You're setting up a study and need a consistent peptide source—we've seen labs burn through batches chasing purity specs that don't hold.
TB-500 at 99% (or 99.9% if you push for it) is what we run, in foil bags, 5mg or 10mg vials typically in stock.
What you'll get is a COA with each lot, HPLC-verified, and we don't round the numbers—if it's 98.7% we say so, though usually it's tighter than that.
It's not for in vivo work, obviously, but as a research intermediate it holds up better than reagent grade for binding assays or cell culture preps.
Store it cool and dark, avoid freeze-thaw cycles—one guy left a vial on bench for a week and teh activity dropped, so don't do that.
Lead time is usually 3-5 days for stock sizes, but confirm if you need a custom spec or larger MOQ.
We typically require a minimum order of 10 vials, but you can mix 5mg and 10mg sizes in that order. If you need a smaller quantity for initial testing, contact us and we can often work out a trial pack.
For in-stock TB-500, we usually ship within 3-5 business days after payment. If you need a custom label or bulk packaging, add about 5-7 more days.
Yes, every batch comes with a COA that includes HPLC purity results (99% min) and mass spec confirmation of the Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH sequence. We can share it before you order.
Keep the aluminum foil bag sealed in a cool, dry, dark place—ideally in a freezer at -20°C. Avoid repeated freeze-thaw cycles and minimize exposure to air or light once reconstituted.
Absolutely. We can print your own label or adjust the vial size and packaging material, as long as the order meets our minimum quantity. Just let us know your requirements.
