We've got a batch incoming for a client running a 12-week metabolic study with 48 subjects, and they needed delivery within 10 days—cold chain shippng with dry ice and gel packs, plus we usually have stock on hand for orders under 500mg, but confirm lead time for anything larger.
It's a white to off-white powder, soluble in water, with a molecular weight of 4813.4 g/mol and purity at 99.9% by HPLC—basically tight enough for most in vivo work, though we don't have teh exact solubility limit in saline handy (usually 2-4 weeks for a custom COA if you need that).
Most buyers go with the 10mg or 50mg vials for reconstitution, and it's stored at -20°C protected from light—better than reagent grade for this applicaion, but it's definetly not suited for anything beyond research use, and the peptide chain is long enough that repeated freeze-thaw cycles degrade it noticeably after three cycles or so.
Also, the CAS is 2023788-19-2, and the molecular formula runs C225H348N48O68—just a heads-up that the powder can be hygroscopic, so open it in a dry environment or you'll get clumping.
Anyway, we're ordering 200mg total in 10mg vials, which covers the study and leaves a bit for pilot work—roughly 20 vials, each with a COA from the batch, and MOQ was fine at this quantiy.
We can start with as little as 1 gram for new clients, but bulk orders over 10 grams get better pricing. Just let us know your target quantity.
Yes, every batch comes with a COA showing ≥99.9% purity and HPLC test results. We can also share third-party lab reports upon request.
Store it at -20°C in a freezer, away from light. The vial is sealed under inert gas, but once opened, keep it dry and cold to prevent degradation.
Sure, we can repackage into smaller vials or add your own label for an extra fee. Just specify your requirements before shipment.
For in-stock items, we ship within 3–5 business days. Larger orders may take 7–10 days depending on batch testing and documentation.
