Overview
Ecnoglutide, known in the development literature as XW003, is a long-acting glucagon-like peptide-1 receptor agonist analogue. Like other members of the class it is built on the GLP-1 backbone with substitutions that resist dipeptidyl peptidase-4 cleavage and a lipid side chain that promotes albumin association, together giving a much longer circulating profile than native GLP-1. What distinguishes it in published descriptions is the signalling profile: ecnoglutide has been characterised as cAMP-biased, meaning it favours Gs-coupled cAMP generation over beta-arrestin recruitment at the receptor.
We supply ecnoglutide as a lyophilized powder in 5 mg and 10 mg sealed vials, purified to ≥99% by HPLC and released with a lot-matched certificate of analysis. It ships from a United States facility and is intended exclusively for laboratory research.

Working out the concentration
Because Ecnoglutide arrives dry, its concentration is a decision rather than a specification. Run the numbers through the reconstitution calculator — vial mass in, diluent volume in, mg/mL and mass per syringe unit out.
Certificate of analysis
Every lot of Ecnoglutide is released against a certificate of analysis: the batch-specific laboratory data for that lot, not a generic document for the compound. The lot number on the certificate matches the lot number printed on the label you receive — the vial label itself, where the product is vialled — so the record and the material it describes can always be reconciled.
Purity: ≥99% by HPLC — the specification for this listing. The figure for the lot you receive is the one reported on that lot’s certificate.
No lot certificate is on display on this page at the moment. That is a publishing state and not a testing one: lots are released and documented as described above whether or not the document is posted here, and we will send what exists for the lot in stock, or for a lot already on your bench, by its number.
Certificates are available on request before you order as well as after, with no account and no charge. Request the certificate for this listing, read the testing and documentation policy in full, or see how to read a peptide COA.
Questions about Ecnoglutide
What is ecnoglutide?
Ecnoglutide, research code XW003, is a long-acting GLP-1 receptor agonist analogue. It carries the backbone modifications and fatty-acid acylation typical of the class, and published characterisations describe it as biased toward cAMP signalling at the receptor.
How does it differ from semaglutide?
Both are acylated mono-agonists at GLP-1R, but ecnoglutide has been reported to favour Gs/cAMP signalling with less beta-arrestin recruitment. Researchers use that difference to separate signalling-bias effects from receptor-coverage effects in comparative assays.
What purity and documentation are provided?
Each lot is purified to ≥99% by HPLC and released with a lot-matched certificate of analysis covering purity and identity. Provide the lot number printed on your vial and the COA will be supplied.
How should reconstituted ecnoglutide be stored?
Keep it at 2–8 °C, protected from light, and use it within the window your protocol specifies. Aliquoting before freezing at −20 °C avoids the freeze–thaw cycles that degrade acylated peptides fastest.
Can I buy ecnoglutide online for personal use?
No. This is a research chemical sold for laboratory use only.
