Retatrutide.

On purpose. Once a lyophilised peptide is reconstituted it slowly degrades, so a larger vial would lose potency before it could be used up — you'd be drawing weakened material by the end. A 10 mg vial is sized so a reconstituted batch stays within its usable window from the first draw to the last. It's a deliberate quality choice, not a limitation.

Every RetaNord batch is guaranteed at 99%+ identity purity. Each lot is independently tested through Veritalys, independent third-party peptide testing in the EU, 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 placed before 2pm CET typically dispatch the same business day; otherwise the next. Standard EU delivery runs 3-5 business days from fulfillment, expedited 1-2.

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.
