Method
Quality and testing
How a lot earns its way out of the lab
Six steps from raw material to sealed vial. A lot that misses the purity floor is rejected, never blended down to meet it.
-
Raw-material verification
Incoming amino-acid derivatives and reagents are checked for identity and purity before they enter production.
-
Controlled synthesis
Peptides are assembled by solid-phase synthesis under controlled cleanroom conditions with in-process checks.
-
Purification
Crude product is refined by reverse-phase HPLC until it meets the release specification.
-
Analytical confirmation
Finished lots are analyzed by HPLC for content and by mass spectrometry for identity, including an independent pass at our Los Angeles testing laboratory.
-
Documentation
A Certificate of Analysis is generated for the lot, with batch records retained for full traceability.
-
Sealed packaging
Lyophilized product is filled into sterile vials, sealed, and held in climate-controlled storage until dispatch.
Ordering
What happens after you check out
Free U.S. shipping over $100
Tracked with every carrier we use. Under the threshold you pay the carrier rate shown at checkout, never a handling markup.
Nothing on the box says what is in it
Vials ship sealed, cushioned and boxed, with insulation added when transit conditions warrant it. The outside carries no reference to the contents.
Transit damage is replaced once, free
Send photos within 14 days of delivery and a replacement ships. Sealed research material cannot be returned, so this is the cover that replaces a returns window.
Sourced, tested and shipped in the U.S.
Sourcing, quality control and fulfilment all run domestically under documented procedures, with batch traceability from lot to vial.

Answers
Questions researchers ask first
The ones that come up before a first order. Everything else is on the FAQ page, and support answers within one business day.
Orders are processed within 0–2 business days. Standard U.S. delivery typically takes 3–5 business days after dispatch, and expedited options are available at checkout.
Every batch is held to a ≥99% purity target verified by HPLC, with identity confirmed by mass spectrometry. Batches that miss the standard are rejected, not discounted.
Certificates are available on request. Email support with the lot number printed on your vial and we’ll send that lot’s certificate, usually the same business day. Here is how to request one.
Our products are laboratory reagents, not drugs, foods, cosmetics, or supplements. They may only be used for in-vitro research and laboratory experimentation by qualified individuals, and never on humans or animals. Every order requires attestation to our research-use policy.
Yes. Research institutions and high-volume buyers can request a custom quote through the contact page. Include the compounds and quantities you need.
For product integrity reasons we can’t accept returns, but orders are protected against transit damage: report damage with photos within 14 days and we’ll ship a one-time replacement. Full details in the returns policy.

Every lot has a certificate of analysis on request
Held on file per lot and emailed on request, usually the same business day. Send the lot number from your vial and we will send that lot’s report.
How to request one -
Two independent analyses before a vial is released
HPLC for purity against a ≥99% target and mass spectrometry for identity. A lot that misses either one does not ship.
