We’ve been handling this TB-500 and GHK-Cu blend for a while now, and it’s pretty much a staple in wound healing and angiogenesis studies—the 10mg and 50mg per vial ratio is what most labs request for co-administration protocols, though you’ll want to reconstitute seprately before combining them in the buffer.
The 99% purity holds up under HPLC, and we typically see batch-to-batch variation of less than 0.3% if you’re running your own verification—just don’t expect it to dissolve instantly in saline at room temperature, it needs gentle swirling for about 2 minutes or so to go fully clear.
Storage is critical here; we keep it at -20°C for long-term stability, but if you’re going through a vial in a week, 4°C works fine as long as it’s in a dark, desiccated container—the lyophilized cake is hygroscopic, so any moisture exposure (even form opening vial in high humidity) will degrade it noticeably.
What it does is it targets thymosin beta-4 pathways for cell migration and GHK-Cu’s copper-dependent matrix remodeling, but it’s not suited for acute inflammation models where you need a pure anti-inflammatory—the copper ion can actually amplify oxidative stress in some cell lines.
Most buyers go with the 10-vial box (that’s the standard MOQ), and we always include the COA with each shipment, though we usually have stock to ship within 3 business days—confirm lead time if you need more than 50 boxes at once.
One thing you might not think to ask: teh vial stopper is butyl rubber, not silicone, so if you’re using DMSO as a solvent, it will swell the septum after a few punctures—we’d recommend a single-use reconstitution approach if you’re working with organic solvents.
Our standard MOQ is 10 vials, which comes as one box. If you need smaller quantities, just let us know—we might be able to work something out depending on stock.
Yes, we can supply a COA with every batch. Just request it when you place your order, and we'll send it along with the shipment.
For short-term storage, keep it in a dry, dark place at 0-4°C. If you're holding it for longer, pop it in the freezer at -20°C to keep it stable.
We can do custom packaging for larger orders, like adjusting vial count per box or adding your label. Minimum for customization is usually a few hundred boxes—just chat with us about your needs.
Lead time is usually 7-10 business days for standard orders. If you need it faster, rush shipping is available at an extra cost—just let us know upfront.
