Tirzepatide 40mg Injection Pen Kit
£180.00
Synedica Tirzepatide® Injection Pen Kit is the world’s most advanced weight loss solution. Commonly known as “Mounjaro,” tirzepatide is an advanced medication which suppresses appetite leading to significant weight loss. It does this by mimicking the effects of the GLP-1 and GIP receptors, which are natural hormones that makes humans feel full from eating much smaller portions of food.
The Synedica Tirzepatide® 40mg Injection Pen Kit contains 1 pen, 12 disposable needles and an instruction booklet.
Each pen has 40mg which can be delivered across 4 full doses of 10mg, or in increments of 2.5mg, 5mg, 7.5mg or 10mg.
Recommended dosage is 2.5mg for the first 4 weeks, then 5mg for the next 4 weeks. After 8 weeks the weekly dosage may be increased to 7.5mg or 10mg if necessary.
Always consult your doctor, nurse or pharmacist before using any new medication.
Synedica Tirzepatide® 40mg Injection Pen Kit is available at selected pharmacies across Germany, and potentially free for German citizens who qualify under Gesetzliche Krankenversicherung.

The Dual Agonist Mechanism
Tirzepatide acts at two incretin receptors at once, GLP-1 and GIP. Semaglutide targets GLP-1 alone, and adding GIP activity is what produced the step change in reported outcomes between the two generations. It is the reason tirzepatide displaced semaglutide as the reference compound in this class.
What tirzepatide does not do is act at the glucagon receptor, which is the addition unique to retatrutide. Glucagon receptor activity raises energy expenditure rather than only reducing intake, so the three compounds represent three successive additions to the same basic idea. Our comparison guide works through what the trial data shows for each.
Why Tirzepatide Has a Licensed Counterpart and Retatrutide Does Not
This is the most important practical difference between tirzepatide 40mg as a research material and the retatrutide we also supply. Tirzepatide has completed its regulatory path and is licensed in the United Kingdom under the brand name Mounjaro, prescribed through the NHS and private services. Retatrutide has not, and remains in Phase 3.
That distinction cuts both ways. Tirzepatide has a far better characterised clinical profile, with published safety data from completed trials and post marketing surveillance behind it, which makes it the more mature research reference. It also means anyone seeking treatment has a lawful licensed route available through a prescriber, and does not need research material at all. Research use supply and clinical supply are separate things, and this product is firmly the former.
Tirzepatide 40mg Cost Per Milligram
At £180 for 40mg, tirzepatide 40mg costs £4.50 per milligram. That is the lowest per milligram figure in our catalogue, below the £5.50 of the retatrutide 40mg kit and well below any smaller pen format on the UK market.
The same price floor logic applies here as anywhere in this category. Synthesis, purification, sterile fill and refrigerated logistics impose a hard minimum cost, so a 40mg tirzepatide kit advertised well under £100 is not a bargain on genuine material. Dividing price by milligrams before comparing anything is the fastest screen available, and our price index sets out the arithmetic across the whole range.
How Far a 40mg Kit Goes
Published tirzepatide trials escalated through 5mg, 10mg and 15mg weekly target amounts, reached in steps rather than started at target. Against those figures a 40mg kit spans a useful period.
| Weekly amount | Weeks covered by 40mg |
|---|---|
| 2.5mg | 16 |
| 5mg | 8 |
| 10mg | 4 |
| 15mg | 2.7 |
As with every compound in this class, the escalation is part of the protocol rather than an optional preamble. The tolerability profile reported in the trials belongs to the stepped schedule, not to the endpoint amount reached by any other route.
Pen Handling and Dial Accuracy
Confirm the tirzepatide 40mg dial increment before ordering, since a coarse device cannot be made fine afterwards, and prime the pen exactly as its instructions specify on first use. An unprimed pen delivers less than the dial shows, and on a 40mg kit that error carries through every subsequent measurement.
- Prime before the first delivery and record the volume discarded.
- Use a fresh needle for every draw to avoid contaminating a cartridge intended to last months.
- Record amounts as delivered rather than as dialled.
- Confirm the increment matches the amounts your protocol actually requires.
Storage and Cold Chain
- Refrigerate between 2 and 8 degrees and never freeze, since freezing denatures the peptide as reliably as heat does.
- Keep the kit in its original carton away from direct light.
- Store away from the refrigerator door, where temperature cycling is worst.
- Avoid repeated excursions, which accumulate across a multi month kit in a way they do not on a small pen.
- Log storage position and every deviation on the day it happens.
Batch Documentation
Every tirzepatide 40mg kit carries a printed batch number on the device itself, cross referenced to a certificate of analysis naming the issuing laboratory and test date rather than a generic template. Fill volume and concentration are both stated so the 40mg total can be confirmed arithmetically rather than taken on trust, because purity figures describe what proportion of the material is the intended compound and say nothing about how much material is present.

Tirzepatide 40mg Against Semaglutide and Retatrutide
| Compound | Receptors | Our format | Price | Cost per mg | Licensed counterpart |
|---|---|---|---|---|---|
| Semaglutide | GLP-1 | 8mg kit | £160 | £20.00 | Yes, Wegovy and Ozempic |
| Tirzepatide | GLP-1 and GIP | 40mg kit | £180 | £4.50 | Yes, Mounjaro |
| Retatrutide | GLP-1, GIP and glucagon | 40mg kit | £220 | £5.50 | No, still in Phase 3 |
Read the cost per milligram column carefully. Semaglutide looks expensive per milligram because it is used at far smaller amounts, so the comparison only makes sense alongside the schedules rather than on its own. Tirzepatide 40mg is genuinely the cheapest material we supply on a per milligram basis.
Ordering and Arrival Checks
Kits ship from the United Kingdom in insulated packaging with a coolant pack. Refrigerate on arrival, check the batch number against the paperwork, and record the packaging condition. Contact us before opening the device if anything looks wrong. Supplier checks worth running before any peptide order are in our buyer guide, and the full catalogue is on the shop page.
What the Tirzepatide Trial Programme Established
Tirzepatide 40mg is the best evidenced compound we supply, and that is the main reason to choose it as a research reference over anything newer. The SURPASS programme covered type 2 diabetes and the SURMOUNT programme covered obesity, both randomised, both completed, both published, with results reported across the 5mg, 10mg and 15mg weekly target amounts.
The pattern that matters for anyone designing work around this compound is the amount response relationship. Reported effect increased with the target amount across the studied range, and so did the gastrointestinal event burden, which clustered around escalation steps rather than running at a constant rate. Nausea, vomiting, diarrhoea and constipation dominated the reported events and were predominantly mild to moderate.
Because the programme completed and the product reached market, there is also post marketing surveillance behind tirzepatide that no research only compound has. Trial registrations and results are indexed on ClinicalTrials.gov, and the underlying literature on PubMed.
Why Laboratories Buy Research Grade Tirzepatide
A reasonable question is why anyone would source research grade tirzepatide 40mg for a compound that is licensed and prescribable. The answer is that the two supply routes exist for different purposes and are not substitutes.
- Licensed product is dispensed in fixed presentations aimed at clinical use, not at the quantities or concentrations a laboratory protocol may require.
- Comparative work across compounds needs the compounds on equivalent terms, which means research grade for all of them rather than one clinical product against several research materials.
- Analytical and stability work needs bulk material, not individually dispensed clinical units.
- A prescription supply cannot lawfully be redirected to laboratory use in any case.
None of that changes the boundary. Research grade tirzepatide 40mg is for laboratory work, and anyone whose actual need is treatment should be going to a prescriber for the licensed product rather than buying research material.
Counterfeit Risk Is Higher on This Compound Than Any Other
Because tirzepatide 40mg carries a well known licensed brand behind it, it attracts more counterfeiting than compounds with no household name. The imitation is aimed at consumers looking for a cheaper route to a prescribed product, and the packaging is copied convincingly enough that visual inspection settles nothing.
The failure modes are consistent and none of them are visible through a box window. An underfilled pen, a pen containing a cheaper peptide, and a pen containing nothing but sterile solution all look identical. This is why we publish fill volume and concentration, print the batch number on the device rather than only on the carton, and issue a certificate of analysis tied to that specific lot.
- Divide the asking price by 40 and compare against the £4.50 per milligram this kit represents. A figure far below the market floor is arithmetic telling you something.
- Ask for the batch number and its certificate of analysis before paying rather than after.
- Treat any seller offering the licensed brand without a prescription as operating outside the rules, and therefore not sourcing carefully either.
- Check the strength is printed on the device itself, because cartons get separated from pens.
- Ask what happens if the parcel arrives warm. A supplier without an answer has not thought about cold chain at all.
The same checks applied to any compound in this class are set out in our buyer guide, and the brand name question specifically is covered in the VLS pen guide.
Legal Position and Research Use Only
This tirzepatide 40mg kit is supplied for laboratory research use only and is not for human or veterinary consumption. Although tirzepatide has a licensed counterpart in the UK, research grade material is not a licensed medicine, has not been dispensed through a regulated pharmacy chain, and cannot lawfully be supplied for human use. It cannot be advertised with therapeutic claims under Advertising Standards Authority rules.
Anyone seeking treatment should speak to a registered UK prescriber about the licensed option, which is available and appropriate for that purpose. Regulatory information is published by the MHRA. Nothing on this page is medical advice.
