The evidence, explained

About Tirzepatide

Tirzepatide is a 39-amino-acid dual agonist of the GIP and GLP-1 receptors, built on the native GIP sequence rather than on GLP-1. The same molecule is licensed as a prescription medicine by Eli Lilly and sold as Mounjaro, and in the United States also as Zepbound. Those are regulated medicines; the vial on this page is neither one of them nor a medicine of any kind, it is research-grade material supplied for laboratory work. It is among the most studied metabolic peptides of the decade, with an extensive published clinical programme (SURPASS, SURMOUNT).

Research areas

Dual-incretin receptor pharmacology; glycaemic-control and body-weight models; and head-to-head comparative studies against selective GLP-1 agonists. How much of the observed effect the GIP arm accounts for is still argued over in the literature, which is most of why the comparative work keeps being done. Supplied for laboratory research into these pathways.

Supplied as lyophilized powder in a sealed glass vial. Store lyophilized vials at -20°C away from light and moisture; short-term storage at 4°C is acceptable. UK orders placed before 2pm on business days are dispatched the same day in discreet, protective packaging with tracked delivery.

Questions about Tirzepatide

What purity is Tirzepatide?

Tirzepatide is synthesised to a ≥96% purity specification and supplied as lyophilized powder in a sealed glass vial. The specification is the standard the compound is made to, and it is listed with the rest of its specifications on this page.

Is there a certificate of analysis for Tirzepatide?

Yes. A vial of Tirzepatide 30 mg was tested by an independent laboratory on 6 October 2026, and its certificate is shown on this page under the price of that size. The certificates for each size's most recent batches are also listed on our Quality page.

How should Tirzepatide be stored?

Store at -20°C. Keep away from light. Lyophilized vials keep best at -20°C, protected from light and moisture; short-term storage at 4°C is acceptable, and the powder is stable at room temperature for the time it spends in the post.

What comes with Tirzepatide?

Each unit is one sealed glass vial of lyophilized powder. Nothing to reconstitute it with is included: bacteriostatic water and the rest of the bench consumables are sold separately under Lab Essentials.

How fast is UK delivery?

Orders placed and paid before 2pm on a business day (Monday to Friday, excluding UK public holidays) are dispatched the same day via Royal Mail Tracked 24 in discreet, protective packaging, and arrive usually the next working day after dispatch. Standard shipping is £4.99, free on orders over £80, and orders over £120 arrive with a free research vial. The minimum order is £15, before delivery. We ship within the United Kingdom only.

Can I change my mind and return an order?

If you are buying as a consumer, yes: you have 14 days from delivery to cancel, without giving a reason, under the Consumer Contracts Regulations 2013. Tell us within 14 days, send the sealed vials back within 14 days, and we refund the goods plus the original delivery charge within 14 days. Return postage is at your cost unless the item was faulty or wrong. Opened vials are the one exception: our vials are sealed sterile, and regulation 28(3)(b) puts sealed goods that cannot be resold once unsealed, for health and hygiene reasons, outside the cancellation right.

Is Tirzepatide for human use?

No. Tirzepatide is supplied strictly for in-vitro laboratory research by qualified professionals. It is not a drug, food, cosmetic or supplement, it is not intended for human or veterinary use, and we do not provide dosage or administration guidance of any kind.
