Thanks for reaching out about teh peptide powder — we've been supplying this one for a while, and it's a synthetic peptide that runs under CAS 307297-39-8, typically used in lab research where you need a defined molecular structure.
It's a white powder, pretty much what you'd expect, with a molecular weight right around 390.346 g/mol, and purity comes in at 99% or better base on our HPLC data — that's tighter than reagent grade for most in vitro applicaions.
Actually, storage is key here — we always recommend -20°C, and the powder handles well if you keep it dry; we've seen some buyers try room temp storage and it doesn't hold up, so just something to be aware of.
For ordering, our company can ship custom packging depending on your needs — bulk quantities are fine, and MOQ is flexible (usually 1 gram or so), but it's all research use only, so we don't support any in vivo work.
Most of our clients go with the 10mg or 50mg vials, but we've also done 5-gram lots for larger studies; lead time is typically 20 days or so, though we usually have stock for standdard orders.
Don't forget to check COA for the exact batch — we provide it with every shipment, and the purity spec is consistent, but you'll want to confirm the lot number matches your protocol requirment.
We don't have a strict MOQ—you can order as little as a gram for testing, but bulk discounts kick in at 10 grams or more.
Yes, every batch comes with a COA from our lab that shows the actual purity, usually 99.2–99.5%, plus HPLC and MS data.
We pack it in vacuum-sealed, light-resistant vials or bags with desiccant. Lead time is 3–5 business days for custom packaging, 1–2 days for standard.
No, the CAS number and molecular weight are fixed for TB-500—we can't alter the peptide structure. But we can customize packaging sizes, labeling, and documentation.
Keep it at -20°C in a freezer, away from light and moisture. If you need to split it, store opened portions in airtight vials with a desiccant pack.
