We've got about 200 vials of the 10mg size ready to ship right now and the 5mg and 15mg usually need a few days lead time — cold chain shippng is included in the quote, just confirm the dry ice requirments with us.
The 99% purity isn't just a number on paper, it basically means fewer impurities to throw off your assays or cell work, we've had researchers tell us it's better than some reagent grade stuff form big lab suppliers.
4514.04 g/mol is molecular weight but what that really means is the peptide's pretty big, so reconstitution with sterile water or PBS takes a bit more solvent than smaller peptides (usually 2-4 weeks for full dissolution at 4°C).
White powder, store at -20°C, we ship in sealed foil bags with desiccant but don't leave it out at room temp for more than a few minutes or it'll clump.
Most buyers go with teh 5mg if they're running screening assays, the 10mg is the sweet spot for most in vivo work though — that's what we move the most of.
Actually, it's not great for oral dosing since the stomach chews it up, so stick to injection formulations or topical application if you're testing that angle.
For 5mg vials, MOQ is 10 units. If you need a custom quantity, just reach out and we can adjust for bulk research orders.
Yes, every batch comes with a COA showing HPLC results, confirming >99% purity. We can also share the mass spec data if needed.
It's sealed in a sterile, vacuum-packed glass vial with a rubber stopper. We ship with ice packs in an insulated box to maintain temperature during transit.
Yes, CAS 107761-42-2 corresponds to the full-length TB-500 peptide sequence. The molecular weight you see (4514.04 g/mol) matches that exact 43-amino-acid structure.
Absolutely. We can fill custom amounts from 2mg up to 50mg per vial. Just let us know the dosage and quantity, and we'll adjust the price accordingly.
Excellent delivery speed and packaging; the order arrived much faster than anticipated, which was a pleasant surprise. Everything was securely sealed, ensuring the product's integrity upon arrival. The customer service team was incredibly responsive and helpful, addressing my queries promptly and professionally. Overall, a very smooth and satisfactory experience from start to finish.
