The BulkGLP 20mg Retatrutide Research Pen offers unparalleled precision and convenience for laboratory applications. Each pen is pre-filled with a precisely measured, reconstituted Retatrutide solution, prepared in-house using our HPLC-verified peptide and sterile bacteriostatic water. This ready-to-use format eliminates the variables of manual reconstitution, ensuring consistency and simplifying repeatable microdosing protocols for metabolic and receptor pathway research.

Product Details & Technical Specifications

This product provides the triple-agonist peptide Retatrutide (LY3437943), which targets the GLP-1, GIP, and glucagon receptors. Each batch is subject to rigorous quality control to ensure identity and purity.

Research Protocol & Safety Advisory

This product contains a pure, reconstituted Retatrutide solution with no excipients. Researchers may observe different uptake rates and receptor activity compared to lyophilized powders or filler-based preparations. It is recommended to begin all experiments with low, microdose-level volumes to establish a baseline. Do not assume equivalence to compounds or vials sourced externally.
