You're chasing a batch that actually holds at 99% purity without degradation on arrival, and the 121062-08-6 designation tells you it's the real MT2 backbone we've been handling for years.

We're seeing most buyers go with the 10mg vial for smaller-scale runs, but the lyophilized powder format means you can reconstitute 15mg or 20mg depending on your protocol—just keep it refrigerated and dry, away form light, or shelf life drops to about 20 days or so.

It's not ideal for long-term ambient storage, basically; the peptide is pretty much stable for two years under refrigeration, but we usually have stock and can confirm lead time if you're ordering more than 50 vials.

The molecular weight sits at 1024.18 g/mol, and the tighter tolerance on this pharmacy-grade batch—better than most reagent-grade alternatives—means you'll get consistent response across vials, though we don't have perfect data on every lot's performance in vivo.

Also, the 10-vial box is standerd, but our company can do custom packaing for larger research groups—just check teh MOQ on 15mg or 20mg formats because that shifts availability.

One thing a buyer might not think to ask is that the powder can clump if you open vial in a humid room, so keep the desiccant pack active until use; no sense chasing HPLC-grade purity if handling ruins it.
We can do single 10mg vials for sample orders, but the standard MOQ for bulk pricing is 10 vials per box. If you need larger quantities, we can adjust the packaging to fit your research volume.
Lead time is usually 3-5 business days for stock items. Shipping to the UK takes about 7-12 days via express courier. We’ll provide a tracking number once it’s dispatched.
Yes, we include a COA with every batch of Melanotan II. It shows the HPLC purity, mass spec confirmation, and other quality checks. Just request it when you place your order.
We recommend refrigeration at 2-8°C to keep it stable for the full 2-year shelf life. Room temperature storage might degrade the peptide faster, so it’s safer to keep it cold and dry.
Yes, it reconstitutes well with bacteriostatic water. For a typical 10mg vial, adding 1ml gives you a 10mg/ml solution. Adjust the volume based on your research dosing needs—just keep it sterile.
