Buy research peptides in Europe — HPLC certified purity 99%+

MyPeptide.eu is a European platform specializing in the supply of high-purity research peptides. Our catalog covers four categories of molecules:GLP-1/GIP/Glucagon agonists (Retatrutide R3), THEcopper peptides and cell regeneration(GHK-Cu), themetabolic coenzymes(NAD+) and thereconstitution solutions(bacteriostatic water). Each batch is analyzed by Janoshik Analytical, an accredited independent laboratory, with a certificate of analysis (COA) available for each batch.

Our products are intended exclusively for scientific laboratory research. They are not approved for human consumption. Shipping from the European Union within 48–72 hours to France, Belgium, Luxembourg, Germany, the Netherlands, Spain, Italy, Poland, and Portugal.

Lyophilization and peptide stability — what our process guarantees

All peptides in the MyPeptide catalog are provided in the formfreeze-driedThis maximizes long-term stability. Lyophilization removes free water through sublimation under vacuum, halting the hydrolysis and oxidation reactions that degrade peptide bonds. A properly stored lyophilized peptide at −20 °C retains its structural integrity for a minimum of 24 months.

After reconstitution withbacteriostatic water(0.9% benzyl alcohol), the solution can be stored for 4 to 8 weeks at +4°C. Avoid repeated freeze/thaw cycles: each cycle generates thermal shocks that can fragment peptide chains and reduce effective purity. For long-term protocols, aliquot before freezing.

La HPLC purity ≥99%Certified by Janoshik, the quality is measured by reversed-phase high-performance liquid chromatography (RP-HPLC), the international reference method for characterizing synthetic peptides. It excludes sequence impurities, oxidation products, and synthesis contaminants.

Frequently asked questions about purchasing research peptides

What is the difference between Retatrutide R3 10mg and 20mg?
Le Retatrutide 10mgis suitable for titration protocols and experiments on small animal models.Retatrutide 20mgSuitable for longer protocols or studies requiring higher doses. Both formats offer batch-certified HPLC purity ≥99%. Compare formats, prices, and clinical results on our page.retatrutide France.
Does GHK-Cu act differently from BPC-157 on tissue regeneration?
Le GHK-CuBPC-157 is an endogenous tripeptide that modulates gene expression by activating over 4,000 genes involved in cell repair and collagen synthesis. Its mechanism is primarily epigenetic. BPC-157 acts more directly on the VEGF pathway and muscle and tendon regeneration. These two targets are complementary in wound healing research.
How to verify the authenticity of Janoshik analysis certificates?
Each Janoshik COA carries a unique batch identifier that can be verified directly on the Janoshik Analytical portal. All our reports are published on the pagecertificates of analysisIf in doubt, contactcontact@mypeptide.euwith the batch reference.
