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 catalogue 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.
Dulaglutide for sale: 5mg and 10mg vials, price per mg
Dulaglutide cost, and Dulaglutide price per mg by size
Dulaglutide is sold in 2 sizes here, 5mg and 10mg, from $130.00 a vial. Dulaglutide cost starts at that figure for the smallest vial, and the Dulaglutide price per mg in the second column is the number to compare between sizes. The per-mg column is the honest comparison between sizes; the two tier columns show what ten and twenty vials of one size bill at, because the volume discount is per size and mixed sizes do not combine.
| Size | One vial | Per mg | 10 vials −10% | 20 vials −15% | Availability |
|---|---|---|---|---|---|
| Dulaglutide 5mg | $130.00 | $26.00 | $1,170.00$23.40/mg | $2,210.00$22.10/mg | Backordered — waitlist |
| Dulaglutide 10mg | $135.00 | $13.50 | $1,215.00$12.15/mg | $2,295.00$11.47/mg | Backordered — waitlist |
Dulaglutide discounts: bulk pricing, Subscribe & Save, and codes
Three things move this price and nothing else does: how many vials of one size are on the order, whether that order repeats, and one code. The fourth column prices each route against the 5mg vial.

The first three stack; the codes do not. A volume discount comes off the line, a subscription cadence comes off that same line from shipment 2, and one code comes off what is left. One code per order, never two. A subscription runs a minimum of two shipments and can be cancelled once the second has shipped, and the first shipment always bills at today's eligible price with no cadence discount on it. The lowest this record ever bills is $20.77 per mg: twenty 5mg vials on a monthly subscription, from shipment 2 onward.

Where to buy Dulaglutide: five checks 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.
Run these on us too. A supplier who cannot pass them is asking you to take their word for it, and their word is the one thing a certificate exists to replace.
- Check the certificate on the lab’s own site, not ours.
- See whether it was written for the seller.
- Match the lot number on the paper to the one on the vial.
- Look for a method and a date next to every number.
- Make sure identity was tested, not assumed.
Each of those is worked through, with what a failed check actually looks like, on verifying a certificate.
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.
The certificate below belongs to one lot, and its number matches the one printed on the vial you receive. A real report for a different batch is still the wrong report.
| Size | Lot | Identity method | Purity | Test date |
|---|---|---|---|---|
| 5mg | Pending verification | Pending verification | Pending verification | Pending verification |
| 10mg | Pending verification | Pending verification | Pending verification | Pending verification |
No lot documentation is published for Dulaglutide yet. Rather than display a placeholder certificate, this record shows the gap until each field has been verified against the lot in hand. The certificate index lists every lot the moment its report clears.

Is Dulaglutide a prescription drug? FDA status, and what this listing is
The FDA has not approved this compound for anything, and nothing in this catalogue is a medicine. Where a compound stands legally depends on what it is, what form it is in, what it is being used for and which country you are in, and it changes over time, so the status shown here carries the date it was last checked.
Status verified 2026-08-25. Regulatory positions move; check the primary source before relying on any summary, including this one.
It is sold here as laboratory material under the research-use restriction that closes this page, which is not an approval, and not a statement that the compound 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 summarise what it found. A supplier is not a neutral judge of evidence about its own catalogue.
Dulaglutide is structurally the odd one out among the GLP-1 compounds on this catalogue, 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 characterised 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 catalogue: 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.
