Research peptides in Lithuania: delivery, prices in euros, lab reports

A search for peptides in Lithuania mixes two different worlds. One is cosmetics: serums and creams with a fraction of a percent of peptide, sold per millilitre.

The other is laboratory reagents: pure peptide in a sealed glass vial, measured in milligrams and checked by a lab. The two cannot be compared, neither by content nor by price.

Most Lithuanians search in Lithuanian: « peptidai » or « peptidai pirkti ».

This page is in English because many of the labs that order from Lithuania work in English: university groups in Vilnius and Kaunas, biotech teams in Vilnius, and visiting researchers.

The Lithuanian version of this guide, with the same catalogue, is Peptidai pirkti Lietuvoje: kainos eurais, Janoshik ataskaitos ir pristatymas iš ES.

A research peptide is a laboratory reagent: a lyophilised solid in a sealed glass vial, identified by its amino-acid sequence and its mass, and checked by HPLC and mass spectrometry.

It is sold labelled for research, priced per vial, and compared per milligram. That is the frame for everything below. The product pages, the basket and the checkout of OXpeptides are in English, with prices in euros.

OXpeptides ships to Lithuania from a warehouse inside the European Union.

Lithuania sits inside the EU customs union, so a parcel posted from another member state crosses no customs border: Lithuanian Customs (Muitinė) never sees it and no import VAT is due. The price on the page is the price paid.

A parcel from outside the EU is an import, whatever its value.

The EU removed the old small-parcel exemption, so even a cheap vial from outside the Union owes Lithuanian import VAT at 21 % on the goods plus shipping.

Customs duty can apply on top, and the carrier charges its own fee for clearing the parcel before delivery:

The OXpeptides terms for Lithuania, from Vilnius to Klaipėda:

Lithuania uses the euro, so the price on the page is the price on the bank statement, with no conversion.

One e-mail confirms the order at once, a second carries the tracking link when the parcel leaves. The full country list is on the shipping page.

Peptide prices in Lithuania can only be compared fairly per milligram.

Sellers usually quote a price per vial, and that number hides the real cost, because a 5 mg vial and a 10 mg vial are not the same purchase. Divide the price by the milligrams on the label, then compare vials of the same size.

Inside one catalogue, the size moves the price per mg more than the shop does. OXpeptides retatrutide costs €8.99/mg in the 10 mg vial, €7.50/mg in the 20 mg vial and €6.50/mg in the 30 mg vial.

A long research series is cheaper in large vials; a short one wastes less in small ones, since the powder stays stable until the vial is opened.

In the basket, the price per vial also drops on its own from 3 and from 5 vials of the same size.

One more correction to any per-mg figure: it assumes the vial holds what the label says.

A « 10 mg » vial that holds 7 mg is the most expensive vial in Lithuania per real milligram, whatever the sticker.

Compare only shops that publish a lab report for the size they sell; the comparison of research peptide suppliers in Europe does exactly that.

In Lithuania, medicinal products are overseen by the State Medicines Control Agency, the VVKT (Valstybinė vaistų kontrolės tarnyba).

The VVKT handles authorisations, inspections and market surveillance. A product offered for people, with an amount to take or a promised outcome, is a medicinal product in its eyes and needs an authorisation before it can be sold.

Research peptides have no such authorisation.

That is why they can only be offered as laboratory reagents: labelled « for research use only », described by their chemistry, with no instructions for people or animals.

The line is drawn by how a product is presented, not by its name. A shop that posts amounts, testimonials or promised outcomes next to a vial is presenting it as a medicinal product, whatever the label says.

The World Anti-Doping Agency list names BPC-157 (class S0) and TB-500 (class S2) as prohibited, which matters for any lab that works with sport organisations.

This page is not legal advice; each institution's own rules apply to its lab.

Retatrutide (LY3437943) is an investigational peptide developed by Eli Lilly. In laboratory models it binds three receptors of the incretin and glucagon family.

Eli Lilly runs phase 3 studies on it, and it has no marketing authorisation from the European Medicines Agency, so the VVKT register lists no retatrutide product.

What circulates in Lithuania is lyophilised powder sold as a research reagent.

For that powder, the useful document is a lab report tied to the size in the basket. The OXpeptides reports come from Janoshik Analytical in Prague, one per size:

The vials are on the retatrutide 10, 20 and 30 mg page, the full guide with sizes and storage is buy retatrutide in Europe, and every report sits in the lab report library.

After retatrutide, these are the OXpeptides vials Lithuanian labs add to the same order.

BPC-157 10 mg costs €54.90 (€5.49/mg); TB-500 10 mg is the fragment of thymosin beta-4 that labs often study alongside it, and KLOW 80 mg combines GHK-Cu, BPC-157, TB-500 and KPV in one vial.

MOTS-c is a 16-amino-acid mitochondrial peptide, and Semax and Selank are short heptapeptides first described by Russian research institutes.

All of them ship in the same parcel, with the same delivery time to Lithuania, so a mixed order costs one shipping fee or none above €120.

GHK-Cu sold in Lithuanian beauty shops is a cosmetic ingredient: creams and serums with a fraction of a percent of copper peptide in a finished formula, listed as Copper Tripeptide-1.

A research vial holds the peptide itself, glycyl-L-histidyl-L-lysine bound to a copper ion, as a blue lyophilised powder measured in milligrams.

The two are priced differently: a serum per millilitre of product, a vial per milligram of peptide.

The OXpeptides GHK-Cu 100 mg costs €59.90 (€0.60/mg), with Janoshik report 217016 for the lot on sale (99.603 % purity). Its sister peptide is on the AHK-Cu page, and GHK-Cu vs AHK-Cu compares them.

Bacteriostatic water is sterile water with 0.9 % benzyl alcohol as a preservative, supplied in a sealed glass vial as a laboratory diluent.

Check the words « bacteriostatic » and « 0.9 % benzyl alcohol », a sealed cap, a lot number and an expiry date. The OXpeptides bacteriostatic water ships in the same parcel as the peptides.

On arrival the seal should be intact and the powder dry, as a cake or a fine powder.

Sealed vials keep best in a freezer at −20 °C, in their box, away from light and moisture. The guide lyophilized peptides storage covers shelf life.

A peptide seller serving Lithuania can be checked in six steps, none of which needs an order:

1. Company details. Online shops serving Lithuania must show a company name, an address and a registration number. A social media profile or a messenger handle is not one.
2. A lab report per size. One PDF for the smallest vial, reused for the larger ones, says nothing about the vial in the basket.
3. A verifiable report. Janoshik reports carry a task number and a key; typed on janoshik.com, they must open the same document as the shop's.
4. A measured quantity, not only a purity. « 99 % pure » on 7 mg of a « 10 mg » vial is still 7 mg.
5. Dispatch from the EU. Prices in dollars or yuan usually mean customs and 21 % VAT at the door.
6. Card payment and a written return policy. Bank transfers to a private account and crypto-only checkouts are warning signs.

The long version is how to check a peptide supplier, and every line of a report is explained in Janoshik test report.
