Direct-Vision-Peptides High Purity Melanotan II (MT-2) 10mg for Research Use

We don't actually recommend this for long-term stability studies past a few months—the 10mg vial is really meant for short-term work where you reconstitute and use it within a week or so.

It's still go-to for most buyers running dose-response assays or binding studies because the ≥99% purity holds up under HPLC, and we've had consistent results batch to batch for about two years now.

The white powder comes in sealed vials with desiccant, and we usually stock 500+ units, but check lead time if you need custom labeling or concentration—that can add 2-3 weeks.

Storage is 2-8°C in a dry enviornment; we've seen folks try room temp and it degrades noticeably after 10 days. Basically, keep it cold.

Molecular weight is 1024.18 g/mol, and teh CAS is 121062-08-6, which matters for reconstitution calculations—most researchers go with bacteriostatic water at 1mL per vial.

Also, it's not suited for anything involving cell culture viability over 72 hours—the peptide's half-life in solution is roughly 4-6 hours at 37°C, so plan your timepoints accordingly.
