Tirzepatide
Dual GIP/GLP-1 receptor agonist · Lyophilized powder · 5mg & 10mg vials
For in vitro and laboratory research use only.
What exactly is Tirzepatide?
Good question. Tirzepatide is a synthetic peptide. It acts on two receptors at once, GIP and GLP-1. So it’s called a dual agonist. First, it was developed for metabolic research. Also, it contains a C18 fatty acid chain. That chain allows it to bind albumin. Therefore, it stays active longer than most peptides. The amino acid sequence is 39 residues long.
Is Tirzepatide tested at globalpeptidesofficial.com?
Yes. Every batch goes through Janoshik Analytical. They’re an independent lab. We don’t test in-house. So there’s no conflict. First, they run HPLC to check purity. Next, they verify mass by spectrometry. Finally, they issue a Certificate of Analysis. You get that COA with your order. However, you should always verify with your own lab too. We make this easy — just ask us for the batch-specific report.

How should Tirzepatide be stored and handled?
Storage matters a lot. First, keep the lyophilized vial at 20°C. Also, keep it away from light. But once you reconstitute it, move it to 2–8°C. Next, use bacteriostatic water for reconstitution. This keeps it stable longer. However, avoid freeze-thaw cycles. Each cycle degrades the peptide. So aliquot before freezing if you need multiple uses. Finally, work in a sterile environment. Standard lab protocols apply.
Why choose globalpeptidesofficial.com for this peptide?
We don’t test in-house. That’s intentional. Janoshik is independent. So there’s no bias. Also, we publish the COA openly not just on request. However, purity alone isn’t enough. Therefore we also verify the sequence by mass spec. First-time buyers get the same standards as repeat customers. Finally, we ship lyophilized. So stability during transit isn’t a concern. No filler, no hype just documented, traceable peptides for serious research.
