Research peptides in Sweden: what ships from the EU, price per mg, lab reports

Type « peptides Sweden » into Google and the first page holds three things that rarely answer the same question.

First, Swedish web shops priced in kronor, with short product pages and, in most cases, no lab report for the size you buy.

Second, Nordic pages that use the word « peptide » to talk about authorised medicines such as Mounjaro, which no research supplier can sell.

Third, PolyPeptide in Malmö: a real peptide factory that manufactures active ingredients for pharmaceutical companies under contract. It does not sell vials to labs or to individuals.

The question most researchers in Stockholm, Gothenburg or Uppsala actually have is narrower: which supplier ships a sealed, tested vial to Sweden, at what price per milligram, and will the parcel stop at customs.

That is what this page answers, using our catalogue as the worked example and listing the checks that apply to any other shop.

Research peptides are laboratory reagents.

A vial of BPC-157, TB-500, GHK-Cu or retatrutide holds a lyophilised solid identified by its amino acid sequence and its molecular mass, checked by HPLC and mass spectrometry.

Labs, universities and independent researchers buy them online, labelled for research use only.

Most searches in Sweden are typed in Swedish: « köpa peptider », « peptider Sverige » or « köpa retatrutide ».

Those queries bring up the same kronor shops, plus forum threads asking which of them is genuine. This page is in English because a large share of Swedish research teams work in English.

If you prefer Swedish, our retatrutide guide for Sweden, with the same facts, is on köpa retatrutide i Sverige.

Sweden is in the EU customs union, so the origin of a parcel decides what you pay at the door. A vial sent from outside the EU is an import, whatever its value: the EU no longer exempts small parcels under €22.

Tullverket, the Swedish customs service, charges Swedish VAT at 25 % on the goods plus shipping, duty can apply on top, and the carrier adds a handling fee before it releases the parcel.

That covers vials posted from the United Kingdom since Brexit, from the United States, from China and from Switzerland.

Those parcels also sit in a depot while the declaration is processed, and a parcel of unauthorised medicines can be held.

A parcel posted inside the EU crosses no customs border. Ours leave a warehouse in the European Union in a plain sealed box with a tracking number, and are handed to the national post for the last mile:

A confirmation e-mail arrives at once and a second one with the tracking link when the parcel leaves. The full country list is on the shipping page.

Sweden kept the krona, and our prices are in euros. In practice that changes very little.

You pay by card with 3-D Secure, without creating an account, and your Swedish bank converts the euro amount into kronor at its rate on the day.

The amount on the order page is the amount charged: no Swedish VAT is added later at the door, because the parcel never passes customs.

To compare with a shop priced in kronor, convert our euro price at your bank's rate, then divide each price by the milligrams on the label.

A kronor price from a Swedish shop is not automatically cheaper once you count a report you cannot verify, or a vial that holds less than its label.

A vial price alone tells you little, because a 5 mg vial and a 10 mg vial cannot be compared.

Divide the price by the milligrams on the label and compare vials of the same size.

For retatrutide, our milligram 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; the larger the vial, the cheaper each milligram.

The per-mg figure also assumes the vial holds what its label says. A « 10 mg » vial that contains 7 mg is the most expensive vial on the market per real milligram.

That is why price comparisons only mean something between shops that publish a report giving the measured quantity for the size you buy. In our basket, the price per vial drops on its own from 3 and from 5 vials of the same size.

Sealed vials keep best in a freezer at −20 °C, in their box, away from light and moisture. On arrival the seal should be intact and the powder dry. Lyophilized peptides storage covers shelf life.

Retatrutide (LY3437943) is an investigational peptide developed by Eli Lilly. In laboratory models it acts on three receptors: GIP, GLP-1 and glucagon.

It is in phase 3 studies and has no marketing authorisation from the European Medicines Agency, so Läkemedelsverket has approved no retatrutide product and no Swedish pharmacy stocks it.

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

For that powder, the only useful document is a lab report tied to the size you buy. Ours come from Janoshik Analytical:

The vials are on the retatrutide 10, 20 and 30 mg page, and the full purchase guide is buy retatrutide in Europe. We publish nothing about use in people; a shop that does is selling an unauthorised medicinal product.

• GHK-Cu. Swedish beauty shops sell copper peptide serums with a fraction of a percent of peptide in a cosmetic base, priced per millilitre. A research vial holds the peptide itself, glycyl-L-histidyl-L-lysine bound to Cu²⁺, as a blue powder priced per milligram. Our GHK-Cu 100 mg costs €59.90 (€0.60/mg), with Janoshik report 217016 for the lot on sale (99.603 % purity). GHK-Cu vs AHK-Cu sets it next to AHK-Cu.
• BPC-157 and TB-500. Two research peptides often studied together in tissue models. BPC-157 10 mg costs €54.90; see buy BPC-157.
• KLOW. GHK-Cu, BPC-157, TB-500 and KPV in one 80 mg vial, explained on KLOW peptide.
• MOTS-c, Semax and Selank. A mitochondrial-derived peptide and two short peptides studied in neuroscience models.
• Bacteriostatic water. Water with 0.9 % benzyl alcohol in a sealed vial, 3 mL at €10.90, sent in the same parcel at no extra shipping cost. Check any vial for « 0.9 % benzyl alcohol », a lot number and an expiry date; see where to buy bacteriostatic water.

Five checks, none of which needs an order:

1. A lab report per size. One PDF for the smallest vial, reused for the larger ones, says nothing about the vial you buy.
2. A verifiable report. A Janoshik report carries a task number and a key; typed on janoshik.com, they must open the same document the shop shows.
3. A measured quantity, not only a purity. « 99 % pure » on 7 mg of a « 10 mg » vial is still 7 mg.
4. Dispatch from the EU. A shop priced in kronor can still post from outside the EU; read where the parcel leaves from, not the currency.
5. A clear return policy and card payment. Crypto-only checkout, Swish to a private number or a bank transfer to a private account are warning signs.

Instructions for people, testimonials or promised outcomes on a product page mean the shop is selling a medicinal product without authorisation.

The long version is how to check a peptide supplier; every heading of a report is explained in Janoshik test report.

In Sweden, Läkemedelsverket, the Swedish Medical Products Agency, decides what counts as a medicinal product and authorises its sale, within the EU framework shared with the European Medicines Agency.

A product presented for use in people, with an amount to take or a promised outcome, is treated as a medicinal product and needs an authorisation.

Research peptides have none, which 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.

Tullverket can hold parcels of unauthorised medicines ordered online, most of them from outside the EU.

A reagent sold and labelled as such by an EU seller is a different case, but the line is drawn by how the product is presented, not by its name.

Athletes under anti-doping rules should know that the World Anti-Doping Agency lists BPC-157 (class S0) and TB-500 (class S2) as prohibited. This page is not legal advice; each institution's own rules apply to its lab.

For laboratory research only. Not for human or veterinary use.
