our company can actually do custom vial sizes and custom labeling if that's something you'd need for your research setup — a lot of buyers we work with come to us specifically because they're scaling up and standdard packs don't quite fit their dosing scheme, so we'll synthesize whatever bulk you're after, within reason.
The main specs you'll want to look at are a purity above 99.9% as verified by HPLC, the molecular weight runs 4113.6 g/mol, and it's a white powder that dissolves nicely in water though we usually recommend sterile water or saline for reconstitution.

What you get when ordering is each vial filled by fill weight so there's minimal variance — we're talking about 0.1 mg tolerance or so — and every batch ships with its own COA and a TDS if you need it; the storage conditions are pretty straightforward at 2-8°C in a dry spot, so it's not fussy.

It's not meant for anything beyond lab research obviously — we don't spin that as a positive or a negative, it's just a basic fact given the nature of peptide work and teh legal boundaries most research groups operate within.
Most buyers we deal with are in academic labs or smaller contract research orgs, and they typically go with the 10mg vials because of that it's a decent middle ground for a few dose-response studies before ordering a custom batch size; some of the biochemistry outfits actually prefer the 2mg vials for lower-concentration work.
We don't enforce a strict MOQ on the 2mg vials — you can order as few as 10 units to start. For larger quantities, just let us know and we can work out bulk pricing.
Yes, every batch comes with a COA that confirms the >99.9% purity and other specs like appearance and molecular weight. You'll get it with your order.
We can do custom labels for bulk orders — just specify your requirements. Standard packaging is the white powder in sealed vials stored at 2-8°C.
For a 500-vial order, expect around 7-10 business days for production plus shipping. We can expedite if needed, just reach out.
Keep it in a dry place at 2-8°C, away from light. The white powder is water-soluble, but avoid moisture until you're ready to reconstitute it for research use.
