Questions we can answer — and the ones we can't

It means every item we sell is a laboratory reference chemical intended for in-vitro research and analytical work. The materials are not drugs, supplements, foods, cosmetics, or medical devices, and they must never be administered, ingested, injected, inhaled, or applied to a human or an animal.

No. We do not provide dosing, protocol, or administration guidance of any kind, and our team is not permitted to discuss human or veterinary use. Requests for that information are declined, and orders may be cancelled.

Purchasers must be 21 or older and must be a qualified researcher or buying on behalf of a research institution such as a university, hospital, CRO, or analytical laboratory. A research-use attestation is required at checkout.

Each lot is screened by mass spectrometry to confirm identity and quantified by reverse-phase HPLC for purity as an area-percent value. Lots below the catalog specification for a listing are rejected rather than re-graded.

Yes. Certificates are lot-matched to the number printed on your vial and include the test method, dates, and issuing laboratory. A COA describes chemistry only — it is not a sterility or fitness-for-use statement.

Lyophilized vials should move to -20 °C storage, protected from light, promptly after inspection. Material in solution is materially less stable. Storage, handling, and disposal are the purchaser's responsibility.

No. Research chemicals are not reviewed by the FDA for safety, effectiveness, or manufacturing quality. No statement on this site has been evaluated by the FDA, and nothing here is intended to diagnose, treat, cure, or prevent any disease.

A research-use label does not change what a material legally is. Peptides that are, or are close analogs of, approved or investigational human drugs are treated as unapproved new drugs regardless of how they are labelled, so we do not stock them. Our catalog is limited to synthetic peptides and labware supplied for in-vitro characterization.

No. We stock only glassware, pipette tips, and metrology equipment used for weighing, aliquoting, and analysing material at the bench. We do not supply anything intended to prepare or deliver an injection.

The purchaser does. Once material is delivered to the U.S. forwarding address you provide, any onward movement is an export you arrange and control, including import permits, customs declarations, duties, and any restriction that applies to a listed material in your own country. We do not ship to a forwarding address when we have reason to believe onward movement would be unlawful.

All catalog prices, shipping charges, and refunds are stated and settled in U.S. dollars. Your card issuer applies its own conversion rate and any cross-border fee; we do not control or estimate those charges.

Because these are temperature-sensitive research materials, unopened vials may be returned within the window described in our refund policy when the seal and cold-chain packaging are intact. Opened vials cannot be returned.

We ship only to a mail-forwarding or freight-forwarding address inside the United States. Most of the laboratories we supply in Latin America maintain a U.S. forwarding mailbox and consolidate shipments from there. We do not ship directly across borders, and we do not act as exporter of record.
