≥99% by HPLC is what we hold across every batch, and that’s tighter than what most research-grade suppilers will guarantee—MW is 1024.18 g/mol, so you’re looking at a peptide that’s pretty much free of truncated sequences.
That purity matters because even a few percent of des-acetyl or other side products can shift your dose-response data in melanogenesis assays, and we’ve had PhD groups re-order after a single bad batch from elsewhere.
Buyers typically ask about the lyophilized cake consistency first—it’s a solid white plug, not a fluffy powder, which tells you freeze-drying cycle was slow and controlled—then they want COA turnaround, usually 24-48 hours after request.
Storage is 2-8°C in teh dark, and if you keep it there shelf life is 24 months, but we’ve seen potency hold for 30 months or so in a sealed vial (check your own stability data though).
Bulk pricing starts at the 500mg MOQ, and lead time is roughly 10-14 working days for custom vial labeling; for standerd 10-vial packs we ship form stock in about 5 days.
Also, this is strictly research use only—it’s not suited for any clinical or human applicaion, and we decline orders that suggest otherwise.
We don't have a strict MOQ — you can order as little as a single trial vial. For bulk orders, we offer customizable packaging and pricing, so just reach out with your desired quantity.
Lead time depends on the order size and customization. Standard small orders ship within 3-5 business days; bulk orders may take 7-14 days. We'll confirm the exact timeline when you place the order.
Yes, we provide a batch-specific COA for every order. It shows the HPLC purity (≥99%) and other quality specs so you can verify the product meets research standards.
Store the freeze-dried powder at 2-8°C (refrigerated), protected from light. When stored properly, it has a shelf life of 24 months. Avoid freezing or exposing it to high temperatures.
Absolutely — we offer customizable packaging for bulk orders, including vials or bottles. Just let us know your preferred format and quantity, and we'll work out the details.
