Retatrutide is an investigational peptide compound classified as a triple-agonist due to its activity at three receptor targets: GLP-1R (glucagon-like peptide-1 receptor), GIPR (glucose-dependent insulinotropic polypeptide receptor), and GCGR (glucagon receptor). This triple-receptor pharmacology distinguishes it from earlier dual-agonist compounds and has made it a subject of significant interest in metabolic research.
Research into Retatrutide has focused on characterizing how simultaneous agonism at all three receptor types influences metabolic signaling in pre-clinical models. Each receptor target is associated with distinct metabolic effects at the cellular and systemic level — GLP-1R and GIPR with incretin biology, and GCGR with hepatic metabolic processes. Understanding how these three pathways interact under combined agonist activity is a key question driving current research.
As a novel compound, Retatrutide research is still in relatively early stages compared to single- or dual-agonist peptides. Pre-clinical studies have explored its receptor binding profile, downstream signaling cascades, and comparative pharmacology against related compounds, providing a growing body of data for metabolic research laboratories.

Frequently asked
8 questionsHow fast is delivery and which carriers do you use?
Orders placed before 16:00 CET ship the same business day from the Netherlands via DPD or PostNL. EU-wide delivery typically takes 2–5 working days, fully tracked. Every parcel ships in plain, unbranded packaging with no peptide-related markings visible.
Which payment methods do you accept?
We accept iDEAL (Netherlands), Bancontact (Belgium), PayPal, Klarna pay-later, SEPA instant bank transfer, and Visa/Mastercard credit and debit cards. All payments are processed through PCI-DSS-compliant European processors. Bank transfer and card orders ship within 24 hours of payment confirmation.
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.
What is Retatrutide as a research peptide?
Retatrutide is a synthetic tri-agonist peptide studied in laboratory research for its simultaneous activity at GIP, GLP-1, and glucagon receptors. It has a molecular weight of approximately 4,539 Da. Retatrutide has not been approved by the EMA, FDA, or any national medicines authority and is sold by my\PEPT.eu for in-vitro research use only.
How should Retatrutide be stored?
Lyophilized Retatrutide is stable for up to 24 months at −20 °C in a sealed vial, away from light and moisture. Once reconstituted in bacteriostatic water, refrigerate at 2–8 °C. This compound is intended for laboratory research only.
What does the Certificate of Analysis show for Retatrutide?
The batch-specific CoA for Retatrutide shows HPLC purity of 99 % or higher, identity confirmation by high-resolution mass spectrometry, batch number, and net peptide content. The CoA is downloadable from the product page. This compound is not for human or veterinary consumption.
