GLP-III 5mg
GLP-III (LY3437943) is a synthetic single-molecule triple agonist targeting the GIP, GLP-1, and glucagon receptors simultaneously. It is among the most-studied next-generation metabolic research peptides.
GLP-1 receptor activation potentiates glucose-dependent insulin secretion and slows gastric emptying; GIP receptor activation modulates adipose and insulin signalling; and glucagon receptor activation increases energy expenditure and hepatic lipid mobilisation. The combined agonism is investigated in preclinical models of body-weight regulation, glucose homeostasis, and hepatic steatosis.

Where can a laboratory buy GLP-III in the EU?
Onyx Peptides supplies GLP-III for laboratory research across the European Union. We are operated by Vexio j. s. a. (IČO 54214530) in Slovakia and dispatch from within the EU, so there is no customs entry, no import duty and no border hold. Orders placed before 16:00 CET ship the same day, and shipping is free above €100.
How do I verify the batch of GLP-III I receive?
Each vial carries a batch number. Ask us for the Certificate of Analysis of the batch currently in stock — before you order, not after — and check that the batch number on the certificate matches the one printed on the vial. The analysis is performed by Janoshik Analytical, an independent laboratory in Prague, which will confirm a report it issued if you contact them with its identifier.
How is purity verified?
Every batch is independently tested by Janoshik Analytical using HPLC and Mass Spectrometry. A batch-specific Certificate of Analysis — also covering endotoxins and heavy metals — is available on request.
How fast is delivery?
We dispatch from within the EU, same day on orders placed before 16:00 CET. EU delivery typically takes 1–3 business days.
What payment methods do you accept?
We accept SEPA bank transfer (−2 %), cryptocurrency (−5 %), cash on delivery (+€1.50). Bank-transfer orders are dispatched as soon as the payment clears; SEPA instant transfers usually arrive within seconds.
How should this be stored?
Store at 2–8 °C, protected from light. Once reconstituted, keep refrigerated and use within 30 days.
What is the intended use?
All products are supplied strictly for in-vitro laboratory and research use only. They are not for human consumption, veterinary, or clinical use.
