Actually went with the 99.7% purity grade since our last batch of research-grade peptide from a different suplier had some pretty noticeable variation in the HPLC data, and that's just not acceptable when you're working with doses in the nanomolar range — we usually have stock, but confirm lead time if you need more than 50 vials or so. The molecular weight is 4813 g/mol and the CAS is 2023788-19-2 if you're plugging it into an existing protocol, and it comes as a in 10-vial boxes.
Most of the teams we work with are using it for metabolic studies and weight management models, but I've seen some labs push it into GLP-1 receptor work that's totally separate from usual application. Basically, this isn't something you'd use for cell-free assays where solubility is critical — the powder needs cold storage at 2-8°C and it's light-sensitive, so handle that before opening.
One thing that caught my eye is the batch-to-batch consistency they claim in the COA; we got burned before with a supplier whose purity drifted about 1.5% between lots, and that throws off for weeks. Also, the packaging is standard vials with proper labeling, no custom blister packs or anything fancy, but that keeps the MOQ reasonable at around 20 boxes for bulk pricing.
The bulk order situation is pretty straightforward: you can order in 10-vial increments (check lead time for internaional shipping, which is usually 2-4 weeks), and if you need OEM services like custom labeling or different vial sizes, they'll do that but you'll need to call in the order directly. I'd say 99.7% is better than reagent grade for this type of research, but confirm that the HPLC method used matches your internal standerds.
For storage, they specify 2-8°C protected from light, but what some people don't realize is that repeated freeze-thaw cycles degrade this stuff noticeably — we usually aliquot into smaller tubes right after reconstitution. The molecular formula is C225H348N48O68, and I've seen some protocols that recommend using it within 30 days of reconstitution at that temperature, though that's not on teh supplier's SDS.
Anyway, pricing wasn't the main driver — the 99.7% purity and the detailed analytical docs were, since our compliance team wants to see HPLC and mass spec traces for every lot we recieve. 2-8°C shipping is handled by ice packs and insulated containers, which adds maybe $50-80 to the freight cost, but you'll want to confirm that for your destination.
Our MOQ for Tirzepatide is one box, which contains 10 vials. We can adjust this for larger custom orders, just contact us.
For standard orders, lead time is 3-5 business days after payment confirmation. Bulk or OEM orders may take 7-10 days depending on quantity and packaging specs.
Yes, we include a COA with every batch of Tirzepatide, verifying the 99.7% purity and other specs like appearance and molecular weight. Just request it with your order.
Store it at 2-8°C (refrigerated) and protect it from light. Keep it in the original packaging until use to ensure the white powder stays stable.
Absolutely, we provide OEM services for Tirzepatide. You can customize the packaging, labels, and vial count per box—just share your requirements and we'll handle the rest.
