This page is for anyone looking to buy tirzepatide as a reference material, and it sets out the tirzepatide price across every pack size we list. You will find the price table with the cost per milligram worked out, a description of the molecule, the neighbouring compounds in our catalogue, handling notes and our shipping terms for the United Kingdom and Ireland.
Tirzepatide is a research chemical here. It is not a medicine, not a supplement and not a cosmetic, and we say nothing about what anyone would observe while working with it. What we describe is chemistry, packaging and logistics.
Price and packaging
All prices on the site are in euros. The third column is the price divided by the milligrams in the pack, so the sizes can be read on the same basis.
| Product and pack | Price | Price per mg |
|---|---|---|
| Tirzepatide vial 10 mg | € 64,95 | € 6,50 |
| Tirzepatide vial 20 mg | € 94,95 | € 4,75 |
| Tirzepatide vial 30 mg | € 139,95 | € 4,67 |
| Tirzepatide vial 40 mg | € 179,95 | € 4,50 |
| Tirzepatide vial 60 mg | € 229,95 | € 3,83 |
| Tirzepatide bundle, 3 x 30 mg (90 mg) | € 399,95 | € 4,44 |
| Tirze GLP-2 pen 10 mg | € 99,95 | € 10,00 |
| Tirze GLP-2 pen 20 mg | € 134,95 | € 6,75 |
| Tirze GLP-2 pen 30 mg | € 179,95 | € 6,00 |
| Tirze GLP-2 pen 60 mg | € 269,95 | € 4,50 |
| Tirzepatide oral 500 mcg | € 79,95 | Not comparable |
The arithmetic is worth reading, because the biggest box is not automatically the cheapest. The 60 mg vial works out at € 3,83 per milligram, the lowest figure in the table. The bundle holds 90 mg for € 399,95, so € 4,44 per milligram, dearer per milligram than that single vial. The pen is a separate format with its own hardware and sits higher again. The 500 mcg oral tablet is not sensibly compared per milligram with a vial.
What tirzepatide is
Tirzepatide is a synthetic single-chain peptide of 39 amino acids, registered under CAS number 2023788-19-2, with a molecular mass of roughly 4,813 g/mol. Its backbone is modelled on glucose-dependent insulinotropic polypeptide rather than on glucagon-like peptide 1, and that is the structural point which sets it apart from the other compounds in this corner of the catalogue.
Positions 2 and 13 carry alpha-aminoisobutyric acid, a non-proteinogenic residue used in this class to slow enzymatic cleavage of the chain. The lysine at position 20 carries a C20 fatty diacid on a short glutamate and ethylene glycol linker, which gives the construct a high affinity for serum albumin. That is a physicochemical property of the molecule and nothing more.
In the literature it is classified as a dual agonist at the GIP and GLP-1 receptors, where semaglutide is described as acting at the GLP-1 receptor alone. These are groupings of substances, not statements about what any of them do.
Where it sits in the catalogue
The closest neighbour is semaglutide, a 31 amino acid GLP-1 analogue with its own fatty acid side chain and a different parent sequence. One step along is retatrutide, from the same family and described as a triple receptor agonist. Cagrilintide sits in a separate group, being an amylin analogue rather than an incretin analogue, while orforglipron is not a peptide at all but a small molecule. The full range is on our buy peptides page.
Form, handling and storage
A vial holds a lyophilised cake. Bacteriostatic water goes down the inside wall of the vial rather than straight onto the cake, and the vial is then swirled gently, never shaken, until the powder has fully dissolved. The volume of water added sets the concentration, and our peptide calculator works out the concentration per unit of volume for you.
Unopened powder keeps at room temperature, away from light. Once reconstituted, the vial belongs in the fridge and not the freezer, since a freeze and thaw cycle is hard on a peptide in solution. The pen is kept between 2 and 8 degrees Celsius and must likewise not be frozen. Oral tablets are stored dry and dark. Batch specific storage notes are printed on the certificate.
Shipping and analysis
Everything ships from the Netherlands. To the United Kingdom the rate is a flat € 15,95, with shipping free from € 200. To Ireland it is a flat € 14,95, again free from € 200. Prices on the site are in euros.
The United Kingdom is not in the European Union, so a parcel from the Netherlands to a British address is an import. Any import VAT or duty due on it is charged by the carrier to the recipient, and that sits outside the price you pay us. Ireland is in the European Union, so no such import charge arises on an Irish delivery. Every batch is analysed and a certificate of analysis is available for the material you receive.
Frequently asked questions
What may I use this for?
Laboratory and research purposes only. It is not for human or veterinary use, and we give no dosing advice of any kind.
Which pack costs the least per milligram?
The 60 mg vial, at € 3,83 per milligram. The 90 mg bundle comes to € 4,44 per milligram, so a larger total quantity does not always mean a lower unit price.
How does tirzepatide differ from semaglutide?
Different length, different parent sequence, different receptor classification. Tirzepatide runs to 39 residues on a GIP backbone, semaglutide to 31 on a GLP-1 backbone.
Can I see the certificate of analysis?
Yes. A certificate is available for the batch you are sent, and batch certificates are published on our laboratory reports page.
Why is the price in euros for a British order?
We are based in the Netherlands and price the whole catalogue in euros. Your card issuer converts at its own rate, and any import VAT or duty is billed separately by the carrier.
For laboratory and research use only. Not for human or veterinary use.
