The 99% purity on this batch is confirmed by HPLC, and we actually ran it through a second round of testing to be sure. We've seen some supliers claim that number and ship stuff at 96% or so, which makes a difference when you're titrating doses in a study that lasts months.
You'll get a white powder—off-white if it's been sitting a bit—in sealed vials with desiccant, and we usually have stock for the 1 gram MOQ, but confirm lead time if you need more than 50 units. Just keep it at 2-8°C and dry, it's stable for about 24 months that way, though some researchers push it to 30.
Most buyers go with the 1 gram sample first to run a quick solubility test in water, and what it does is dissolve cleanly with no particulates. The 1024.2 g/mol molecular weight is standerd, but we pack it with a tight tolerance on vial fills (usually within 5mg), so your reconstitution calculations don't wander.
One thing to watch—this isn't great for any in vivo work with long-term storage at room temp, the peptide degrades noticeably. We've had a few clients try to stretch it, and the loss in activity is pretty clear by month six. Anyway, for research use only, it's a solid tool for melanogenesis or feeding behavior studies, and we include sequence (the Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2) on the COA form GMP-certified production.
Standard orders ship within 1-3 business days after payment confirmation. If you need faster delivery, just let us know and we can arrange expedited shipping at cost.
Yes, we include a CoA with every shipment showing 99% purity verified by HPLC. You can also request the full batch analysis report before ordering.
Keep it refrigerated at 2-8°C in a dry place away from light. The sealed vial with desiccant is designed for that, so don't open it until you're ready to reconstitute.
Absolutely, samples are available. You just pay the shipping cost, and we'll send a small quantity so you can test purity and solubility in your lab.
Yes, it's soluble in water. Just add sterile water or bacteriostatic water and swirl gently—no need to heat or shake vigorously.
