About Tirzepatide
What is Tirzepatide?
Overview
What is Tirzepatide?
Tirzepatide is a synthetic 39-residue peptide that acts as a dual agonist at the GIP and GLP-1 receptors. The backbone carries a C20 diacid fatty-acid conjugate that extends its plasma half-life through albumin binding. It is supplied as a lyophilised powder in sealed vials, boxed in tens, for laboratory research use only. Each tirzepatide vial holds a single strength, from 5 mg to 120 mg, and UK and US orders ship the same vials. Because it is a peptide rather than a small molecule, the tirzepatide peptide sold for research is the same compound whether it is written that way or simply as tirzepatide.

These are catalogue target specifications, not batch results. The 99%+ purity figure is the specification we buy to. The authoritative figures for any particular box are the ones printed on that box’s Certificate of Analysis, which is lot-specific. What research grade actually means explains the difference. Terms such as HPLC purity and net peptide content are explained in the peptide glossary.
We make no “third-party verified” claim for a batch unless the matching report is supplied with it. Ask for the current COA for the lot in stock before you order — we will send it.

Storage & reconstitution
Handling
How should Tirzepatide be stored and reconstituted?
Sealed vials tolerate ambient temperature in transit and keep at −20 °C beyond that. Reconstitute slowly down the vial wall, swirl rather than shake, then refrigerate at 2–8 °C and aliquot before freezing.
Why each of those matters, and what a freeze–thaw cycle actually costs: peptide handling and storage reference. How long a mixed vial keeps: reconstituted peptide shelf life.
What it is researched for
Research Context
What is Tirzepatide researched for?
Below is a plain-English summary of what published research has investigated, and what it has found. These are descriptions of research activity and published results. They are not claims about what Tirzepatide does, and nothing here is a statement that it is safe or effective for any purpose.
Dual receptor activation
Tirzepatide activates both the GIP and GLP-1 receptors from one molecule. It is not a balanced agonist: it is considerably more potent at GIP, and how that imbalance contributes to the overall effect is still an open research question. 1
The role of GIP
GIP is the interesting part. On its own it does little for body weight, yet combined with GLP-1 activation the effect appears larger than GLP-1 alone. Working out why is an active area of incretin research.

Batch COA
Verification
Does Tirzepatide come with a COA?
Yes — every box. Each batch of Tirzepatide is analysed by an independent third-party laboratory, and the certificate is tied to the batch number on the vial label.

Questions & answers
Questions
Tirzepatide questions, answered
Is tirzepatide a peptide?
Yes. Tirzepatide is a synthetic 39-residue peptide — a chain of amino acids joined by peptide bonds — rather than a small molecule. It carries a C20 diacid fatty-acid conjugate on that backbone, which is a modification to a peptide, not a departure from being one. The molecular weight and sequence stated above are what a mass spectrometry trace confirms, where the COA includes one.
Is research tirzepatide the same as the licensed medicine?
The molecule is the same peptide. What differs is everything around it: a licensed medicine is manufactured, formulated, tested and released under a marketing authorisation for human use. Research-grade material carries none of that and is not a substitute for it.
How does tirzepatide differ from retatrutide?
Both are long-acting incretin agonists built on a similar acylated peptide scaffold. Tirzepatide is a dual agonist, binding the GIP and GLP-1 receptors. Retatrutide is a triple agonist, adding activity at the glucagon receptor. In receptor-selectivity work the two are frequently run side by side for exactly that reason.
How much does Tirzepatide cost?
Tirzepatide starts at $4.50 per vial, sold in boxes of 10 vials at $45.00 per box (about £33.71). 11 strengths available: 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, 80 mg, 100 mg, 120 mg. There is no minimum order.
Can I buy Tirzepatide 10mg vials in the UK?
Yes. Tirzepatide 10mg comes in boxes of 10 vials at $75.00 per box ($7.50 per vial, about £56.19 per box), sent tracked to UK addresses. There is no minimum order.
Do you ship Tirzepatide to the US?
Yes, to all 50 states. Tirzepatide ships FedEx tracked from our UK stock or direct from our verified manufacturer, arriving 5 to 8 working days after dispatch, and is billed in US dollars from $4.50 per vial. We hold no US stock. If US customs seize an order, we reship it once at no cost. Our tirzepatide US guide covers FDA status and US shipping in full.
How is Tirzepatide shipped to the UK and USA?
Tracked to the UK, USA, EU and worldwide, in plain packaging, dispatched within 1–2 working days. Country-by-country estimates are on the shipping page.
