99% purity is what we consistently see on every COA, and for a peptide of this molecular weight—4813 g/mol—that’s tighter than most bulk intermediates we’ve sourced.
We store it at -20°C for long-term, but if you’re working through a batch in 2-4 weeks, 0-4°C in a dry, dark drawer works fine—just don’t let it sit out.
Basically, the lyophilized powder reconstitutes cleanly, though we’ve found the 10mg vial size is easier to handle for smaller-scale work than the 30mg ones.
Also, the CAS is 2023788-19-2—you’ll see it on the label—and the EC number 200-001-8 is there for customs, but we usually have stock ready, so lead time is about 20 days or so.
One thing a new buyer might not think to ask: teh vial stoppers are single-use, so if you’re planning multiple draws, order extra vials—we’ve had to learn that hard way.
It’s not for anything beyond research use, obviously, and we don’t push it for personal consumption—anyway, the 5mg vials are better for titration experiments, but the 15mg ones save on vial changes.
We typically require a minimum order of 10 vials per box, but for larger bulk orders, we can discuss lower per-vial pricing. Just reach out with your desired quantity.
Standard lead time is 3–5 business days after order confirmation for in-stock items. For larger bulk orders, it might take 7–10 days depending on your location.
Yes, we supply a COA with every batch that verifies the 99% purity and other specs like molecular weight and appearance. You can request it before or after purchase.
We generally stick to the standard vial sizes listed, but for large bulk orders, we may be able to customize the fill amount per vial. Contact us to discuss your needs.
Store it in a dry, dark place at 0–4°C for short-term use, or at -20°C for long-term storage. Avoid moisture and light to keep it stable for over 2 years.
