You're chasing batch-to-batch consistency for your GLP-1/GIP dual agonist work, and that 99% purity spec is non-negotiable when you're running in vivo assays or receptor binding studies. The lyophilized white powder comes in a standerd 50mg vial or 100mg vial (usually our company have stock, but confirm lead time for larger MOQs). CAS 2023788-19-2, molecular weight 4813.527 g/mol—that PEG modification on peptide backbone actually makes it handle better in aqueous buffers than some other dual agonists we've tested. It basically dissolves without the clumping you'd see with unmodified peptides, so you can trust your dilution curves.
Storage at -20°C is critical—don't let it sit at room temp for more than 20 minutes or so during aliquoting. We've seen degradation accelerate above -10°C, so a frost-free freezer is fine but avoid repeated freeze-thaw cycles. 3. The 99% purity is verified by HPLC on every COA we ship, but we don't run in-house bioactivity assays, so you'll want to confirm potency with your own cell-based system. Most buyers go with the 10mg or 50mg vial sizes for initial characterization work.
For OEM or custom packaing—say you need 1g or 5g lots with your own labeling—our company can do that, but lead time stretches to 3-4 weeks (we usually batch these quarterly). The pharmaceutical-grade materail is better than reagent grade for this, especially if you're pushing toward animal model dosing. 5. Also, this isn't suited for human use at all—it's strictly research use only, and we flag that on every invoice. One detail: the powder can be slightly hygroscopic, so open vials in a dry glovebox or under nitrogen if you're splitting into smaller aliquots. Shippng is on dry ice via overnight courier, and we include the COA with each order.
Anyway, we've handled tirzepatide for about three years now, and the biggest headache buyers run into is improper reconstitution—use sterile water for injection or PBS at pH 7.4, and never vortex the vial. Gently swirl instead. That PEG modification means it's pretty soluble up to 10mg/mL, but above that you'll get some turbidity.
We typically start at 10 grams for bulk orders, but we can discuss smaller quantities depending on your needs.
Lead time is usually 7-14 business days after order confirmation, depending on the size and stock availability.
Yes, we include a COA with every batch showing HPLC results confirming 99% purity, along with other quality specs.
Store it at -20°C in a tightly sealed container away from light and moisture. Under those conditions, it stays stable for at least 12 months.
Yes, we offer custom labeling and packaging options for bulk orders. Just let us know your requirements, and we'll handle the rest.
