Melatonin: price, documentation and dispatch in Colombia
Melatonin is offered at Péptidos Colombia as a laboratory reference for research, within the catalog's classic hormones and cofactors category. Technically it is an indolamine — N-acetyl-5-methoxytryptamine — and not a peptide, a classification it shares, each in its own way, with Alprostadil and Vitamin B12 within the same group. Its presentation is declared at 10 mg. This page explains that classification, the group of eight references Melatonin belongs to, the correct reading of its presentation and price, and the documentation that backs each lot. The catalog classifies it as the indolamine N-acetyl-5-methoxytryptamine; it is not a peptide.

Melatonin: an indolamine, not a peptide
The catalog classifies Melatonin as an indolamine, specifically N-acetyl-5-methoxytryptamine. It is a chemical family distinct from the peptides that dominate the rest of the catalog: it is not made of an amino-acid chain, but of a tryptophan-derived structure with an indole group. According to the catalog's verified descriptors, it is also the only indolamine among Péptidos Colombia's references, not only within its own category.
This page does not describe any effect of Melatonin in the body, nor does it present it as a personal-use supplement. The content is limited to chemical classification, presentation, reference price, and verifiable documentary conditions, as with the rest of this catalog's pages.
Melatonin among the catalog's classic hormones and cofactors
The site's curated category groups Melatonin together with Acth 1-39, Alprostadil, EPO, Glutathione, Insulin, Oxytocin Acetate, and Vitamin B12: eight references with long-standing characterization in the technical literature. Of that group, only three are not peptides: Melatonin, Alprostadil, and Vitamin B12.
The other five references in the group are indeed peptides or proteins: the full corticotropin sequence, recombinant erythropoietin, the glutathione tripeptide, insulin, and oxytocin. Keeping that distinction is relevant for anyone organizing inventory by molecular family rather than only by commercial category.
Melatonin's 10 mg presentation: what to state on the quote
Melatonin comes in 10 mg vials. Because it is a mass, its physical form is lyophilized powder in a vial, the same criterion applied to any catalog presentation measured in milligrams.
This presentation's current price is shown in this page's commercial block and must be confirmed there before approving any quote, without assuming it matches another reference in the same curated category.
Melatonin versus Alprostadil and Vitamin B12: three non-peptides, three different families
Melatonin, Alprostadil, and Vitamin B12 are the three non-peptide references in the classic hormones and cofactors category, and all three belong to different chemical families: Melatonin is an indolamine, Alprostadil a synthetic prostaglandin E1 (a lipid derivative), and Vitamin B12 a cobalt compound (cyanocobalamin).
They share a catalog because they are classic, well-characterized molecules in the technical literature, not because of a structural relation among them. This page does not claim any chemical or use equivalence among the three.
Melatonin's COA: laboratory, method, and availability
The certificate of analysis (COA) for each lot of Melatonin is issued by Janoshik Analytical, with purity reported by HPLC and identity confirmed by mass spectrometry (MS). The same documentary procedure applies to the catalog's non-peptide references, not only to peptides. For an indolamine like this one, mass spectrometry confirms the identity of the stated molecule without relying on an amino-acid sequence, which does not exist for this type of compound.
The COA is handled on request and subject to documentary availability. This page does not publish a purity figure of its own for Melatonin, nor does it fill in formula or molecular weight: those data are requested separately and verified against the specific lot's certificate.
Shipping, custody, and quote confirmation
Melatonin is stored according to the documentation applicable to the lot; if it specifies 2–8 °C and protection from light, those conditions are built into custody before shipping. Rates for shipping to Bogotá and nationwide are shown on the site's shipping information, with times confirmed at the time of 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.
The order is always the same: request registered, written quote with Melatonin's presentation, price, and shipping, and payment coordinated at close through the method that confirmation establishes. Keeping the quote, the payment receipt, the shipping confirmation, and the lot's certificate together in one file documents the operation from start to finish.
Frequently asked questions about Melatonin
Is Melatonin a peptide?
No. It is an indolamine (N-acetyl-5-methoxytryptamine). It shares a catalog category with Alprostadil and Vitamin B12, the other two non-peptide references in the group, but does not share a chemical family with them.
What is the price of the 10 mg presentation?
The published reference price is US$124. This is the value in force at the time of this writing; the page's commercial block always shows the current value.
Who issues Melatonin's certificate of analysis?
Janoshik Analytical, per lot, with purity reported by HPLC and identity confirmed by mass spectrometry (MS). It is handled on request and subject to documentary availability.
How is this reference stored?
According to the documentation applicable to the lot. If it specifies 2–8 °C and protection from light, those conditions are built into the custody record before shipping.
How much does shipping cost?
Rates for Bogotá and for the rest of the country are shown on the site's shipping information. Time is confirmed at the time of 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.
How does Melatonin differ from Vitamin B12?
Melatonin is an indolamine (N-acetyl-5-methoxytryptamine); Vitamin B12 is a cobalt compound (cyanocobalamin). Neither is a peptide; they share a catalog category, not a chemical family.
