You're looking at over 99.5% purity on this one, which is tighter than most research-grade peptides we see — that's the first thing buyers usually check. 2. What that means in practice is fewer impurities to complicate your results, especially if you're running or metabolic assays where consistency matters. 3. We keep it stored at 2-8°C in dry conditions, and I'd recommend you do the same form teh moment it arrives — it's a large molecule, 4813.5 g/mol, so stability is something to watch. 4. It's not ideal for anything beyond research use, just so we're clear — this isn't formulated for human or animal applicaion. 5. Most labs we supply go with the 10mg vials, but our company can do 2mg up to 50mg per vial, and we usually have stock in UK within 20 days or so (check lead time for larger orders). 6. And we'll send the COA with every batch, so you've got the HPLC data on purity right there.

We guarantee ≥99.5% purity by HPLC, and yes, we include a Certificate of Analysis with every batch.
MOQ is 10 vials (one box), and typical lead time is 3–5 business days after order confirmation.
We can adjust vial sizes within that range for bulk orders, but standard packaging is 2mg–50mg per vial, 10 vials per box.
It needs to be stored at 2–8°C in a dry place—refrigeration is required to maintain stability.
We supply a COA with purity results, HPLC chromatogram, and mass spec data upon request.
