The single compound at the centre of today's metabolic and obesity research. 99%+ identity purity, third-party HPLC tested, with a Certificate of Analysis in every box.
Three commitments we put in writing — and on the box.
Every production batch is independently analyzed before it leaves our facility. Anything below the spec gets destroyed, never reworked.
Lost, damaged, or stolen in transit? We replace it free. Every order is automatically covered, no add-on cart fee.
A full Certificate of Analysis ships with each order — HPLC trace, mass spec verification, and the lot number printed on your vial.
EU-stocked and dispatched. Every batch undergoes third-party identity and content testing. Documented quality and research-grade pricing — kept simple so the right materials stay accessible.
OrderOur core catalog ships same-day. No backorders, no waitlist surprises, no calls from procurement asking when the vials are arriving.
Per-vial cost drops at higher quantities. Lab bundles unlock additional documentation and a named account contact.
Unmarked, sealed packaging with full tracking on every order. Cold packs added automatically when ambient temperatures call for it.
Most EU orders dispatch within 24 hours. Expedited shipping pushes that to 1-2 day delivery for most addresses across Europe.
Lot-specific CoAs, mass spec traces, and HPLC chromatograms — published and searchable by batch ID, not buried in support tickets.
Optional access to peer protocols, study summaries, and discussion threads with other researchers running comparable work.
Five rounds of testing before a product earns the RetaNord label. The same standard applied to your first order and your fiftieth.
Every lot enters our analytical workflow before it ships. If a single check fails, the whole batch is held until the cause is identified — or destroyed. Your CoA isn't a marketing artifact; it's the record of work we already did.
Each vial is tested to confirm it contains exactly what the label states, down to the microgram.
Identity and purity confirmed against the target structure. Synthesis byproducts and degradation products screened out.
Formulation and pH ranges validated so the lyophilized product stays intact across its shelf life.
Third-party sterility and endotoxin testing screens for bacteria, fungi, and bacterial toxins.
Precision weighing, sealing, and lot tracking enforce the same quality bar from lot to lot.
Every RetaNord vial ships with the chromatogram, mass spec result, and lot ID printed on its own Certificate of Analysis. Nothing to take on faith — verify the math, every time.

Dosage reference, step-by-step reconstitution, the week-by-week protocol, safety notes, the evidence base and full specifications — everything this overview only touches on.
One receptor versus the triple-agonist researchers call the next generation.

Phase-2 trial data: retatrutide ≈24.2% body weight at 48 weeks (NEJM 2023); semaglutide ≈14.9% at 68 weeks (STEP-1). Separate studies, different populations and durations. Ozempic® is a registered trademark of Novo Nordisk A/S; RetaNord is not affiliated with or endorsed by Novo Nordisk. Supplied for laboratory research use only.
Week by week — press play or drag the slider.
Commonly reported in research and by self-experimenters — individual results vary and are not guaranteed. Research use only · not medical advice.
Documented, verified material — and the calm, energetic routine researchers build around it.
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 at accredited European labs using HPLC for purity quantification and mass spectrometry for identity confirmation. 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 via mass spec, 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. Every shipment includes free shipment protection — if it arrives damaged or doesn't arrive at all, we replace it.
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.
RetaNord is a US-based research peptide supplier focused on documentation and consistency. Our products are manufactured in-house and independently verified at accredited European labs. Every order ships with a lot-specific CoA, every claim we make is reflected in published test data, and our quality procedures are documented and reviewable.
No. All RetaNord products are sold strictly for laboratory research and educational purposes. They are not approved for human consumption, veterinary use, or any therapeutic application. Placing an order is a confirmation that you are a qualified researcher and will handle materials in accordance with applicable laws and standards.
Every order is covered by free shipment protection. If a vial arrives damaged or a package is lost or stolen in transit, send us photos and tracking details within 48 hours of the delivery date and we'll send a one-time replacement. Reconstituted product is not eligible for return.
