We're responding to your RFQ for the tirzepatide powder, and we've got the 2mg, 5mg, 10mg, and 15mg vials in stock right now — purity's confirmed at 99.0% or better by HPLC, with single impurities under 1.0%. 2. Moisture content is capped at 10.0% max, peptide content hits 80.0% minimum, and the molecular weight is 4813.45; solubility runs about 3 mg/mL in DMSO, which is 0.73 mM for your calculations. 3. It's not ideal for long-term storage at room temp — you'll want to keep it at -20°C in a dry enviornment, and we usually have stock, but confirm lead time on larger orders. 4. Most buyers go with the 10mg vials for their metabolic studies, but the 5mg size is easier to handle if you're running smaller assays. 5. We've seen it work better than first-generation GLP-1 analogs for prolonged activity, though it's really about teh half-life extension from the molecular modifications. 6. For ordering, the MOQ is 10 vials per size, we include a COA with each batch, and shiping is typically 20 days or so — just let us know quantity and we'll send a proforma invoice.
We can start with as low as 5 vials for the 15mg size, but larger orders get better pricing — just let us know your volume.
Yes, we include a COA with every batch, showing the ≥99% HPLC purity, peptide content, and moisture levels so you can verify specs.
Keep them at -20°C in a dry environment — no moisture exposure. Once opened, use the powder quickly and reseal tightly.
Sure, we can do custom vial sizes if you need a specific dose per vial, just tell us the quantity and we'll adjust.
Usually 5-7 business days for stock sizes, but if you need a rush we can sometimes ship in 3 days — just ask.
