Tirzepatide

Tirzepatide for research (LY3298176): one peptide, two receptor targets

Tirzepatide is a synthetic peptide made for laboratory research, coded LY3298176. (A peptide is a short chain of amino acids, the small building blocks that join to form proteins.) What makes it stand out is that one molecule acts on two receptors at once, the GIP receptor and the GLP-1 receptor. A receptor is a docking point on a cell, and a molecule that switches one on is an agonist; because Tirzepatide switches on two at once, it is a dual agonist. HerGlowLabs ships it as a lyophilised (freeze-dried) powder in a sealed vial, for in-vitro study only (work in glassware or cell cultures, never in a living body).

What makes Tirzepatide a dual agonist?

Tirzepatide is a peptide, not a steroid. Its backbone is a single chain of 39 amino acids, produced in the lab rather than taken from a natural source. It activates two incretin receptors together. Incretins are gut hormones released around mealtimes that help regulate blood sugar and energy, which is why Tirzepatide is a useful tool for studying how those two receptor pathways respond.

How Tirzepatide behaves at the GIP and GLP-1 receptors

Tirzepatide started as a reshaped version of GIP (glucose-dependent insulinotropic polypeptide, one of the gut’s incretin hormones), engineered so the same molecule also switches on the GLP-1 (glucagon-like peptide-1) receptor. In lab binding and signalling studies (its mechanism of action, how a molecule attaches to a receptor and passes its message along), it is a powerful agonist at the GIP receptor, roughly on par with the body’s own GIP, while its pull on the GLP-1 receptor is milder. To watch how the response shifts when a third target is added, teams often study it alongside Retatrutide, a triple agonist that acts on three receptors at once. These comparisons are done on the bench, never in humans or animals.

Approval status: a research compound, not a medicine

The Tirzepatide sold here is investigational, meaning it is still under study and has not been cleared as a finished product for sale or use. Neither the TGA (the Therapeutic Goods Administration, Australia’s medicines regulator) nor the FDA has approved it for the purpose shown here. It is not a medicine, a supplement, a cosmetic, or a consumer product of any kind; it is supplied only as a material for laboratory research.

How Tirzepatide is used in the laboratory

In the lab, Tirzepatide serves as a reference research chemical for looking at how the incretin receptors pass on their signals, and it belongs to the HerGlowLabs Metabolic Research range. For contrast, a study may place it beside a peptide from another family, such as Cagrilintide, an amylin analogue (a molecule that mimics amylin, a separate hormone linked to blood-sugar and energy balance). Comparing a GIP/GLP-1 agonist with an amylin-based compound shows how two different receptor systems respond. All of this stays strictly in-vitro.

Purity, Janoshik testing and the Certificate of Analysis

Every HerGlowLabs batch goes to Janoshik, an independent third-party laboratory, before it reaches the shop. Purity is read by HPLC (high-performance liquid chromatography, which separates a sample so the share of the target compound can be measured) and comes in above 99%, latest batch 99.9%, and a blind identity test against other GLP-1 peptides returns the sample as Tirzepatide. The matching Certificate of Analysis (CoA, the lab’s report for that batch) is posted on the HerGlowLabs lab test page, so you can check each vial against its own results before ordering.

Buy Tirzepatide in Australia and New Zealand: vials and bulk

• Tirzepatide is available for sale online in Australia and New Zealand, direct from HerGlowLabs, in 10mg and 20mg vials.
• Scaling up a study? The 10x Tirzepatide bulk multipack brings down the price per vial.
• Orders are sent across Australia and New Zealand by tracked Australia Post Express.

How to store and reconstitute Tirzepatide

• Keep sealed vials away from light and heat: below 25°C for short periods, or about -20°C in a freezer for longer storage.
• To make a working solution, reconstitute the powder (dissolve it into liquid) with sterile or bacteriostatic water (water with a mild preservative that holds back bacterial growth).
• Keep the mixed solution refrigerated, and do not put it through repeated freeze-thaw cycles, which can break the peptide down.

Common questions about Tirzepatide

What is Tirzepatide (LY3298176)?

Tirzepatide is a synthetic research peptide and a dual agonist, meaning one molecule switches on both the GIP and the GLP-1 receptor. LY3298176 is the development code it is listed under, and HerGlowLabs supplies it as a lyophilised powder for in-vitro laboratory research.

Is Tirzepatide a peptide, or is it a steroid?

A peptide. It is a chain of 39 amino acids and is not a steroid; the two are built differently and work through different routes.

Is Tirzepatide a GIP agonist or a GLP-1 agonist?

Both at the same time. A single Tirzepatide molecule activates the GIP receptor and the GLP-1 receptor together, and acting on two targets at once is exactly what a dual agonist does.

How pure is Tirzepatide, and is a Certificate of Analysis included?

Each batch is tested by Janoshik, an independent lab, and comes in above 99% by HPLC, with the latest batch at 99.9%. A blind identity test confirms the sample is Tirzepatide. The batch Certificate of Analysis (CoA) is available on the HerGlowLabs lab test page.

How should Tirzepatide be stored and reconstituted?

Keep sealed vials below 25°C for short spells, or near -20°C for longer storage, away from light. To prepare a solution, reconstitute with sterile or bacteriostatic water, refrigerate it after mixing, and avoid repeated freeze-thaw cycles.

Can I buy Tirzepatide in Australia and New Zealand, and which vial sizes are sold?

Yes. HerGlowLabs sells Tirzepatide online across Australia and New Zealand in 10mg and 20mg vials, with a 10x bulk multipack for larger projects, sent by tracked express post.

What does the milligram figure on the vial mean?

The milligram figure, 10mg or 20mg, is simply how much peptide powder is sealed inside the vial. It is a laboratory quantity, not a dose, because the product is not for human or animal use.

Is Tirzepatide approved for human or medical use?

No. It is an investigational research compound and has not been approved by the TGA or FDA for the use sold here. It must never be used in humans or animals.

Disclaimer: Tirzepatide is supplied strictly for in-vitro laboratory research. It is not a medicine, supplement, or cosmetic, and it is not for human or animal use. By placing an order, you confirm that you are a qualified researcher and that you will handle and use the product in line with all applicable laws.
