Best Place to Buy Melanotan 2 in 2026

Short answer: Amino Club (Bureau Score 4.8), the Bureau's first choice for Melanotan 2. Below is why, the three alternatives worth knowing, and what to check before any order. Melanotan 2 is sold by these stores for laboratory research use only, not for human use. It is also spelled Melanotan II, and stores list it under either name.

What to know before buying Melanotan 2

Melanotan 2 (MT-II) is a synthetic cyclic seven residue analogue of alpha-melanocyte stimulating hormone, Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2. It is studied for its effects on skin pigmentation and on melanocortin receptors, including sexual function.

Melanotan 2 is not approved by the FDA, and the UK medicines regulator said in 2009 that it is unlicensed and that any supply or advertising of it is illegal. FDA's compounding safety page (current as of 22 April 2026) lists it among peptides once placed in category 2 and later withdrawn by their nominators, citing published case reports of serious adverse events including melanoma, posterior reversible encephalopathy syndrome, sympathomimetic toxidrome and priapism.

• What to match on the certificate: Match the identity line to C50H69N15O9, average molecular weight 1024.2 (monoisotopic 1023.54). Bremelanotide (PT-141) has the same ring but ends in a free acid instead of an amide (C50H68N14O10, 1025.2), only about 1 apart, so the mass spec result has to be read closely, alongside HPLC purity on the same lot number as the vial.
• Vial sizes: Research stores sell it almost only as 10 mg vials; check the label says Melanotan II or MT-II, since Melanotan 1 (afamelanotide) and PT-141 (bremelanotide) are different compounds.
• What it costs: 7 stores the Bureau reviews list Melanotan 2; on 1 November 2026 the in-stock list prices ran from $2.35 per mg (Sports Technology Labs, 10 mg vial) to $6.90 per mg (Direct Peptides, 10 mg vial), before any code.
• Storage: Cayman Chemical states Melanotan II as supplied is stored at -20 C with a stability of at least 4 years; once reconstituted, suppliers generally say a peptide should be refrigerated and used within a short window, or split into aliquots and frozen, avoiding repeated freeze and thaw.

How the Bureau picks

The pick is the vendor at the top of the Bureau's vendor list that stocks Melanotan 2. Scores come from the scorecard, which weighs lab documentation, consistency, shipping and price, and a vendor cannot buy a score. Before any order, match the lot number on the vial to a certificate from a named third-party lab. More in the vendor scorecard and the Melanotan 2 guide.

Frequently asked questions

Where is the best place to buy Melanotan 2?

The Bureau pick is Amino Club (Bureau Score 4.8). Batch COA on every product page from an 8-assay panel at an ISO 17025 lab. Alternatives that stock it: Ascension Peptides, NextgenPeps, Aurelia Research.

Is there a discount code for Melanotan 2?

How do I check a Melanotan 2 vendor before ordering?

Match the batch or lot number on the vial to a certificate from a named third-party lab, check the test date, and look for identity (mass spec) as well as purity (HPLC). The Bureau's scorecard records which vendors do this.

What is the difference between Melanotan 2 and PT-141?

They share the same seven residue ring, but Melanotan 2 ends in an amide and PT-141 (bremelanotide) in a free acid. Bremelanotide was approved by the FDA on 21 June 2019 as Vyleesi for premenopausal women with hypoactive sexual desire disorder; Melanotan 2 is not approved.

Is Melanotan 2 the same as Melanotan 1?

No. Melanotan 1 is afamelanotide, a longer peptide (molecular weight 1646.8 against 1024.2), approved by the FDA in October 2019 as the Scenesse implant for adults with erythropoietic protoporphyria. Melanotan 2 is a different, unapproved compound.
