Catalog
Featured compounds
The full catalogue holds every compound and size.
Standards
Made, tested, documented
How each lot is synthesized, assayed, and recorded before it reaches your bench.

United States manufacturing
Synthesized and lyophilized in the United States under cleanroom protocol.

Independent verification
Every lot is HPLC- and MS-verified by an independent contract laboratory.

Certificate with every lot
Each figure traces back to a signed certificate bound to the lot identifier.
Process
How a lot reaches you
Four steps from synthesis to release, with an independent assay in the middle.
- 01
Synthesis
USA · Audited facility
Peptides are built by solid-phase synthesis under cleanroom protocol. Every crude product is entered against a unique lot identifier in the format HRL-YYWW-xxxN.
- 02
Lyophilization
Sealed amber glass · Inert atmosphere
The material is dried under vacuum and sealed in amber glass under inert gas. Once sealed it is stable at ambient temperature, and each vial is labelled with its lot, fill mass, and synthesis date.
- 03
Independent assay
HPLC + MS · Third-party
A representative sample from every lot goes to an independent contract laboratory, which quantifies purity by HPLC and confirms molecular weight by mass spectrometry.
- 04
Certificate release
Lot-linked
A signed certificate is tied to the lot identifier and made available with the order before any shipment leaves the facility.
Common questions
