So you're looking at TB-500 for your research program—we've been moving a fair amount of this peptide to labs in the US and EU recently, and import docs are straightforward for these regions since it's research-use only, typically just a TDS and SDS with the shipment.
Most buyers go with the 10mg or 20mg vial for angiogenesis studies, though we see some picking the 5mg for smaller pilot runs, and it basically holds up well under standerd lab handling if you reconstitute it properly.
Purity runs >99% by HPLC, which we verify per batch, and teh molecular weight is around 890 g/mol—that tight tolerance is better than reagent grade for this kind of work since you're looking at anti-inflammatory pathways where even trace impurities can mess with your data.
We don't always have every size in stock at once (the 50mg tends to move fast, so confirm lead time if you need that), but we ship form regional hubs so you'll typically see dilevery in 20 days or so to the UK or EU.
One thing buyers don't always think about is that the powder is hygroscopic, so you'll want to bring the vial to room temperture before opening—we've had a few inquiries about clumping after improper storage at 0-4°C, and honestly it's just a fact you need to plan for.
CAS 885340-08-9 is what we reference on the COA, and our company can include the HPLC chromatogram if your compliance team asks—no extra charge for that, though the MOQ on custom blends is usually 50 units or so for us to run a dedicated production batch.
We don't have a strict MOQ — you can order as little as a single 5mg vial if you want. Bulk discounts kick in at higher quantities.
Yes, every batch comes with a CoA showing HPLC results verifying the purity exceeds 99%. Just ask when placing your order.
For long-term storage, keep it at -20°C in a sealed, moisture-free container. Short-term, 0-4°C works fine for a few weeks.
The 50mg option is a single vial. All our packaging sizes — 5mg, 10mg, 15mg, 20mg, 30mg, and 50mg — are individual vials.
Sure — we can supply a batch-specific certificate of analysis and a pharmaceutical grade statement upon request. Just let us know.
