Every Peptide, Verified Before It Ships.
Research compounds tested for identity and purity before they are listed. Each lot's certificate is published under its own lot number, so you can read the data behind the vial you receive.
Research Compounds
Read the Paperwork First.
Every lot ships with a signed certificate of analysis — identity confirmed, purity assayed — published under its lot number before the compound is listed, and archived permanently in your account after purchase.
Two ways to find one: search the lot number on your vial, or browse the catalog by category, product and variant to see current and historical documentation.

Built Around Quality. Backed by Transparency.
Three standards hold on every order: what we test before listing a lot, how that order reaches you, and the documentation you can read for yourself.
Quality You Can Verify
Identity is confirmed by mass spectrometry and purity by reverse-phase HPLC before a lot is listed, with a retained sample sent to an unaffiliated second lab. Both certificates are published against the lot.
How We TestHandled with Care
Orders ship in plain, unbranded, tamper-evident packaging, tracked door to door. Completed, fully paid orders go out within one business day.
Shipping DetailsKnow Your Lot
The lot number on your vial resolves to one certificate in COA Lookup, current and historical documentation included. If material doesn't match the certificate published for its lot, we replace it or refund it.

Questions,
Answered.
Is Every Lot Really Tested?
Yes. Identity is confirmed by mass spec and purity by reverse-phase HPLC, and a retained sample goes to a second, unaffiliated lab. Both certificates are published against the lot number before the product page goes live.
How Do I Find the Certificate for My Vial?
Enter the lot number printed on the vial label into the COA lookup. The same certificate is archived permanently in your account after purchase.
How Fast Do Orders Ship?
Completed, fully paid orders ship within one business day from our U.S.-based fulfillment center, FedEx with tracking. Expedited options are available at checkout for an additional fee.
Is the Packaging Discreet?
Yes — plain, unbranded, tamper-evident outer packaging. Nothing on the outside identifies the contents or the sender category.
How Should Material Be Stored?
Compounds ship as lyophilized powder, shelf-stable and sealed, so no cold chain is required in transit. For long-term storage keep lyophilized at −20°C away from light.
Can These Be Used in Humans or Animals?
No. Everything sold here is strictly for in-vitro laboratory research. These are not drugs, foods, cosmetics or supplements, and are not for human or veterinary use.
