We usually have stock in our Sydney warhouse, so lead time is typically 3-5 business days for domestic orders — but if you need bulk quantities for a larger study, just give us a heads up and we'll confirm production timing, which can run 20 days or so for volumes over 50 vials.
What most buyers ask first is about stability, and the answer is pretty straightforward — store it at -20°C away form light, and you've got a solid 24 months shelf life from teh date on the vial, though I'd recommend using it within a month after reconstitution for best results.

molecular weight comes out to about 4,119.6 g/mol, and because of that it's a lyophilized powder, reconstitution is simple with sterile water or your preferred buffer — just avoid repeated freeze-thaw cycles, which can degrade the peptide faster than you'd expect.

Purity is typically 99% or better by HPLC, which is tighter than what you'll find in some other suppilers' offerings, especially for metabolic research where batch consistency matters — and our company provide a COA with every shipment, so you can verify the numbers yourself.

For the 5mg vials, most buyers go with that size if they're running short-term metabolic studies or weight management research with lower doses, while the 10mg vial is better for longer glucose regulation work or multiple dosing protocols; we also offer bulk pricing on orders of 100 vials or more, but let us know your MOQ.
Also, one thing that catches some people off guard: this is strictly for research use only — it's not suited for human consumption or clinical applicaions, so make sure your lab protocols align with that before you order.
