All Research Peptides

The range by research area

The range follows the fields in which the compounds are studied. Each field has its own collection, and this page shows all of them together:

• Tissue models: BPC-157 (5 and 10 mg), TB-500 (5 and 10 mg) and the BPC-157 and TB-500 blend with 10 mg of each. See BPC-157 and TB-500 research peptides.
• Incretin receptor research: Semaglutide (GLP-1), Tirzepatide (GLP-1 and GIP) and Retatrutide (GLP-1, GIP and glucagon). See GLP-1 and metabolic research peptides.
• Ghrelin receptor research: Ipamorelin (5 and 10 mg), a selective GHS-R1a agonist.
• Telomerase and circadian research: Epitalon 100 mg, the tetrapeptide Ala-Glu-Asp-Gly.

Buy research peptides: vial sizes, form and lot number

Most compounds are available in several vial sizes, from 2 mg to 30 mg. The right size depends on how much your protocol uses within a short period after reconstitution, because the solution is much less stable than the powder. Several small vials keep more of a compound as dry powder than one large vial that is opened early. Each product page lists the compound class, the sequence or length, the molecular weight, the amount per vial and the research fields. The lot number on the label links every vial to its batch.

Research peptide supplier in the EU: what you can check

Before you order from any supplier of research peptides, three things can be checked without trusting a marketing claim: whether the company is registered and issues invoices with VAT, whether a batch report exists for the lot you receive, and whether the product arrives as sealed lyophilised powder with the amount on the label. We publish the company details in the imprint, ship sealed vials with lot numbers and provide the batch report on request. Our customer service team answers questions about a specific lot; the contact link is in the footer.

Certificate of analysis: what the documentation shows

A label states what should be in a vial. A certificate of analysis shows what is in it. Products with a certificate on file are marked "COA on file" and collected under peptides with certificate of analysis. For documented batches, the certificate reports identity by mass spectrometry, purity by HPLC and the lot number that matches your vial. Not every product carries a certificate, and we do not state purity figures where no report exists. Our guide on mass spectrometry and HPLC explains what each test shows.

Storage and transport of lyophilised peptides

Lyophilised peptides are stable at -20 °C for long-term storage and at 2 to 8 °C for a few weeks, dry and protected from light. Once reconstituted with bacteriostatic water, a solution should be kept refrigerated and used within a short period. Repeated freezing and thawing reduces stability. The sealed powder needs no cooling in transit. Details on handling are in our research peptide FAQ.

Are research peptides legal to buy?

The products in this range are research chemicals for laboratory use, not authorised medicines. Semaglutide and Tirzepatide exist as active substances in authorised medicines, but the lyophilised research compounds on this page are not those medicines and have no authorisation of their own. As of October 2026, none of the compounds is listed in annexes I to III of the German Narcotics Act (BtMG) or in the New Psychoactive Substances Act (NpSG). If the competent authority classifies a parcel as a medicine, the import ban of section 73(1) of the German Medicines Act applies. A research chemical may not be used in humans or animals anywhere. Our guide What are peptides? explains how research peptides are classified.
