Ecnoglutide — XW003 in development papers — is a long-acting analogue that activates the glucagon-like peptide-1 receptor. As with others in its class, it is built on the GLP-1 sequence with changes that protect it from dipeptidyl peptidase-4 and a fatty side chain that encourages albumin binding, which together keep it in circulation far longer than native GLP-1. What sets it apart in the published descriptions is how it signals: it is characterised as cAMP-biased, favouring Gs-coupled cAMP production over beta-arrestin recruitment at the receptor.
Ecnoglutide is supplied as lyophilised powder in sealed 5 mg and 10 mg vials, HPLC-purified to ≥99% and released with a certificate of analysis for the lot. It is dispatched from our EU warehouse and sold exclusively for laboratory research.

Questions about Ecnoglutide
What is ecnoglutide?
A long-acting GLP-1 receptor agonist analogue with the research code XW003. It carries the class's typical backbone changes and fatty-acid acylation, and published work describes it as preferring cAMP signalling at the receptor.
How does it compare with semaglutide?
Both are acylated single agonists at GLP-1R, yet ecnoglutide is reported to favour Gs/cAMP signalling while recruiting less beta-arrestin. Comparative assays exploit this to separate the effects of signalling bias from those of receptor coverage.
What purity and documents come with it?
Every lot is HPLC-purified to ≥99% and released with its own certificate of analysis for purity and identity. Tell us the lot number on your vial and we will send the matching COA.
How is reconstituted ecnoglutide stored?
At 2–8 °C, protected from light, for no longer than your protocol allows. Divide it into aliquots before freezing at −20 °C to spare it the freeze–thaw cycles that damage acylated peptides most quickly.
Can I purchase ecnoglutide for personal use?
No. It is a research chemical, sold only for use in the laboratory.
