What is Dulaglutide, and what is it used for?
Recombinant fusion protein: two GLP-1 analogue peptides linked to a modified human IgG4 Fc fragment. Not a peptide in the sense the rest of this catalog uses the word.
Agonist at the GLP-1 receptor. The Fc fusion is the long-acting strategy — a large protein is cleared slowly by the kidney and is recycled through the neonatal Fc receptor, which extends circulating time by a completely different route from the albumin-binding acylation used by semaglutide.
An approved medicine, marketed as Trulicity, with an extensive clinical literature. Also used as a GLP-1 receptor agonist reference compound in preclinical research.
That a research vial under this name contains the same molecule as the licensed product. A recombinant fusion protein is manufactured in cell culture rather than synthesised, and identity and purity for such a product mean something different from what they mean for a synthetic peptide.

Where to buy Dulaglutide: what to check before you order from anyone
Where to get Dulaglutide, and how to buy Dulaglutide online
You can buy Dulaglutide online here with guest checkout; verified in-stock orders placed before 12 PM Pacific are dispatched the same day.
Before ordering Dulaglutide from anyone, us included, run the 5 checks on verifying a certificate; the first is that the report resolves on the laboratory's own site, and a seller who cannot pass them is asking for the trust a certificate exists to replace.
Dulaglutide guides and documentation
Written to answer the questions that come up around Dulaglutide specifically, what its paperwork should show, how it is handled, and how to judge a supplier selling it.
The full library, grouped by what you came to answer, is in the laboratory guides.
The Dulaglutide certificate: lot, purity, identity, and how to verify it
A certificate answers identity, purity and net content as three separate questions, each with the method that produced it and the date it was run, how to read one covers what each field does and does not cover. Dulaglutide is a GLP-1 analogue fused to an antibody Fc region, not GLP-1 itself. UniProt P01275 is the human precursor that native GLP-1 comes from, given for reference; the fusion is a larger glycosylated protein whose mass the lot certificate reports. So the mass on the lot certificate is the one to read; a listing that quotes the published figure for this material is quoting the wrong molecule.
Dulaglutide certificates post here and in the certificate index when Kovera Labs reports on the lot.

Is Dulaglutide a prescription drug? FDA status, and what this listing is
FDA status, and what this listing is Not an FDA-approved drug product
The FDA has not approved this compound for anything, and nothing in this catalog is a medicine.
Status verified 2026-08-25. Check the primary source before relying on this summary.
It is sold as laboratory material under the research-use restriction below. Being listed is not an approval, and not a claim that it is safe, effective or right for any purpose. LabFirst is not a pharmacy or a compounding facility, this vial is not a compounded medicine, and no prescription is involved, because it is not sold for use in anyone. Search results also show compound Dulaglutide and Dulaglutide compound offers from compounding pharmacies; a compounded Dulaglutide is a prescription product prepared for a named patient, and a certificate for this lot says nothing about one.
Dulaglutide research: what the published studies examine
Status: No FDA-approved application. This compound is sold as laboratory material. Where research on it has been published, it sits at the animal, cell or early-human stage, and this record does not summarize what it found. A supplier is not a neutral judge of evidence about its own catalog.
Dulaglutide is structurally the odd one out among the GLP-1 compounds on this catalog, and the difference is more than academic. Semaglutide is a synthetic peptide made long-acting by attaching a fatty acid that binds albumin. Dulaglutide is a recombinant fusion protein: GLP-1 analogue sequences covalently linked to a modified IgG4 Fc fragment, produced in cell culture rather than by solid-phase synthesis. The Fc portion extends its circulating life through slow renal clearance of a large molecule and recycling by the neonatal Fc receptor.
That has a direct consequence for anyone buying it as research material. A synthetic peptide has a defined sequence a mass spectrometer can confirm; a recombinant fusion protein carries glycosylation and charge heterogeneity that vary with the expression system, so identity and purity testing is a materially different and harder exercise, and a purity number produced by peptide HPLC does not mean for this molecule what it means for semaglutide.
| Reported observation | Model | Source |
|---|---|---|
| Used as a long-acting GLP-1 receptor agonist in a rodent study of antipsychotic-induced metabolic effects, dulaglutide is characterized as a recombinant fusion protein of GLP-1 analogue with an immunoglobulin Fc fragment. In that model dulaglutide alone produced only a modest decrease in food intake with no effect on weight gain and did not reverse olanzapine-induced serum lipid changes; the effect appeared only in combination with food restriction. | Sprague-Dawley rats, 8-day olanzapine model with pair-feeding protocol | Horska and colleagues, Potent synergistic effects of dulaglutide and food restriction in prevention of olanzapine-induced metabolic adverse effects in a rodent model, Biomedicine and Pharmacotherapy (2024)Academic, not sponsor work. Notable that the compound alone did not move weight in this model — an unflattering result that supplier summaries would not carry. |
| For contrast within the same receptor class, the acylation strategy used by semaglutide achieves long duration by a different route: two amino acid substitutions plus a fatty diacid at lysine 26 producing strong albumin binding, with a plasma half-life of 46.1 hours in mini-pigs and GLP-1 receptor affinity of 0.38 nM. | receptor binding, crystallography and mini-pig pharmacokinetics | Lau and colleagues, Discovery of the once-weekly glucagon-like peptide-1 (GLP-1) analogue semaglutide, Journal of Medicinal Chemistry (2015)Cited to contrast two different long-acting strategies within the same receptor class. |
Open questions. Dulaglutide is an approved medicine with a large clinical literature, and this page does not reproduce its efficacy endpoints for the same reason the other incretin pages do not. The distinctive issue here is manufacturing rather than pharmacology. The licensed product is a recombinant fusion protein made in a controlled cell-culture process with full release testing behind it, including tests for glycosylation, aggregation and host-cell protein content that have no counterpart in synthetic peptide manufacture.
A research vial sold under this name cannot be assumed equivalent, and the standard analytical package for a peptide does not answer the questions a fusion protein raises. Anyone comparing suppliers on this item should ask what the expression system was and what the certificate actually measured, because purity by peptide HPLC would be close to meaningless here. This page does not reproduce clinical efficacy endpoints.
That is a deliberate and consistent choice across every incretin compound on this catalog: those results describe a supervised therapy given to patients under medical care, which is a different thing from laboratory material, and printing them beside a purchase control would blur that distinction rather than inform anyone. Tolerability findings from the same trials are reported, because how often a compound causes adverse events is a property of the compound.
Finally, the point that applies to every reseller including this one: a vial bearing one of these names is related to the developed molecule by claimed sequence identity alone, and that claim is exactly what an identity assay on the specific lot exists to test.
Each row above describes an observation in the stated model. None of it describes what Dulaglutide would do in a person or an animal outside that model, and none of it is a recommendation to use it for anything.
How to store Dulaglutide: refrigeration and shelf life
Keep the sealed vial cold and out of the light and it stays as it left the lab. Once it is mixed into a solution, how long it holds up depends on the compound, what it was mixed with, how strong the solution is and how cold it is kept — too many variables for anyone to print one shelf life on a label. So laboratories write the date on whatever they prepare and keep their own record of it.
For solution preparation arithmetic on the bench, concentration, per-graduation values and molarity, use the vial concentration calculator, which opens with the Dulaglutide sizes stocked here already loaded. It covers laboratory measurement only and contains no administration guidance.
