Melanotan 2 peptide is a synthetic analog of alpha-melanocyte-stimulating hormone that researchers study in melanocortin and pigment research. Simple Peptide sells it as a US manufactured research peptide with a third-party COA for every batch. Start with our Melanotan II research vial.

Melanotan 2

Melanotan 2 is a cyclic seven-amino-acid peptide based on alpha-MSH, the hormone that signals melanocortin receptors. Researchers study it because it binds several of these receptors. That makes it a useful tool in receptor and pigment research.

Picture a research buyer comparing Melanotan 2 listings late on a Friday. One shop shows no lot number. Meanwhile, another shows a blurry certificate. Instead, our Melanotan 2 peptide listing links straight to the batch report on our COA page. So the buyer can confirm the batch, place the order and close the laptop.

MT-2

MT-2 is the short code for Melanotan 2 peptide, and many buyers type it as MT 2 peptide in search. In fact, both forms name the same synthetic melanocortin agonist that researchers study in melanogenesis work.

Short codes are handy, but they can also confuse an order sheet. For example, a lab may list MT-2, MT-II and Melanotan II as three separate items. Therefore, we use one clear product name and one lot number per vial. That keeps your records tidy from order to bench.

MT-II Peptide

MT-II peptide is the Roman-numeral spelling of Melanotan 2 peptide, common in older papers and supplier catalogs. However, the compound and its research use stay the same, whichever spelling you search. You can explore the literature through a PubMed search for Melanotan II.

Many researchers start with the published papers, then look for a matching supplier. When they search MT-II peptide, they want the same compound those papers describe. Our Melanotan II vial uses the standard name, and every batch comes with a COA. So the match between paper and product stays clear.

Melanotan

Melanotan is the shared name for two synthetic alpha-MSH analogs, Melanotan 1 (MT1) and Melanotan 2 (MT2). MT1, also called afamelanotide, is a linear peptide that favors the MC1 receptor. In contrast, MT2 is a smaller cyclic peptide that binds several melanocortin receptors.

Because the two compounds differ in structure and receptor profile, labs often keep both on hand for comparison work. In that case, ordering both from one store keeps the paperwork simple. We stock Melanotan 1 10MG alongside Melanotan II, and each batch has its own COA.

Melanotan Peptide

Melanotan peptide is the broad search term buyers use before they pick MT1 or MT2. It also covers the whole melanotan family of research peptides. So the first step is to match the compound to your study design.

Imagine a new lab assistant who gets a request for “melanotan peptide” with no other detail. First, they check the study notes for MT1 or MT2. Next, they compare formats, such as a powder vial or a dissolving strip. Finally, they browse our melanotan category and order the matching item with its COA.

Tanning Peptide

Tanning peptide is the informal nickname that researchers and buyers use for melanotan compounds. The name comes from the research area, because scientists study these peptides in melanogenesis, the process cells use to make melanin pigment.

The nickname describes a research topic, not an outcome, and we use it that way. Our listings stay strictly technical: compound name, format, lot number and COA. So if you searched tanning peptide, start with a Melanotan 2 peptide vial or the Melts Pro strips below. Both carry batch testing records, and both serve lab research only.

MT1 Peptide

MT1 peptide is the short name for Melanotan 1, a linear 13-amino-acid alpha-MSH analog that the literature also calls afamelanotide. Researchers also study it for its selective binding at the MC1 receptor.

Some studies need the more selective compound rather than MT2. In that case, our Melanotan 1 10MG vial gives your lab a single, clearly labeled option. Check the matching COA, then add it to your order alongside any MT2 vials.

Buy Melanotan 2 Peptide With a COA

Buying Melanotan 2 peptide should feel simple. First, we list one product name, one lot number and one COA per batch. In addition, you can choose between the classic powder vial and the Melts Pro Melanotan II dissolving strips. Have a question about an order? Our team answers it through the contact page.

Frequently asked questions

Is MT-2 the same as Melanotan 2 peptide?

Yes. MT-2, MT 2 peptide, MT-II and Melanotan II all name the same synthetic cyclic peptide.

What is the difference between MT1 and MT2?

MT1 is a linear peptide that favors the MC1 receptor. MT2, however, is a smaller cyclic peptide that binds several melanocortin receptors.

Why do people call it a tanning peptide?

The nickname comes from melanogenesis research, the field where scientists study these compounds. It describes a research area, not a promised effect.

Do you publish test results?

Yes. We post a certificate of analysis for every batch on our COA page, so you can check a lot before you order.
