RESEARCH OVERVIEW
What is Tirzepatide?
Tirzepatide is a linear 39-amino-acid peptide based on the native GIP sequence and modified with a C20 fatty diacid moiety, which enables albumin binding and a prolonged half-life. It is an agonist at both the GIP and GLP-1 receptors, with greater affinity for the GIP receptor.
It is one of the most extensively studied incretin-based peptides, with a large published literature covering glycaemic, body weight and lipid endpoints. Researchers commonly use it as the reference dual agonist when comparing single, dual and triple receptor pharmacology.

- Reference comparator for semaglutide and retatrutide studies
Tirzepatide vs Semaglutide
Semaglutide is a selective GLP-1 receptor agonist. Tirzepatide adds GIP receptor agonism, so the pair is often used to separate GLP-1 effects from combined incretin effects.

Laboratory handling
Reconstitution
- Allow the sealed vial to reach room temperature.
- Wipe the stopper with an alcohol swab.
- Add diluent slowly down the inside wall of the vial.
- Swirl gently until dissolved. Do not shake.
- Label with concentration and date, then refrigerate.
Storage
- Lyophilised: -20°C for long-term storage, sealed and dry, away from light.
- Short term: 2 to 8°C for weeks in the sealed vial.
- Reconstituted: 2 to 8°C, protected from light. Avoid repeated freeze-thaw cycles.
Tirzepatide FAQs
Is Tirzepatide for human use?+
No. Tirzepatide is sold strictly for laboratory research use only. It is not a medicine, food supplement or cosmetic and must not be used in humans or animals.
How is Tirzepatide tested?+
Each batch is tested for identity and purity by an independent laboratory using HPLC and mass spectrometry. Certificates are published on our Lab Reports page as each batch is released, and you can request the report for your batch at any time.
How should Tirzepatide be stored?+
Lyophilised material should be stored sealed, dry and protected from light, ideally at -20°C for long-term storage. After reconstitution, laboratories typically store solutions at 2 to 8°C and avoid repeated freeze-thaw cycles.
How quickly will my Tirzepatide order arrive?+
Orders placed before 2pm on a working day are dispatched the same day by Royal Mail Tracked 24. Delivery is free over £50, otherwise £4.99.
Which Tirzepatide strengths are available?+
Tirzepatide is available in 10mg (£54.99), 20mg (£64.99), 40mg (£99.99), 60mg (£139.99). Larger vials cost less per mg.
Do I need bacteriostatic water for Tirzepatide?+
Lyophilised peptides are supplied as dry powder. Laboratories reconstitute them with a suitable diluent such as bacteriostatic water, which we stock separately. Our reconstitution calculator works out the resulting concentration.
