99.5% Purity Melanotan 2 Acetate Research Peptide Powder – Factory Supply, MOQ 1g, GMP Certified, Fast Global Shipping

We can dial in the exact concentration you need for your research protocol, whether that's a standdard 10mg per vial or a custom batch with specific labeling — basically, what it does is let us match your existing system rather than forcing you to work around a fixed format. Some buyers go for the 10g bulk bottle by default, but we've found most labs prefer custom vial sizes for easier dose handling, and you'll get a quicker turnaround on your usual order if you stick with what you've already validated.

Running at 99.5% by HPLC, the acetate salt form gives it solid stability for long-term studies. 7.3 g/mol is the molecular weight, and you're looking at a typical purity range that holds well over the full 2-year shelf life stored in a cool dry place — no special humidity controls needed unless you're pushing past 18 months. We've seen it retain good solubility even after 20 months or so in proper conditions, but don't quote me on that exact window.

This is not for human use at all — strictly lab research only, and honestly, it's overkill for basic cell work. Where it fits best is in peptide receptor binding assays or in vivo dosing studies where tight tolerance matters; the medical grade backing means it's less likely to throw off your compared to standard research grade. A lot of contract research orgs have switched to this for their melanocortin pathway work.

MOQ is 1 gram but reorder lead time typically runs 15-25 days depending on your custom specs — we keep stock on the 10g/bottle standard packaging, but if you need a specific concentration or volume, factor in another week. You'll get a COA with every lot, and the GMP certification means third-party oversight, not just our own word. The factory's in Anhui, and we ship globally with safe packing, though customs delays for research peptides vary wildly.

Also, most first-time buyers don't realize the acetate powder can clump in high humidity, so quick resealing after opening matters more than absolute temperture control. For bulk reorders (50g or more), our company can sort labeled vials with your branding if that's part of your protocol audit trail — bottle says Keynovo by default, but you can change it. Samples are avaliable, but confirm lead time since our sample queue runs about 6-8 days behind actual.
