RetaNord: we test for more than purity.

Single vials of Retatrutide are 10 mg, and you can buy 1 or more: the more vials, the lower the price per vial. For larger amounts, Retatrutide also comes in kits of 10 or 30 vials with 20 mg or 40 mg per vial.

Every RetaNord batch is guaranteed at 99%+ identity purity. Each lot is tested through Veritalys, an EU peptide testing service, using HPLC for purity and content, with identity confirmed against a reference standard. A Certificate of Analysis is included with every order showing the exact figures and the lot-specific chromatogram.

The CoA is a signed lab document tied to your specific lot. It includes purity percentage (target 99%+), identity confirmation against a reference standard, physical appearance, and endotoxin levels (target below 1 EU/mg). The lot number on your vial matches the lot ID on the document, so you can verify what you received against what was tested.

Sealed lyophilized vials are stable at room temperature for short-term storage (under 3 months) in a cool, dry, dark place. For longer storage, refrigerate at 2-8°C or freeze at -20°C. Avoid repeat freeze-thaw cycles. Stored correctly, lyophilized peptides typically remain stable for 2+ years.

Orders are dispatched within 24–48 hours from Germany, Austria or Estonia. Delivery across the EU takes 3–4 business days from your order, tracked to your door or a parcel locker.

RetaNord ships across all EU member states. Availability outside the EU depends on local customs regulations for research materials; reach out to support with your destination country and we'll confirm what we can do.
