PRODUCT OVERVIEW
Tirzepatide Pen: Format and Specification
Tirzepatide (LY3298176) 60mg is a synthetic 39-amino-acid dual GIP/GLP-1 receptor agonist supplied to qualified researchers for controlled laboratory and analytical work. A single molecule acting on two incretin receptors places it between the single-receptor GLP-1 agonists and the triple agonists in comparative metabolic literature, which makes it the standard dual-agonist control in incretin research.
Important distinction: this is the research-grade compound, not Mounjaro. Licensed tirzepatide reaches patients as a single-use pre-filled pen with a fixed dose schedule, dispensed on prescription. What is supplied here is the raw lyophilised peptide as a laboratory reagent – no dose schedule, no prescribing information, and no approval for human use. The two are not interchangeable.
Supplied as a prepared 60mg pen, lyophilised and sealed. No reconstitution or mixing step is required before the material enters your protocol. The sealed format fixes the concentration per actuation and removes the handling variance that manual powder-and-solvent preparation introduces – diluent volume, syringe accuracy, technique and dissolution time. Each pen carries a batch reference that resolves to the specific analytical document issued for that lot.
Every batch is tested by independent HPLC for purity and by mass spectrometry for identity. Both results appear on the batch COA published on this page. A sample can read 99% pure by HPLC and still be the wrong molecule if synthesis went wrong; the mass spectrometry result is what rules that out. Always check both figures, and always confirm the batch code on the certificate matches the code on your pen label.
Store the sealed pen refrigerated at 2-8 degrees C, protected from light, and do not freeze. Avoid the fridge door – temperature cycling from opening and closing is precisely the stress that degrades peptide structure. Because the pen is a sealed prepared format, there is no reconstitution step and no prepared solution to store. Follow the conditions printed on the product label and stated in the batch documentation. Supplied strictly for laboratory research only, to buyers aged 21 or over. Not a licensed medicine and not for human or veterinary consumption.
