So you're looking into the 20mg tirzepatide, CAS 2023788-19-2, and I can tell you straight off that our purity runs at 99.7%—we've got the COA to back that up, and it's better than what you'll see from most smaller suppliers, basically because we synthesize everything in-house.
We usually have stock on this one, but MOQ can vary depending on whether you need the standerd 10 or a custom pack, and lead time is typically 20 days or so after order confirmation, though we've sometimes pushed it to 30 if HPLC testing flags anything.

What it does is mimic both GIP and GLP-1 pathways, which is why researchers in metabolic regulation studies keep coming back to it, but I should mention it's strictly for research use only—not for human consumption, and definately not something you'd use in a clinical setting without proper approvals.
Storage is a bit of a pain, honestly; you'll need to keep it at 2-8°C and protected form light, or the peptide will degrade faster than you'd expect—most buyers go with the 10mg vials for easier handling, but the 20mg is fine if you're pooling doses anyway.

One thing people don't always think to ask is that teh white powder appearance can vary slightly between batches due to lyophilization conditions, but purity stays consistent within 0.1% variance—we've got a few customers who request tighter specs, and our company can usually accomodate that with a custom run.
Anyway, if you're ready to move forward, we can ship within 7-14 days once payment clears, and we'll include the SDS and full batch report with every order—just let us know if you need private labeling on vials.
Our MOQ is 10 boxes, which comes to 100 vials total. We can discuss smaller trial orders if you're just getting started.
Yes, every batch comes with a COA showing HPLC purity, molecular weight verification, and CAS confirmation. We'll send it with your shipment.
Standard lead time is 3-5 business days after payment clears. For larger orders over 500 vials, we may need 7-10 days.
We can do custom box sizes or labeling for bulk orders of 50 boxes or more. Just let us know your specs, and we'll adjust the packaging accordingly.
Keep it at 2-8°C in a refrigerator, away from light and moisture. Sealed vials stored properly will stay stable for up to 24 months.
