MT-2 (Melanotan 2) in brief
MT-2 (Melanotan 2) comes in one strength, 10mg x 10 vials, at $78.32 for the box of ten ($7.83 a vial, $0.783 per mg).
MT10 is not on the shelf today: it is made to order, about four weeks, in any quantity.
What MT-2 (Melanotan 2) is
Melanotan 2 is a cyclic heptapeptide analogue of the alpha-MSH core: Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, average mass 1024.2, in which the ring is closed by a lactam bond between the aspartate side chain and the lysine side chain rather than by a disulfide. It has a norleucine, a D-phenylalanine and an amidated C-terminus.
The lactam is stable, so the impurities are the tryptophan oxidation products under light and the open-chain precursor from synthesis, which weighs 18 units more. PT-141 differs from it only at the C-terminus, a free acid in place of the amide. The two differ by 0.984 in mass, amide against free acid, so their average masses sit within one unit; at high resolution their [M+H]+ ions are m/z 1024.548 for MT-2 and 1025.532 for PT-141. Telling MT-2 from PT-141, in a vial or in a mixture, takes a high-resolution mass, or HPLC run beside a reference of PT-141, and the certificate carries neither. It is stored dark.
Registry and identity
- With MT-II as its short form, Melanotan II is filed by FDA's GSRS as UNII UPF5CJ93X7 with CAS 121062-08-6 and PubChem CID 92432, its structure C50H69N15O9 with seven defined stereocentres. FDA GSRS
- In that structure the ring closes through an amide from the side chain of aspartate 2 to the side chain of lysine 7, the C-terminal lysine is an amide, the norleucine at 1 is N-acetylated, and phenylalanine 4 is the only D residue. FDA GSRS
- The acetate has its own entry, Melanotan II acetate (UNII WYE6CXB7CH, CAS 1036322-26-5, PubChem CID 91971817), drawn with one acetic acid at 1084.2, so acetate is 5.5 percent of that salt (worked from its formula). FDA GSRS, PubChem
- One name on that acetate record calls the ring a 2-7 disulfide, yet the record's own formula, C50H69N15O9 with acetic acid, contains no sulfur, so the ring can only be the side-chain amide. FDA GSRS
- Before the ring closes, the open-chain precursor is C50H71N15O10, one water more: worked from the two formulas with NIST isotope masses, its [M+H]+ is at m/z 1042.558 against 1024.548 for the cyclic peptide, and [M+2H]2+ 521.783 against 512.777. FDA GSRS, NIST
A listing in these registers identifies a substance; it is not an approval of this line.
MT-2 beside PT-141 and MT-1
Its neighbours, on price alone: PT-141 at $0.740 per mg at 10mg (P41), 1,025.2 g/mol, set side by side in MT-2 vs PT-141; MT-1 at $0.742 per mg at 10mg (MT110), 1,646.9 g/mol, set side by side in MT-1 vs MT-2.
Reading an MT-2 (Melanotan 2) certificate of analysis (COA)
Identity by mass. Average mass 1024.2 (C50H69N15O9). In electrospray the protonated ions come near m/z 1025.2 (singly charged), m/z 513.1 (doubly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit; PT-141, at 1025.2, sits within one unit of it; at high resolution their [M+H]+ ions are m/z 1024.548 for MT-2 and 1025.532 for PT-141.
- Oxidation: 1 tryptophan, which oxidises to kynurenine and hydroxy forms under light. Kynurenine makes the chain 4 heavier and a hydroxy tryptophan 16.
- Deamidation: no asparagine or glutamine, but the C-terminal amide can hydrolyse to the free acid, which is PT-141’s structure, 0.984 heavier, inside the tolerance of the average-mass line; telling the acid from the amide takes a high-resolution mass, which the certificate does not carry.
- N-terminus: capped with an acetyl group, so there is no free N-terminal amine.
- Charge: near neutral pH about +1, basic.

Questions about MT-2 (Melanotan 2)
Which part of MT-1 does MT-2 keep?
The middle of the chain. MT-1’s residues 4 to 11, Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys, become MT-2’s Nle-Asp-His-D-Phe-Arg-Trp-Lys: the glutamate is replaced by an aspartate, the glycine is dropped, and the new aspartate is bonded through its side chain to the lysine’s, which closes the lactam ring. MT-1’s first three residues, Ser-Tyr-Ser, and its last two, Pro-Val, are gone, which takes thirteen residues to seven and 1,646.9 to 1,024.2; both keep the acetyl cap at the start and the amide at the end.
How much does MT-2 (Melanotan 2) cost?
It is $78.32 a sealed box of 10 vials, which works out at $0.783 per mg. To a US address, freight is included from $1,000 of goods; below that it is the carrier’s rate for the carton or a flat $35.00, and to another country the desk quotes it; either way the figure is on the proforma before you pay. The price per vial is in this page’s price table.
What does MT-2 (Melanotan 2) cost per mg?
It is offered in one size, MT10 at 10mg x 10 vials, which works out at $0.783 per mg at $78.32 a sealed box of 10 vials. Freight included to US addresses from $1,000 of goods.
Can I buy a single vial of MT-2 (Melanotan 2)?
No. One sealed box of ten vials is the smallest quantity of a regular line; for MT-2 (Melanotan 2) that is MT10, 10mg x 10 vials, at $78.32. A first order must reach $100 of goods, so MT10 alone takes two boxes ($156.64) or one box beside other lines. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Is MT-2 (Melanotan 2) in stock today?
No. MT10 is made to order, about four weeks, in any quantity.
How is MT-2 (Melanotan 2) stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of MT-2 (Melanotan 2)?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. MT-2 (Melanotan 2) is supplied as a powder in a sealed glass vial and in no other presentation. Its specification sheet carries the catalogue name, MT-2 (Melanotan 2 Acetate). Boxes are not split.
Is a certificate of analysis (COA) provided for MT-2 (Melanotan 2)?
Yes. For MT-2 (Melanotan 2) the batch certificate reports its purity, net content and identity by mass spectrometry. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
