MT-2 (Melanotan 2 Acetate): price, documentation and dispatch in Colombia
MT-2 (Melanotan 2 Acetate) is offered at Peptidos Colombia as a research and laboratory-work reference. Technically, it is a cyclic seven-amino-acid analog of the alpha-MSH hormone, and it shares that technical category with only two other catalog references: MT-1, of linear structure, and PT-141, also cyclic. Its presentation is 10 mg in lyophilized powder, with catalog code ML10. Lot identity and purity are confirmed by the certificate of analysis issued by Janoshik Analytical, per lot, with HPLC for purity and mass spectrometry for identity, upon institutional request and subject to the lot's documentary availability. This listing brings together classification, presentation, documentation, and logistics without proposing any use outside the declared research framework.

MT-2: the cyclic seven-amino-acid analog of alpha-MSH
MT-2's classification as a cyclic seven-amino-acid analog of the alpha-MSH hormone describes its structural architecture: a short chain closed on itself, distinct from a linear peptide of the same length. This description comes from the catalog's technical listing and does not anticipate any analytical data for a specific lot.
The full name, MT-2 (Melanotan 2 Acetate), includes the acetate salt and should be recorded the same way in any institutional request, to distinguish it from MT-1 and PT-141, the other two references in the same melanocortin-analog technical category.
Three references, two architectures: linear versus cyclic
The catalog's melanocortin-analog category gathers only three references: MT-1, a linear 13-amino-acid analog; MT-2, a cyclic seven-amino-acid analog; and PT-141, also a cyclic seven-amino-acid analog, though derived from separate development. Two of the three share cyclic architecture and chain length; one differs by being linear and longer.
This grouping by structural architecture, not by commercial name, is what allows comparing the three references verifiably: sequence length and cyclic or linear form are catalog data, not value judgments about any consequence. For an institutional request needing all three references in this category, it is worth checking each full name, including the declared salt, before confirming the quote. Each one's catalog code — for example ML10 for MT-2's 10 mg presentation — is additional data that can be cited alongside the name to reduce any ambiguity when an order combines more than one of the three.
MT-2, PT-141, and MT-1: what to declare in each quote
Each of the three melanocortin-analog references — MT-1, MT-2, and PT-141 — has its own price, shown in its own listing's commercial block, which is worth checking separately before approving any quote.
Two references sharing a category does not mean their lot certificates are interchangeable: each keeps its own COA, requested and verified separately.
10 mg presentation and its physical form as lyophilized powder
MT-2's 10 mg presentation is declared by mass, corresponding to a lyophilized powder in a vial under the catalog's criterion. It is the only presentation currently active for this reference, as is also the case for MT-1 and PT-141 within the same three-member category.
The receiving laboratory sets its own protocol for subsequent handling of the lyophilized powder; this listing does not replace it. What can be planned from the catalog is the custody space based on the declared storage condition.
COA per lot: Janoshik Analytical, HPLC, and mass spectrometry
MT-2's certificate of analysis is issued by Janoshik Analytical, per lot, with HPLC for purity and mass spectrometry for identity. For a cyclic analog like this one, that second technique is what distinguishes the closed ring form from a linear version of the same sequence, a mass difference the lot document can confirm. Given that this is a category with only three structurally related references, confirming that the received COA corresponds exactly to MT-2 and not to MT-1 or PT-141 is a particularly relevant verification step.
This listing does not publish a purity figure for MT-2 until a COA has been requested and reviewed for the specific lot. CAS number, molecular formula, and molecular weight remain visibly pending, the same as for other references without specific documentary support.
Domestic shipping, payment, and filing the quote
Shipping rates to Bogotá and to other destinations within the country are on the site's shipping information page, confirmed at the time of the quote. The declared storage condition, currently 2–8 °C, protected from light, should be ready before delivery. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
The order is logged, confirmed in writing in the institutional quote, and only afterward is payment coordinated. The final file brings together the request, the quote, proof of payment, shipping, receipt, and the lot's COA when requested.
Frequently asked questions about MT-2 (Melanotan 2 Acetate)
What is MT-2 (Melanotan 2 Acetate)?
A cyclic seven-amino-acid analog of the alpha-MSH hormone. It is offered exclusively for research and laboratory work.
How does MT-2 differ from MT-1?
MT-1 is a linear 13-amino-acid analog; MT-2 is cyclic and seven amino acids long. They are separate references within the same melanocortin-analog category.
Are MT-2 and PT-141 the same reference?
No. Both are cyclic seven-amino-acid analogs derived from alpha-MSH, but they are separate references, each with its own code, presentation, and lot certificate.
Who certifies the lot's identity and purity?
Janoshik Analytical, per lot, with HPLC for purity and mass spectrometry for identity, upon institutional request and subject to the lot's documentary availability.
How is this reference stored?
According to the documentation applicable to the lot, currently in a range of 2–8 °C, protected from light.
What catalog code does this presentation have?
ML10, associated with the 10 mg presentation. Useful for distinguishing MT-2 from MT-1 and PT-141 in a quote covering several references from the same category.
