A 10-amino-acid kisspeptin fragment — a widely studied research peptide targeting the GPR54 (KISS1R) receptor.

Kisspeptin-10 is a synthetic 10-amino-acid C-terminal fragment of the kisspeptin protein encoded by the KISS1 gene. It is studied as a GPR54 (KISS1R) receptor agonist and is one of the more distinctive peptides in neuroendocrine research. Supplied as a lyophilized powder for laboratory research use.

First described in the late 1990s, kisspeptin has since become a widely referenced subject in published research and is one of the most studied peptides of its type. Manufactured in the USA and independently tested to ≥99% purity.

Why this one matters: Kisspeptin is one of the few commercially available peptides of its kind, which is part of why it is such a widely used reference compound in neuroendocrine research.

You ask, we answer

Everything you'd want to know about Aūra.

Verification, COAs, storage, handling — and what makes Aūra different. For research use only.

How are batches verified?
Independent third-party labs verify identity, purity, sterility, and endotoxins on every batch. Failed lots are rejected and never shipped.
Are COAs available?
Yes. Each shipment includes a batch-matched Certificate of Analysis tied to your specific lot number. Digital copies are also available through our COA library or by request.
What form will my peptides arrive in?
All Aūra peptides ship as lyophilized (freeze-dried) powder in sealed vials. Reconstitution instructions are provided with your shipment.
What purity specs do you follow?
≥99% purity confirmed via HPLC on qualifying batches. Mass verified via MS. All specs available on the batch-specific COA.
How should peptides be stored?
Store lyophilized vials at -20°C, protected from light. Once reconstituted, store at 2–8°C and use within the stability window noted on the COA.
Shelf life of unopened vials?
Unopened lyophilized vials are stable for up to 24 months when stored at recommended conditions. Exact shelf life is noted per batch on the COA.
What makes Aūra different?
Every batch is independently verified, lot-matched COAs ship with every order, and our verification standard rejects any batch that fails spec — no exceptions. Built for research labs that need reproducibility.
