MT-1: price, documentation and dispatch in Colombia
MT-1 is offered in a single presentation, 10 mg vial, from US$94, classified as a linear 13-amino-acid analog of the alpha-MSH hormone. Although its commercial category is "Other catalog compounds," its structural classification groups it with two other site references — MT-2 (Melanotan 2 Acetate) and PT-141 — within the melanocortin analog family. The key word that sets MT-1 apart from those two related references is linear: unlike them, it does not form a ring. This page documents that structural distinction, the current presentation and price, and the per-lot certification process through Janoshik Analytical, strictly within the framework of research and laboratory work.

Linear, not cyclic: the structural distinction that defines MT-1
The published classification describes MT-1 as a linear 13-amino-acid analog of the alpha-MSH hormone. Linear is the word that sets it apart from its two closest relatives in the catalog: MT-2 (Melanotan 2 Acetate), described as a cyclic seven-amino-acid analog, and PT-141, described as a cyclic heptapeptide melanocortin analog. All three derive from the same reference hormone, but MT-1 does not form a ring and has a longer chain.
That difference — an open 13-amino-acid chain versus cyclic 7-amino-acid structures — is a structural classification fact documented in the catalog, not a hierarchy of any kind among the three references. Each keeps its own code, presentation, and price.
A single presentation, under a commercial category that does not reflect its family
The catalog offers MT-1 in a single presentation, 10 mg vial, with a current listed price from US$94. The commercial category it appears under — "Other catalog compounds" — is the same generic label that groups several references with no assigned thematic classification in the original commercial field, even though their structural classification is documented as a melanocortin analog.
That mismatch between commercial category and structural family is not unique to MT-1: Cardiogen, also part of this catalog, shows the same situation with the short peptide bioregulator family. This page describes MT-1 by its real structural classification, without promising a change of commercial category that this content does not control.
Certificate of analysis per lot: Janoshik Analytical, HPLC, and MS
MT-1's identity as a linear 13-amino-acid analog does not replace the documentary verification of each specific lot. That verification is the role of the certificate of analysis (COA) that Janoshik Analytical issues per lot: high-performance liquid chromatography (HPLC) for purity and mass spectrometry (MS) for identity.
The COA is handled on request and subject to documentary availability. This page does not publish a purity figure for MT-1, nor a CAS number, nor a molecular weight: if those data are not in the delivered lot's document, they remain pending, not filled in by comparison with MT-2 or with PT-141.
Physical form and storage of the 10 mg vial
The 10 mg MT-1 vial corresponds to a powder presentation, the same physical form as its two cyclic relatives in the catalog, MT-2 and PT-141, both also presented in 10 mg vials according to their own pages. The site's technical sheet states storage at 2–8 °C, protected from light, for this type of reference.
That storage condition should be confirmed against the specific documentation of the MT-1 lot received. On arrival of the order, the full reference name — MT-1, not to be confused with MT-2 — and the lot visible on the vial should be checked against the accepted quote.
From quote to payment for MT-1
Selecting MT-1 in the catalog does not generate an immediate charge. The request is recorded first with the 10 mg presentation and the current price; the commercial confirmation that follows fixes the total, the destination, and the payment method in writing. Shipping is calculated separately, with rates for Bogotá and for the rest of the country shown on the site's shipping information. 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.
Since MT-1 and MT-2 (Melanotan 2 Acetate) share a catalog and a nomenclature that is easy to confuse in writing, it is worth having the institutional request spell out the full name of the desired reference and confirm it in the quote before approving payment.
MT-1 versus MT-2 (Melanotan 2 Acetate): linear against cyclic
The most direct comparison within the catalog is between MT-1 and MT-2 (Melanotan 2 Acetate): both derive from the alpha-MSH hormone, but MT-1 is a linear 13-amino-acid analog and MT-2 is a cyclic seven-amino-acid analog. The difference in structure — linear versus cyclic — and in chain length are classification facts, not a comparison of outcomes.
PT-141, the third reference in this same family in the general catalog, adds a third variant: a cyclic heptapeptide, cyclic like MT-2, but with its own sequence. All three keep their own code, presentation, and price in the catalog, and this page limits itself to documenting these structural differences.
Frequently asked questions about MT-1
What presentation and price does MT-1 have?
10 mg vial, with a current listed price from US$94. It is the only presentation registered for this reference.
How is MT-1 different from MT-2 (Melanotan 2 Acetate)?
MT-1 is a linear 13-amino-acid analog of the alpha-MSH hormone; MT-2 is a cyclic seven-amino-acid analog of the same hormone. The difference is one of structure (linear versus cyclic) and chain length.
Why does MT-1 appear under "Other catalog compounds"?
It is the commercial category inherited from the original source field. Its real structural classification places it alongside MT-2 and PT-141 in the melanocortin analog family, even though the commercial label does not reflect that.
How is the identity of an MT-1 lot confirmed?
With the certificate of analysis (COA) from Janoshik Analytical: HPLC for purity, mass spectrometry for identity, per lot, on request and subject to documentary availability.
How much does shipping cost for an order with MT-1?
Rates for Bogotá and for the rest of the country are shown on the site's shipping information, with delivery time confirmed in the institutional quote. 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.
