phase HPLC with UV detection at 214 nm. It is a chromatographic purity figure. It is not a statement about net peptide content, moisture, sterility, or endotoxin — each of which we report separately or explicitly decline to claim.

Yes. A failed lot is marked withheld, is not sold, and its certificate stays online. A supplier whose archive contains only passes is showing you an edited record.

The catalog figure is a minimum specification; the certificate is the measurement for your lot. The certificate governs. If a lot measured below the catalog minimum it would not have been released to you.

Almost certainly not. Lyophilized peptide is stable for several days at ambient temperature — the cold pack is a margin of safety, not a requirement of transit. Transfer the vial to −20 °C, desiccated and light-protected, on receipt.

Lyophilized and sealed: −20 °C, desiccated, protected from light. Storage conditions specific to each compound are stated on its product page and on the handling sheet shipped with the order.

We publish laboratory solvent compatibility on each product page. We do not publish reconstitution protocols, volumes, or any procedure oriented toward use in humans or animals, and our staff will not provide them.

That the material is a chemical reference standard for in-vitro laboratory research. It is not a drug, supplement, food, cosmetic or medical device; it is not intended to diagnose, treat, cure or prevent anything; and it is not for human or veterinary administration by any route. This is a condition of sale, not a formality.

No — and not as a legal hedge. We do not hold that information in a form we would stand behind, and providing it would misrepresent what this material is. Repeated requests will result in cancellation.

That depends entirely on where you are, and it is your responsibility to establish. Regulatory classification of these compounds varies by country and changes over time. We do not provide legal advice, and we will not mis-declare a shipment to assist a customs outcome.
