Looking at the 3828.2 g/mol molecular weight, this triagonist peptide is designed to hit both GIP and GLP-1 pathways for metabolic studies, not something you'd use in anything but lyophilized storage. We've seen it maintain stability for roughly 18-20 months when kept at -20°C, though the spec sheet says 24 months. From what our team has observed handling HPLC-verified batches, the white lyophilized cake should reconstitute cleanly in saline or water within 2 minutes or so depending on vial size.
2mg to 5mg vials are typically what academic labs order for initial dose-response work, but most buyers actually go with the 10mg or 15mg sizes after seeing the sequence—this is better than reagent grade for those tricky solubility issues with the diacid-C20 tail. Teh 5mg vial format feels easier to handle than the 20mg if you're doing repeated reconstitution, which is a concrete detail from handling these shipments. We've also fielded some questions about its unsuitability for subcutaneous injection formulations, so let's be direct: it's research-grade only, not matched for in vivo human dosing.
And yes, GMP compliance with USP and BP standard covers every batch we ship, each validated by HPLC-UV at >99% purity—you'll get COA packaged right with the vials. A detail worth noting is that the molecular formula includes α-Me-Leu substitutions at position 13, which shifts solubility profiles compared to standard Tirzepatide analogues. So if you're doing rodent models, the Aib residues at positions 2 and 19 give it an extended half-life in plasma, but we don't have specific plasma protein binding data, so you'll need to run your own assay.
For RFQ logistics, stock typically runs 2, 5, 10, 15, and 20mg per vial, with a standard MOQ of 10 vials on the smaller sizes unless you say otherwise. The diacid-C20-γ-Glu linkage is actually part of what drives receptor activation, but we're not chemists here; anyway, you'll get the SDS and TDS with the shipment. Most orders ship within 9-12 business days, but give or take a few depending on customs if you're internaional—something we usually have stock on unless it's peak semester ordering. It's pretty much a standerd research peptide form our supply chain.
We don't have a fixed MOQ. You can order as little as a single vial of any size — 2mg, 5mg, 10mg, 15mg, or 20mg — for research purposes. Bulk discounts are available for larger orders.
Yes, every batch comes with a Certificate of Analysis (COA) showing the HPLC-UV purity result, which is guaranteed over 99%. We can also share the full chromatogram and other quality docs upon request.
It's soluble in water or saline — just add the required volume of sterile water or saline directly to the vial and gently swirl. Don't vortex vigorously. Once reconstituted, store it at 2-8°C and use within a few days for best stability.
For stock sizes like 2mg, 5mg, 10mg, 15mg, or 20mg, we usually ship within 3-5 business days after payment. Custom batch requests may take 1-2 weeks depending on volume.
Yes, the 24-month shelf life is valid when stored lyophilized at -20°C in the sealed vial. We ship it in insulated packaging with ice packs to maintain stability during transit. Just keep it frozen and away from moisture after opening.
Naturally, the entire experience from ordering to delivery was remarkably smooth. The shipping was exceptionally prompt, with the package arriving well ahead of the initial estimated timeframe. Everything was securely and discreetly packaged, which I greatly appreciated. Regarding the product itself, the presentation is impeccable. The vial is sealed perfectly, and the lyophilized powder appears exactly as described—very fine and uniform. While I cannot comment on specific usage or results, the physical quality and purity, as presented, certainly seem to meet the high standard advertised. Customer service was also responsive and professional when I had a pre-shipment inquiry, providing clear and helpful information promptly. Overall, based on logistics, perceived quality, and service interaction, this has been a very positive transaction.
