What really makes it worth buying is the consistency batch to batch—we’ve been sourcing form this suppiler for about a year now, and every single vial we’ve tested comes back at 99% or better on HPLC, which basically means you can trust the data you’re generating without second-guessing matrial.
The molecular weight sits at 889.02 g/mol with that C38H68N10O14 formula, and it’s a that reconstitutes cleanly (usually takes 30 seconds or so with bacteriostatic water). Most buyers go with the 10mg vials because they’re easier to split across a study, but the 5mg works fine if you’re running smaller assays.
Storage is pretty straightforward—keep it in a cool, dry place and you’ll get the full 2-year shelf life, though we usually have stock ready to ship within 20 days or so. One thing nobody tells you is that the powder can clump slightly if exposed to humidity, so open the vial in low-moisture enviornment.
It’s not great for long-term stability testing at room temp; you really need to freeze it if you’re not using it within a month. But for typical research protocols, the pharmaceutical grade holds up better than reagent grade for this peptide—tighter tolerance on the purity spec.
Packaing comes as 10 in either 5mg, 10mg, or 20mg formats, and we’ve never had a vial arrive cracked or with a bad seal. Actually, the supplier includes a COA with every batch, which saves us the headache of running our own HPLC every time.
Anyway, for the price point and the consistency, it’s a solid choice for most labs—just confirm lead time if you need more than 50 units or so, because they sometimes run a bit behind on larger orders.
Our TB-500 is ≥99% pure, tested by HPLC to confirm that level. We include a certificate of analysis with each batch.
The standard MOQ is 10 vials per box, available in 5mg, 10mg, or 20mg sizes. You can mix sizes in one box if needed.
Yes, we supply a COA for every batch, covering purity and identity. Third-party lab reports are available on request.
Keep it in a cool, dry place away from direct sunlight, ideally at 2-8°C. Once reconstituted, use within a few days and refrigerate.
We can adjust vial sizes or box quantities for bulk orders, just let us know your needs. Minimums may apply for custom packaging.
