Tirzepatide

Description

What is Tirzepatide?

Tirzepatide is a 39-amino-acid synthetic peptide engineered as a dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor. Developed by Eli Lilly under the code LY3298176, it was approved by the FDA in 2022 (marketed as Mounjaro) and has become one of the most extensively studied incretin-based compounds in current metabolic research.

It is supplied by Revial Labs as a lyophilised (freeze-dried) powder for reconstitution in bacteriostatic water. All product is intended strictly for laboratory research use.

Areas of Research Investigation

Tirzepatide’s dual-agonist mechanism has made it a focus of several active research areas, including:

• Incretin receptor pharmacology — studies examining simultaneous GIP and GLP-1 receptor activation and downstream signalling.
• Metabolic and glycaemic regulation models — investigation of insulin secretion, glucose homeostasis, and pancreatic beta-cell activity in preclinical models.
• Adipose tissue and energy balance research — studies of GIP receptor activity in adipose tissue and its role in energy utilisation.
• Comparative incretin research — head-to-head studies against selective GLP-1 receptor agonists such as dulaglutide and semaglutide.

This is a summary of published research directions and should not be interpreted as claims about the compound’s effects in humans. Tirzepatide is a prescription medication in the UK; the product supplied by Revial Labs is intended solely for in vitro laboratory research and is not for human or veterinary use.

Reconstitution

Tirzepatide is typically reconstituted in bacteriostatic water for research purposes. Bacteriostatic water contains 0.9% benzyl alcohol, allowing storage of the reconstituted solution over several weeks under refrigeration.

For step-by-step guidance, see our article How to Reconstitute Research Peptides, or use our Peptide Reconstitution Calculator to determine the correct solvent volume for your intended concentration.

Storage and Handling

• Before reconstitution: Store at 2–8°C (refrigerator) for long-term storage. Short-term room-temperature storage is acceptable during shipping.
• After reconstitution: Store the solution at 2–8°C and use within four weeks.
• Avoid: Direct sunlight, freeze-thaw cycles, and repeated agitation.

Frequently Asked Questions

What is included with this product?

One sealed vial of lyophilised Tirzepatide powder in the quantity selected. Bacteriostatic water, syringes, and alcohol swabs are sold separately — see our Starter Accessory Pack for a bundled option.

How pure is Revial Labs Tirzepatide?

All Tirzepatide supplied by Revial Labs is manufactured to ≥99% purity and independently verified by High-Performance Liquid Chromatography (HPLC). A batch-specific Certificate of Analysis is available on request.

What is the difference between Tirzepatide and Retatrutide?

Both are incretin-based peptides but differ in receptor targets. Tirzepatide is a dual agonist at GIP and GLP-1 receptors, while Retatrutide is a triple agonist that additionally activates the glucagon receptor. See our Retatrutide research overview for more.

How is Tirzepatide shipped?

Orders are dispatched via Royal Mail tracked delivery from the UK, typically within one working day. Peptides remain stable at ambient temperature during transit; refrigeration is recommended once received.

Is a Certificate of Analysis included?

A batch-specific COA verifying identity, purity, and mass spectrometry is available on request. Contact us with your order number and we will send the corresponding document.
