How do I place my first order?

Confirm you’re a qualified researcher (21+) and the catalog and lot-specific pricing unlock. Browse the catalog, add to cart, and check out. You’ll confirm the research-use acknowledgment as you order, and every order includes that lot’s Certificate of Analysis.

Do I need an account to order?

No. You can order as a guest. You’ll confirm you’re a qualified researcher (21+) before you shop, and we document research-use sales against that. Creating a free account is optional: it keeps your COAs and order history in one place, and new customers get 10% off their first order.

Lab quality that

Most vendors publish the purity number their own supplier gave them. Every row below is measured by an independent lab before the lot is cleared to ship.

Quality control

Independently tested, every batch.

Our US-based partner lab, an ISO/IEC 17025-accredited facility, runs identity, purity, endotoxin, microbial and heavy-metal assays on every batch. It is a second, independent pass over the manufacturer’s own results, and if the two disagree the lot never reaches the catalog.

Yes. We document research-use sales, so you’ll create a free account and confirm you’re a qualified researcher (21+) before checkout. It takes about a minute.

Every product is an ISO 17025-verified reference compound for in-vitro and laboratory research only. Not for human or veterinary use. Handle with standard lab PPE. They are not drugs, supplements, or cosmetics.

No. These are ISO 17025-verified reference compounds, not approved by the FDA for therapeutic, diagnostic, or veterinary use. We’re upfront about the regulatory category we sit in, and the ones we don’t.

Every lot is third-party tested by an independent, U.S.-based ISO 17025–accredited lab for identity (LC-MS) and purity (HPLC ≥99%). The full COA travels with every order. Deeper method detail is on our Quality page.

These are lyophilized research powders in sealed, lot-coded vials, not sterile-filled liquid preparations, so we don’t make a sterility claim. What every lot is screened for is endotoxin (LAL) and microbial contamination (PCR-based) before release. Your batch’s results are reported on the COA in your account.

Orders ship from our U.S. warehouse with tracked FedEx 2-day delivery. Orders placed before 5pm ET dispatch the same business day. We ship within the U.S. only.
