Frequently asked questions.
What is GLP-3R?
GLP-3R is a synthetic research peptide characterized in vitro at the GIP, GLP-1, and glucagon receptors. Excalibur Peptides supplies it as a lyophilized research chemical for receptor-binding and signaling research in the laboratory only.
Where can I buy GLP-3R for research?
Excalibur Peptides sells GLP-3R on this page as a 10mg vial of lyophilized powder, for in-vitro laboratory research only. Orders ship from Austin, Texas, to addresses within the United States, and the product's third-party Certificate of Analysis is published in our COA database. Buyers must be 21 or older and confirm research-use-only status at checkout.
How is GLP-3R tested, and where is its COA?
GLP-3R is third-party tested by Freedom Diagnostics Testing: purity by HPLC and identity by LC-MS. The Certificate of Analysis is published in our COA database, and the report can be looked up on the lab's own site with search code Exca2610050656.
How should GLP-3R be stored in the lab?
Keep lyophilized GLP-3R sealed at 2–8 °C, protected from light and moisture, as listed on this page. Let the vial reach room temperature before opening so moisture does not condense on the powder, and avoid repeated freeze–thaw cycles.
How fast does GLP-3R ship?
GLP-3R ships from Austin, Texas. Orders placed before 2 PM EST on a business day ship the same day, and delivery within the United States typically takes 2–4 business days. A tracking number is emailed when the order ships.
What payment methods can I use to buy GLP-3R?
We accept credit and debit cards, Apple Pay, Venmo, Cash App and cryptocurrency. Prices are in U.S. dollars.
Is GLP-3R approved by the FDA?
No. The GLP-3R supplied by Excalibur Peptides is not approved by the FDA for human or veterinary use. It is sold only for in-vitro laboratory research and identification purposes and is not for human consumption.
For research and laboratory use only. Not for human consumption.
