Trustpilot⚠ Research Use Only
Not for human consumption, veterinary use, or clinical administration. Sold exclusively to qualified laboratories and researchers for in-vitro study.
Supplied as a matched two-vial format, the Reta Duo is intended for laboratories running extended or parallel Retatrutide investigations that would otherwise consume a single vial too quickly. Each vial arrives as a lyophilised powder with its own batch-level certificate of analysis, so purity and identity can be traced independently even when both are drawn from the same shipment. It is offered strictly as a research reagent — not for human consumption or injection, and carrying no therapeutic or dosing guidance of any kind.

How do you verify peptide purity?
Every batch is HPLC-tested to 99% purity or higher by an independent third-party laboratory, with identity confirmed by mass spectrometry. The batch-specific Certificate of Analysis is published on every product page and delivered with the order.
Are research peptides legal to buy in the Netherlands and EU?
Yes — when sold and purchased strictly for in-vitro laboratory research. Research peptides on my\PEPT.eu are not approved, marketed or intended for human or veterinary use, medical diagnosis or therapeutic application. By placing an order you confirm research-only intent and accept responsibility for compliance with local regulations.
How should research peptides be stored?
Lyophilized (freeze-dried) peptides keep up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight.
