How to check a batch

A test report is only worth as much as it can be verified. Every vial carries its batch number, every report the lab's verification key.

  1. 1Read the batch numberIt is printed on the label of every vial, e.g. “C208”.
  2. 2Open the reportThe full HPLC report is listed under the batch number – here or on every product page.
  3. 3Verify at the labEnter the verification key at janoshik.com/verify: the lab shows its own copy of the report.

Legal status

Research peptides are not approved medicines. We sell them exclusively as laboratory reagents for research – not for use in humans or animals. That is why we give no dosing or usage advice, test every batch independently and deliver with a proper invoice from the EU.

What are research peptides?
Short amino-acid chains produced as laboratory reagents for in-vitro research and preclinical models. They are not medicines, foods or cosmetics.
May I buy them?
That depends on the substance and the intended use, for example under medicines or anti-doping law. We only sell to buyers who confirm with every order that they are of age and buy exclusively for research and laboratory purposes. The buyer is responsible for the specific use.
What don't we sell?
No medicines and no ready-to-use preparations. We give no dosing or usage advice and do not supply for use in humans or animals.

FAQ

Frequently asked questions

All questions & answers →
How fast is delivery?

We ship within 24–48 hours of payment. Transit to Germany is 1–2 working days with DHL, 2–6 working days to the rest of the EU – always tracked.

Are there customs or import duties?

Not within the EU: we ship from Poland, the goods stay in the EU single market and your country's VAT is included in the price. Only for deliveries outside the EU, e.g. Switzerland or the United Kingdom, may the recipient pay import charges.

How can I pay?

By SEPA transfer, Revolut or Bitcoin (−10 % on the goods value). You receive our bank details by e-mail after ordering; the Bitcoin address is shown right in the checkout. The minimum order is €200.00.

How do I store the vials?

Lyophilized peptides are stable in transit. After receipt store them dry, protected from light and cold; the exact temperature – usually −20 °C – is on every product page.

Do I get an invoice?

Yes. You receive a receipt showing your delivery country's VAT by e-mail. Companies from another EU country with a valid VAT ID order without VAT (reverse charge).

Can I return sealed vials?

Yes, within 14 days of receipt as long as the seal is intact; returns are free. Opened vials are excluded from withdrawal because purity and specification can no longer be guaranteed. Statutory warranty rights remain unaffected.

Buying peptides in Europe: what matters

Anyone buying research peptides usually compares three things: is the vial really what the label says? Will the parcel arrive reliably? And is the seller accountable, with an imprint, an invoice and clear rules? Peptidkauf answers all three before you buy.

An independent lab tests the purity and content of every batch by HPLC. The report is public under the batch number printed on every vial and can be verified at the lab with its key. A claim like “99 % purity” becomes a document you can read yourself – including the content actually measured in milligrams.

We ship from Poland within the European Union, so orders from Germany, Austria, the Netherlands and the other EU countries involve no customs formalities; your country's VAT is included and shown on the receipt. Delivery to Germany takes one to two working days with DHL, free from €250.

The range covers more than a hundred products: incretin analogues such as Retatrutide, Tirzepatide and Semaglutide, regeneration peptides such as BPC-157 and TB-500, copper peptides such as GHK-Cu, GH secretagogues, neuropeptides, bioregulators and lab supplies such as bacteriostatic water. The price per milligram is on every card so pack sizes can be compared fairly.

All products are intended exclusively for research and laboratory use. We give no dosing or usage advice and do not sell for use in humans or animals. What this means legally is explained in our guide to the legal situation.
