We’re looking at your catalog inquiry on the tirzepatide, and the 5mg, 10mg, 15mg, and 30mg vials are what we stock most often, usually shipping within a week or so once the order clears. It’s a dual agonist working on both GIP and GLP-1 receptors, pretty much mimicking natural hormones to regulate glucose and appetite in metabolic research models — that’s the core mechanism we see labs focusing on.
The problem it solves is the need for sustained receptor activation without constant redosing, since the peptide’s half-life is longer than most single agonists. We’ve had clients report it handles that well in rodent studies, but it’s not ideal for acute, short-term assays where you’d want something faster-acting. Actually, the 30mg option is better for multi-week protocols, while teh 5mg vial works for pilot experiments.
Purity runs at 99.9% or higher by HPLC, and we include a COA with each batch — the CAS is 2023788-19-2, molecular weight roughly 4813.4 Da, and it’s a white to off-white powder that dissolves easily in water. Storage is critical at -20°C protected from light, or you’ll see degradation in about 20 days or so at room temp, which is a detail some buyers miss but we flag upfront.
We follow GMP guidelines for production, so traceability is solid from raw materail to the sealed vial, and the appearance is consistent batch-to-batch — something we verify with MS and amino acid analysis. Most buyers go with the 10mg vial for standard dosing, but custom packaging is availble if you need a different size, though lead time might shift to 3-4 weeks for non-standerd runs.
One thing we know from handling this peptide is that the solubility is straightforward in water, but avoid adding any buffers until after reconstitution, or you’ll get clumping. It’s not suited for oral administration at all — injection-only in research contexts — and we typically have stock for the common sizes, but confirm lead time for the 30mg if you need a large quantty.
We don't have a fixed MOQ — you can order as little as a single vial of any strength. For custom packaging, we just ask that you reach out to confirm minimums.
Yes, every shipment includes a CoA that shows the actual purity results for that batch, along with other specs like appearance and solubility. It's standard with all orders.
Keep it at -20°C in a freezer, and make sure it's protected from light — ideally in the original amber vial or a light-resistant container. That'll maintain stability long-term.
Absolutely, we can do custom fill amounts. Just let us know what quantity per vial you need, and we'll adjust the packaging accordingly — no problem.
For standard stock sizes like the 30mg, lead time is usually 3-5 business days. If you need a custom fill or larger volume, it might stretch to 7-10 days depending on the batch schedule.
