Vitamin B12: price, documentation and dispatch in Colombia
Vitamin B12 is offered at Péptidos Colombia as a laboratory reference for research, within the catalog's classic hormones and cofactors category. Technically it is cyanocobalamin, a cobalt compound, and not a peptide. Its presentation is declared in milliliters — 2 ml — unlike Melatonin and Alprostadil, the other two non-peptide references in the same category, which come in powder. This page explains that classification, the reading of its volume presentation, and the documentation that accompanies each lot. Its verified descriptor is cyanocobalamin, a cobalt compound; it is not a peptide.

Vitamin B12: cyanocobalamin, a cobalt compound
The catalog classifies Vitamin B12 as cyanocobalamin, a compound containing cobalt in its structure. It is not a peptide and is not made of an amino-acid chain; it is a chemical family entirely different from most references in this catalog.
This page does not describe any effect of Vitamin B12 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.
Vitamin B12's 2 ml presentation: how the price is read
Within the curated category that groups Acth 1-39, Alprostadil, EPO, Glutathione, Insulin, Melatonin, Oxytocin Acetate, and Vitamin B12, the latter is the only presentation declared in milliliters. Its current price corresponds to that 2 ml presentation.
As with the rest of this page, the current figure is a reference for institutional quoting and is confirmed in the page's commercial block, without assuming it matches another reference in the category or an earlier inquiry.
Milliliter presentation: the only non-peptide solution in its category
Vitamin B12's specification is 2 ml, a unit of volume rather than mass. For that reason, the physical form that corresponds to it under the catalog's criterion is solution in a vial, unlike Melatonin (10 mg) and Alprostadil (20 ug), which, being declared in mass, correspond to lyophilized powder.
This difference in physical form — solution versus powder — is a vial-handling detail, not an indication of how to employ the material. The catalog does not publish reconstitution or use instructions for any reference; any laboratory procedure remains the responsibility and protocol of the purchasing institution.
Vitamin B12 versus Melatonin: two non-peptides, two physical forms
Vitamin B12 and Melatonin share a catalog category as classic non-peptide references, but come in different physical forms: Vitamin B12 in solution (2 ml) and Melatonin in lyophilized powder (10 mg). Nor do they share a chemical family: cyanocobalamin versus indolamine.
This comparison is limited to the classification and presentation stated by the catalog. Neither page describes an effect in the body or suggests a use other than as a laboratory research reference.
Vitamin B12's per-lot certificate of analysis
The certificate of analysis (COA) for each lot of Vitamin B12 is issued by Janoshik Analytical, with purity reported by HPLC and identity confirmed by mass spectrometry (MS). The documentary procedure is the same as for the catalog's powder presentations, adapted to a solution.
The certificate of analysis is delivered on request and subject to documentary availability, always referring to the shipped lot. This page does not set a purity percentage for Vitamin B12, nor does it fill in formula or molecular weight: when an institutional file needs those fields, they are requested and checked against the lot's document, not against this page.
Solution storage, shipping, and payment
Vitamin B12 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 purchase path does not differ from the rest of the catalog: the request is registered, the quote is confirmed in writing, payment is coordinated through the agreed method, and, if requested, the certificate travels with the material. Marking each document with the same order code is what later allows the operation to be reviewed without tracking down loose messages.
Frequently asked questions about Vitamin B12
Is Vitamin B12 a peptide?
No. It is cyanocobalamin, a cobalt compound. It shares a catalog category with Melatonin and Alprostadil, the other two non-peptide references in the group, but does not share a chemical family with them.
What is the price of the 2 ml presentation?
The published reference price is US$33. This is the value in force at the time of this writing; the page's commercial block always shows the current value.
Who issues Vitamin B12'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 Vitamin B12 differ from Melatonin?
Vitamin B12 is a cobalt compound (cyanocobalamin) presented in a 2 ml solution; Melatonin is an indolamine presented as 10 mg of lyophilized powder. Neither is a peptide.
