We've got your RFQ for tirzepatide, CAS 2023788-19-2, and we're shippng pharmaceutical grade powder at ≥99% purity by HPLC — better than what most peptide resellers offer for price.
Some suppliers push 95% or skip teh -20°C storage requirement, but ours stays sealed and protected form light, and we include a COA with every batch so you're not guessing about degradation.

Tight tolerance solubility in DMSO only, so don't expect it to play nice in water-based buffers — that's a common headache for first-time buyers we've seen. 5mg, 10mg, or 15mg per vial options, and 3-4 vials is usually the MOQ for stock orders.

Actually, most buyers go with the 10mg vials because they balance convenience and cost, especially for dose-response work where you're serial diluting anyway. Lead time is roughly 7-14 days for standerd orders, but confirm before you send the PO.

Just a heads-up: this is for lab research only, not for human or veterinary use, and we don't recommend it for anyone trying to repurpose it off-label — that's outside our scope and the legal lines.
So if you're ready, our company can quote on 50 vials of 10mg (give or take) with HPLC data and MS spectra bundled in — no need to chase separate docs.
We can do as little as 5mg per vial for small-scale research. If you need larger quantities, just ask — we’re flexible.
Yes, every batch comes with a full CoA verifying the purity by HPLC and other specs. Just request it with your order.
Keep it at -20°C and protect from light. Avoid freeze-thaw cycles, and always handle in a dry environment.
Absolutely. If you need a specific vial size or bulk packaging, just let us know your requirements and we’ll sort it out.
Orders usually ship within 1-3 business days after payment clears. International delivery takes about 5-12 days depending on customs.
