Product Information

Two Signals. One Goal. More Results Than Semaglutide Alone.

Tirzepatide (20mg) is available in Australia through Aus Peptide Supply with fast domestic shipping to all states and territories.

Semaglutide — the compound behind Ozempic and Wegovy — works by activating one receptor: GLP-1. Tirzepatide does the same, but adds a second signal at the same time, activating the GIP receptor alongside it. That dual action is why Phase 3 trials recorded average weight reductions of up to 22.5% over 72 weeks — one of the largest figures ever documented in weight management research. It's more than semaglutide's trials produced, and it set the benchmark that newer compounds like Retatrutide are now being measured against.

Tirzepatide works by telling your body two things at once: reduce your appetite, and improve how you handle blood sugar and insulin. It slows gastric emptying so you feel full for longer, dials down hunger signals in the brain, and helps stabilise blood glucose — all at the same time. The result is less food consumed, better metabolic efficiency, and more body fat used as fuel.

What Tirzepatide Is Studied For

  • Significant Fat Loss — Up to 22.5% body weight reduction over 72 weeks in Phase 3 trials — among the largest ever documented in this research category
  • Appetite Suppression — Reduces hunger and food intake by slowing digestion and modulating hunger signals in the brain
  • Blood Sugar Control — Studied for improving insulin sensitivity and HbA1c levels, relevant to metabolic health and type 2 diabetes research
  • Body Composition — Studied for preferential reduction in body fat rather than lean mass
  • Cardiometabolic Health — Investigated for improvements in blood pressure, cholesterol, and cardiovascular risk markers alongside weight loss
  • Liver Fat — Emerging research on reduction of fatty liver markers and NASH-related changes

Supplied as lyophilized powder, verified by HPLC and mass spectrometry. 20mg per vial. Fast domestic shipping across Australia, with batch-specific CoA information available in our CoA Library.

Frequently Asked Questions

What is Tirzepatide?
Tirzepatide is a weight management peptide that activates two hunger and metabolism receptors at once — GLP-1 and GIP. Most people are familiar with semaglutide (Ozempic, Wegovy), which activates GLP-1 alone. Tirzepatide does more by adding the GIP signal on top, and the results in clinical trials have been consistently stronger — up to 22.5% body weight reduction over 72 weeks. It's the compound that raised the bar before Retatrutide arrived.
How is Tirzepatide different from Semaglutide?
Semaglutide (Ozempic/Wegovy) activates one receptor — GLP-1. Tirzepatide activates two: GLP-1 and GIP. The GIP signal adds another layer of appetite and metabolic control that semaglutide doesn't have. In head-to-head research, Tirzepatide has consistently outperformed semaglutide on weight loss outcomes — which is why it's become the benchmark in this category. If you're comparing them: Tirzepatide is the stronger dual option; Retatrutide goes one step further with a third receptor.
How does Tirzepatide work?
Tirzepatide sends two signals your body responds to naturally — it's just sending them together, and at greater intensity. The GLP-1 signal slows digestion so you feel full longer, reduces appetite through the brain, and improves how your body responds to insulin after eating. The GIP signal adds improved fat metabolism and insulin sensitivity on top. The combined effect is less hunger, better blood sugar control, and more body fat being used as fuel — all at once.
What results has Tirzepatide shown in research?
Phase 3 SURMOUNT trial data showed mean body weight reductions of up to 22.5% over 72 weeks — one of the largest figures ever recorded in clinical weight management research. Participants also saw meaningful improvements in fasting blood glucose, HbA1c, waist circumference, and cardiometabolic markers. That data is what established Tirzepatide as the dual-agonist benchmark, and the standard newer compounds like Retatrutide are now being compared against.
How does Tirzepatide compare to Retatrutide?
Tirzepatide activates two receptors: GLP-1 and GIP. Retatrutide activates three: GLP-1, GIP, and glucagon. That third glucagon signal is what sets Retatrutide apart — it directly increases how much energy your body burns, which Tirzepatide doesn't do. Early Retatrutide trials have shown even greater fat loss results. Think of Tirzepatide as the proven dual-agonist option, and Retatrutide as where the research has gone next.
How do you reconstitute Tirzepatide?
Tirzepatide is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water (BAC water) immediately before use. Inject the BAC water slowly into the vial, directing the stream down the inside wall. Gently swirl to dissolve — do not shake. Once reconstituted, store at 2–8°C and use within 28 days. For a full step-by-step walkthrough, see our complete peptide reconstitution guide.
How should Tirzepatide be stored?
Store lyophilized Tirzepatide vials at -20°C, away from light and moisture. After reconstitution with BAC water, refrigerate at 2–8°C and use within 28 days. Do not freeze the reconstituted solution.
