Is It Legal to Buy Peptides? Research Peptides and the Legal Situation in DE, AT, CH

Whether peptides can be bought legally cannot be answered across the board: research peptides are chemical substances whose legal classification depends on the specific substance, its presentation, and the intended use. In Germany, the key laws are above all the Medicinal Products Act, narcotics and NpS law, and, in sport, the Anti-Doping Act.

This article provides an objective overview of the most important legal frameworks in Germany, Austria, and Switzerland. It shows which terms and lists are decisive, what the “Research Use Only” label means – and what it does not do. Every legal statement is linked to the official legal text or the official list so that you can read it yourself.

Not legal advice: This article is general, non-exhaustive information as of October 2026. It does not replace individual advice from a lawyer. Laws and lists change; only the current official version is binding. Anyone who wants to obtain peptides for research purposes is obliged to check the legal situation applicable to them on their own responsibility.

Is it legal to buy peptides? Why there is no blanket answer

Peptides are short chains of amino acids (the basics are covered in the article What are peptides?). Legally, however, “peptide” is not a category of its own. Depending on the substance and context, a peptide can be a laboratory reagent, the active ingredient of an approved medicinal product, a substance on an anti-doping list, or none of these. Which rules apply follows from several test questions:

• Which substance exactly? Individual substances are named on lists (e.g., the annexes of the BtMG or AntiDopG), others are not.
• How is it presented and advertised? If a product is presented with healing promises or instructions for use in humans, it moves closer to the definition of a medicinal product.
• What is it used for? In vitro research, use in humans, and doping in sport are completely different matters from a legal perspective.
• Where are you located? Germany, Austria, and Switzerland each have their own law; additional rules apply when bringing goods across borders.

That is why statements such as “peptides are legal” or “peptides are banned” cannot be upheld in such general terms. The only sound approach is a case-by-case assessment along the following legal frameworks.

Germany: the Medicinal Products Act and the definition of a medicinal product

What is a medicinal product under the AMG?

The key provision is § 2 of the Medicinal Products Act (AMG). According to it, medicinal products are substances or preparations of substances that are intended for use in or on the human body and are intended as agents with properties for curing, alleviating, or preventing human diseases – or that can be used in or on the human body in order to restore, correct, or influence physiological functions through a pharmacological, immunological, or metabolic action, or to make a medical diagnosis.^[1]

This results in two perspectives, often referred to in practice as “medicinal products by presentation” and “medicinal products by function”: on the one hand, it depends on how a product is presented (intended purpose, presentation, advertising claims); on the other, on which properties the substance objectively has. § 2(3a) AMG also clarifies that a product that, taking all its properties into account, meets the definition of a medicinal product is considered a medicinal product even if it could also fall under another product category.^[1]

What this means for research peptides

A peptide that is expressly offered for in vitro research, without healing promises, without dosing information, and without instructions for use in humans, is presented differently from a product that contains exactly such information. However, presentation alone is not conclusive – the legal assessment remains an overall consideration of the individual case. As soon as a substance is intended for use in humans or is advertised accordingly, medicinal products law with its rules on approval, manufacturing, and distribution may apply.

Bringing goods into Germany (intra-EU movement of goods)

Within the EU, the free movement of goods applies in principle. For medicinal products, however, § 73 of the AMG contains a separate prohibition on bringing them into Germany: medicinal products requiring approval may only be brought into Germany under certain conditions, for example if they are approved or registered here and go to certain recipients; paragraph 2 provides for narrowly defined exceptions.^[2] Whether § 73 AMG applies at all again depends on whether the specific product is to be classified as a medicinal product – i.e., on substance, presentation, and purpose.

BtMG and NpSG: listing principle instead of a blanket ban

The Narcotics Act (BtMG) works on a listing principle: narcotics within the meaning of the act are the substances and preparations listed in Annexes I to III. The German federal government can amend these annexes by ordinance.^[3] Whether a substance is covered can therefore only be checked against the current annexes.

The New Psychoactive Substances Act (NpSG) supplements this with substance groups. Under § 2 NpSG, a “new psychoactive substance” is a substance from one of the substance groups listed in Annex 1 or a substance listed in Annex 2 with the properties described there.^[4] The substance groups in Annex 1 are defined chemically – for example compounds derived from 2-phenethylamine or tryptamine, synthetic cannabinoids, or benzodiazepines.^[5]

For most research peptides, these two laws are therefore not the first point to check. Their relevance cannot be ruled out, however: what always matters is comparing the specific substance against the current annexes.

Anti-Doping Act and the WADA list: peptides in sport

What the AntiDopG regulates

The Anti-Doping Act (AntiDopG) is tied to the purpose of “doping in humans in sport.” § 2(1) prohibits, among other things, manufacturing, trading in, supplying, or prescribing doping agents for this purpose; paragraph 2 prohibits their use on another person. Paragraph 3 prohibits acquiring, possessing, or bringing into Germany certain doping agents in non-small quantities for the purpose of doping.^[6]

Under “peptide hormones, growth factors, related substances, and mimetics,” the Annex to the AntiDopG lists, among others, erythropoiesis-stimulating agents, growth hormone-releasing peptides such as GHRP-2, GHRP-6, or ipamorelin, and, among the growth factors, also thymosin β4 and its derivatives, e.g., TB-500.^[6] You'll find more on the research context of TB-500 in the article TB-500 and thymosin β4.

The WADA Prohibited List

For athletes in organized sport, the Prohibited List of the World Anti-Doping Agency (WADA) is also authoritative. It is revised annually, enters into force on January 1 each year, and is published three months in advance.^[8] In the 2026 list, class S0 (“Non-approved substances”) covers any pharmacological substance that is not approved by any governmental health authority for human therapeutic use and is not addressed in another class – it is prohibited at all times. BPC-157 is expressly named there as an example; thymosin β4 and derivatives such as TB-500 are in class S2.^[7]

This list is not a criminal law for the general public but a set of rules for sport. For research outside of sport, it is nevertheless important context, because it shows how many peptides are under regulatory scrutiny.

Austria and Switzerland: separate legal frameworks

Austria

The Austrian Medicinal Products Act, in § 1(1), likewise defines medicinal products as substances or preparations of substances intended for use in or on the human body and for curing, alleviating, or preventing diseases, or that can restore, correct, or influence physiological functions or serve as the basis for a medical diagnosis.^[9] In sport, the Federal Anti-Doping Act 2021 (ADBG 2021) governs the anti-doping provisions and refers to the reference list of the Anti-Doping Convention.^[10] Other special laws may also apply; a case-by-case assessment remains necessary.

Switzerland

In Switzerland, the Therapeutic Products Act (HMG, SR 812.21) governs medicinal products and medical devices; the competent authority is Swissmedic. Under Art. 4(1)(a) HMG, medicinal products are products of chemical or biological origin that are intended or claimed to have a medical effect on the human or animal organism.^[11] So here, too, the way a product is advertised plays a role. Important: SunPept does not ship to Switzerland.

Legal frameworks at a glance

What “Research Use Only” means – and what it doesn't

“Research Use Only” (RUO) is a label of the intended use: the substance is intended for scientific research, typically in the in vitro laboratory – not for human or veterinary use, not as a medicinal product, food, or cosmetic. At SunPept, you confirm this purpose at checkout; you'll find details on the page Research Use Only.

What RUO is not — an official authorization or a “free pass.” The label does not change the fact that a substance may be on a statutory list, and it offers no protection if a product is actually intended for use in humans or is used that way. Precisely because the definition of a medicinal product is tied to intended purpose and presentation, a credible RUO offering consistently refrains from healing promises, dosages, and instructions for use.

Checking credibility: a checklist before sourcing for research

Regardless of the legal classification, it is worth taking a structured look at the supplier. These points are good indicators:

• Complete legal notice: Company name, legal form, address, and registration details must be identifiable. SunPept is operated by Mokapoko s.r.o., based in Prague.
• Traceable analysis reports: Independent laboratory analyses should be viewable per product. SunPept links available Janoshik reports at Test reports; for some products, analysis documentation is available on request.
• No healing or efficacy promises: Suppliers who advertise research peptides with health promises, dosing schedules, or testimonials call their own RUO labeling into question.
• Clear purchasing terms: Transparent payment method (prepayment at SunPept), shipping route (EU shipping from the Czech Republic), and an explicit RUO confirmation.
• No blanket statements about legality: Anyone who promises “100% legal” oversimplifies a legal situation that depends on the individual case.

Frequently asked questions

Is it legal to buy peptides in Germany?

There is no blanket answer. Whether obtaining a peptide is legally permissible depends on the specific substance, its presentation, and the intended use. Particularly relevant are the AMG, BtMG, NpSG and – in sport – the AntiDopG. This article is not legal advice; if in doubt, you should seek advice from a lawyer.

Does the “Research Use Only” label automatically make a purchase permissible?

No. “Research Use Only” only describes the intended use, namely scientific research without use in humans or animals. The label is not an official authorization and does not change whether a substance appears on a statutory list or whether it is to be classified as a medicinal product in an individual case.

When can a peptide be considered a medicinal product?

Under § 2 AMG, what matters is whether a substance is intended for use in humans and is presented as a means of curing, alleviating, or preventing disease – or whether it can influence physiological functions through a pharmacological, immunological, or metabolic action. Presentation, advertising claims, and actual intended use play an important role here.

Are peptides on the doping list?

Some are. The Annex to the German Anti-Doping Act lists, among others, growth hormone-releasing peptides as well as thymosin β4 and derivatives such as TB-500. The 2026 WADA Prohibited List names BPC-157 as an example in class S0. For athletes in organized sport, the current WADA list is binding.

What is the situation in Austria?

Austria has its own Medicinal Products Act, whose definition of a medicinal product is likewise linked to use on the human body and to curative or functional purposes. In sport, the Federal Anti-Doping Act 2021 applies. In Austria, too, classification depends on the specific substance and the purpose; you are responsible for checking the legal situation yourself.

Does SunPept ship to Switzerland?

No, SunPept does not currently ship to Switzerland. In Switzerland, medicinal products are regulated by the Therapeutic Products Act (HMG); the competent authority is Swissmedic. Under Art. 4 HMG, products that are advertised for medical action are also considered medicinal products. SunPept ships exclusively to the EU countries it serves.

Do I need a permit for research peptides?

Whether a permit or authorization is required depends on the specific substance, the intended use, and the research setting, for example whether an institution, a laboratory, or a private individual is involved. A generally valid answer is not possible. If in doubt, you should seek legal advice before ordering.
