Comes in 5mg, 10mg, or 20mg vials as a that reconstitutes clean in water—we usually stock all three sizes, but the 10mg is what most buyers go with for standerd dosing. Basically, it’s synthetic version of thymosin beta-4's active fragment, so researchers use it for tissue repair and inflammation models. Its molecular weight is 889.02 g/mol, and we sell it strictly for research use only, not for any human or veterinary application.
A lot of our customers are running angiogenesis or stem cell studies, and they’ve found it works better than some crude preparations for promoting capillary formation. It’s not great for anything involving high-throughput screening where solubility in organic solvents is required—water solubility is fine for most buffers, but don’t expect it to dissolve in ethanol. The CAS number is 885340-08-9, and the formula C38H68N10O14 is what you’ll see on the COA.
We test every batch by HPLC, and purity is always 99% or better—you get a copy of the COA with each shipment, which also includes the residual solvent data and appearance check. We’ve been handling this peptide for a few years now, and I’d say the batch-to-batch consistency is tighter than some other suppilers we’ve tested against. That said, storage is critical: 2-8°C, protected from light, or the shelf life drops—we state 24 months, but we’ve seen degradation after 18 months in less-than-ideal conditions.
Orders over 50mg typically get a discount, but our MOQ for custom sizes is usually 20mg or so. Payment is via T/T or wire transfer, and we ship from our facility within 3-5 business days after payment clears (confirm lead time for larger quantities). We’ll include an MSDS and packing list with every order, and if you need a specific packaging format, we can do individual vials or bulk bags—just specify at checkout
Also, if you’re ordering for the first time, we require a brief research statement to comply with end-use restrictions—it’s a formality, but our company can’t ship without it. The pricing per mg drops significantly at 100mg quantities, though we don’t always list that on the site.: international shippng can take 7-14 days, give or take, and customs clearance is your responsibility—we label everything as “research chemicals” with the CAS number on the box.
We stock 5mg, 10mg, and 20mg vials, but we can also make custom sizes if you need something different — just let us know the quantity.
Yes, every batch ships with a Certificate of Analysis showing ≥99% purity by HPLC, so you can verify the quality yourself.
For standard sizes, we usually ship within 3-5 business days. Larger wholesale orders may take 7-10 days depending on volume.
Keep it at 2-8°C in a fridge, away from light. Make sure the vial stays sealed until use, and avoid moisture.
We don't have a strict MOQ — you can order as little as 5mg. For wholesale pricing, we typically recommend at least 50mg per order.
