Buy tirzepatide

Buying tirzepatide comes in two forms here: a lyophilised vial of 10 mg and a pre-filled research pen of 30 mg. Both are HPLC verified at a minimum of 99 percent purity, sealed and batch traceable. The pen works out roughly twenty percent cheaper per milligram than the vial.

What a dual agonist is

Tirzepatide is a synthetic peptide of 39 amino acids and the first dual GLP-1/GIP receptor agonist in clinical use. It activates two incretin receptors at once.

• GLP-1 receptor: appetite suppression, delayed gastric emptying, glucose-dependent insulin release
• GIP receptor: insulin sensitisation, lipid handling in adipose tissue

At physiological concentrations the receptor balance leans slightly towards GIP. The C20 fatty diacid side chain enables albumin binding, giving a plasma half-life of roughly five days.

What published research reports

SURMOUNT-1 (Jastreboff et al., NEJM 2022) reports an average body weight reduction of 22,5 percent after 72 weeks at a weekly dose of 15 mg, the largest weight endpoint within the dual agonist class. In the head-to-head trial SURPASS-2, tirzepatide outperformed semaglutide on both glycaemic and weight endpoints, across all three dosing arms.

These are research findings from published literature. We give no protocol and no dosage.

How to judge a peptide supplier

The research peptide market is not regulated the way a pharmacy is. The difference between suppliers therefore lies entirely in what they can demonstrate, not in what they claim. Four points are enough.

A certificate per batch, not per product. A certificate attached to a product page rather than to your specific batch number tells you nothing about the vial in your hands. Ask for the batch number.

Two independent methods. HPLC shows purity, mass spectrometry confirms the compound is what the label says. HPLC alone is half the story. Karl Fischer titration measures water content on top of that, which is directly tied to how long the powder stays stable.

A cold chain that matches the distance. Lyophilised peptide tolerates room-temperature transport less well the longer it lasts. A shipment weeks in transit from another continent is a different product than the same powder that stayed within the EU.

A payment method that leaves a trail. Wero, credit card, Apple Pay and Google Pay all do. Suppliers who accept only crypto deliberately avoid that.

What is in the package

• The sealed vial or pen in your chosen format, batch traceable
• Protective cold packaging, cold chain within the EU
• Discreet outer packaging with no reference to the contents
• Certificate of analysis on request, tied to your batch number

We do not include bacteriostatic water or needles. That is deliberate: we sell the research compound, not the accessories.

Reconstitution and storage

The sealed vial is stored refrigerated at 2 to 8 degrees, protected from light, and reconstituted with sterile bacteriostatic water. The pen holds a premixed solution and is stored the same way.

Paying from anywhere in the EU

You complete your order first. You then reach a secure payment page showing the exact amount and your order number, where you choose how to pay: Wero, credit card, Apple Pay or Google Pay. Which methods appear depends on the country you are paying from. No card number is entered on our site.

Shipping and customs across Europe

We ship from within the EU with cold chain. For any EU destination that means no customs clearance, no import duty and no gap in temperature control. Sunday is the only day we do not ship. Above 200 euro shipping is free.

One thing worth stating plainly, because it comes up constantly in English searches: the United Kingdom is no longer in the EU. A shipment there goes through customs clearance with a delay we cannot control, and a customs depot is not a cold room. The same applies to Switzerland and Norway. We say this before you order rather than after.

Research use only

What we supply are research compounds for laboratory use. They are not a medicine, are not sold as one, and are not intended for human consumption. That distinction is the entire legal point: a research compound falls under different rules than an approved medicinal product.

For that reason we give no dosage, no protocol and no usage advice. What we do give is documentation.

Frequently asked questions

Which is cheaper per milligram, vial or pen?

The pen, at 7,67 euro per milligram against 10,00 for the 10 mg vial.

How does tirzepatide differ from semaglutide?

Semaglutide acts on one receptor, tirzepatide on two. In SURPASS-2 tirzepatide outperformed semaglutide on both endpoints.

How does it compare to retatrutide?

Retatrutide adds a third receptor, glucagon. Tirzepatide stops at two.

Do you ship to the UK?

The UK left the EU, so customs clearance applies with a delay we cannot control.

How can I pay?

With Wero, credit card, Apple Pay or Google Pay.

How do I reconstitute the vial?

With sterile bacteriostatic water. The volume you add determines the working concentration.

How do I store it?

Refrigerated at 2 to 8 degrees Celsius, protected from light.

Do I get a certificate of analysis?

Yes, on request and tied to your batch number.

What may I use this for?

Laboratory research only. Not for human consumption, not a medicinal product and not for diagnostic use.

For research purposes only. Not for human consumption. Not a medicinal product. Not for diagnostic use.
