About Retatrutide 10 mg

Retatrutide (LY3437943) is a synthetic 39-amino-acid peptide designed as a triple agonist at the GIP (glucose-dependent insulinotropic polypeptide), GLP-1 (glucagon-like peptide-1), and Glucagon receptors. Identity and purity are verified by mass spectrometry and reverse-phase HPLC, with individual results reported in the Certificate of Analysis (CoA) for each batch.

Initial characterization of the compound was published by Coskun and colleagues in Cell Metabolism (2022) [1], and preclinical data from the research program are registered in peer-reviewed scientific literature and the public trials registry [2].

MX-1 Labs distributes Retatrutide 10 mg in Mexico as a scientific research compound with laboratory packaging, an auditable batch number, and complete per-vial analytical documentation. The product is intended exclusively for in vitro laboratory research; it is not a medication, supplement, or consumer product.

Research applications

Retatrutide acts simultaneously on three well-characterized G protein-coupled receptors in endocrinological literature: GIP, GLP-1, and the Glucagon receptor [1]. In preclinical models, combined activation of the first two is associated with effects on satiety, insulin sensitivity, and energy expenditure, while the glucagon component distinguishes Retatrutide from classical dual agonists by engaging hepatic lipolysis as an additional mechanism. The peptide structure includes non-canonical amino acid modifications and conjugation with a fatty acid to extend the plasma half-life observed in pharmacokinetic studies. The specific experimental application is the responsibility of the receiving lab and its authorized institutional SOP.

Storage and handling

Sealed vial: store protected from light, humidity, and prolonged air exposure per the batch documentation. Once the experimental solution is prepared, keep refrigerated under documented conditions when the lab protocol requires it; record the preparation date, diluent used, and workstation conditions. Stability of the prepared solution depends on the batch-specific CoA, the diluent, aseptic technique, and the research protocol. Discard the material at any sign of turbidity, suspended particles, or any color change from the initial observation.

Frequently asked questions

Is it legal to buy research peptides in Mexico?

Yes. Research peptides are sold legally in Mexico strictly for laboratory research use — not for human or veterinary consumption, diagnosis, or treatment. MX-1 Labs sells for research purposes only; at checkout you confirm compliant use under applicable law (COFEPRIS) and your lab's protocols. Nationwide shipping from CDMX.
