So we’re ordering teh bulk batch of the 2023788-19-2 peptide, the one listed as Xcel Semaglutide but also often known as Tirzepatide — basically it’s a dual GLP-1/GIP analog, and the CAS is what locks it in for our records.
Purity is listed at ≥99% by HPLC, which is better than reagent grade for this kind of metabolic work, and we’ve got the COA form the last batch showing 99.2% if anyone wants to double-check.
it come as a in 10mg vials, 10 per box, and we usually have stock but confirm lead time — most buyers go with the 10mg size for reconstitution, and the 15mg or 30mg vials are also availble if needed later.

Storage is straightforward: keep it dry and dark at 0-4°C short term or -20°C for longer, and the shelf life is over two years when stored properly, though we typically rotate stock within 20 days or so of dilevery anyway.
One thing it’s not suited for is any in vivo use beyond research — it’s strictly for lab assays and cell work, and the powder can be a bit tricky to handle if you don’t let it warm to room temp before opening (don’t ask how I know that).
We’re ordering 50 vials to start, payment via wire, and the MOQ was no issue for this suplier — they’ll ship within 5-7 business days after the COA is confirmed.
For bulk orders, we typically start at 100 vials per batch, but we can discuss smaller quantities if you're just testing the product. Just reach out to us with your volume.
Lead time is usually 7-14 business days after payment confirmation, depending on the quantity. We can expedite if needed, but that may affect pricing.
Yes, we include a COA for every batch, showing the HPLC purity of ≥99% and other specs. It's standard with all orders.
We can adjust vial sizes for bulk orders, but it requires a minimum volume commitment. Let us know your target dosage, and we'll check feasibility.
Store it in a dry, dark place at -20°C for long-term stability. For short-term use, 0-4°C is fine, but avoid freeze-thaw cycles to keep the lyophilized powder intact.
Zippy delivery and zero issues with the shipping process. My order arrived ahead of schedule, which was a pleasant surprise. The packaging was secure and discreet, exactly as promised. As for the product itself, the quality appears top-notch based on initial inspection; everything was sealed properly and labeled clearly. Customer service was also responsive when I had a pre-order inquiry—they answered promptly and professionally. Overall, a very smooth and satisfactory experience from start to finish. Would definitely consider ordering again for future needs. Highly recommend this supplier for their efficiency and reliability.
