Information for institutional quotation
VIP: price, documentation and dispatch in Colombia
VIP is offered in the Péptidos Colombia catalog as a peptide reference exclusively for research and laboratory work. The catalog describes it as a 28-amino-acid peptide of the secretin-glucagon family, a structural classification with no relation to the common everyday meaning of the initials. This listing clarifies that naming coincidence, places VIP within the catalog's largest category for immunomodulation and cellular metabolism, describes its presentation, and organizes the purchase documentation: certificate of analysis, storage, shipping, and payment. Identity and purity of the lot are confirmed through the certificate issued by Janoshik Analytical, with HPLC for purity and MS for identity, on request and subject to document availability.

VIP: a 28-amino-acid peptide of the secretin-glucagon family
The catalog describes VIP as a 28-amino-acid peptide of the secretin-glucagon family. This is a structural classification that groups VIP with other peptide hormones of related structure described in the technical literature: it describes only which protein family it belongs to by sequence.
As with the rest of the catalog, this origin classification does not replace analytical verification of the specific lot. The exact identity of each VIP lot — whether it does correspond to this 28-amino-acid sequence — is confirmed with the corresponding certificate of analysis.
Initials that coincide with a common expression: why this listing clarifies the name
This reference's name — VIP — coincides with a commonly used set of initials, with no relation to the peptide's chemical classification. In the Péptidos Colombia catalog, VIP is exclusively the name of this 28-amino-acid peptide; this listing clarifies that to avoid any confusion when searching for or quoting the reference.
When writing a quote request, it is worth pairing the initials VIP with the family classification — secretin-glucagon — or with the 10 mg presentation, so that whoever handles the request immediately identifies that it refers to this catalog reference and not something else.
VIP within a category of 15 distinct references
Immunomodulation, longevity, and cellular metabolism is, with 15 references, one of the catalog's largest groupings. Within that group, VIP shares a research axis with molecules of very different classifications — mitochondrial peptides, coenzymes, bioregulator tripeptides — grouped by the system under study rather than by structure.
That commercial grouping implies no structural relationship between VIP and the rest of the category's references: each keeps its own molecular classification, its own presentation, and its own lot certificate.
KPV and VIP: two distinct classifications in the same category
KPV shares a category with VIP, though structurally they are not alike: KPV is a three-amino-acid tripeptide derived from alpha-MSH, and VIP is a 28-amino-acid peptide of the secretin-glucagon family. Each keeps its own code, its own presentation, and its own current price shown in the commercial block of its page.
For an institution quoting several references from this category in the same order, it is worth listing them as independent line items, each with its full name and code, rather than assuming they share a presentation or classification simply because they belong to the same research axis.
Janoshik COA per lot and storage
The certificate of analysis for VIP is issued by Janoshik Analytical, with HPLC for purity and MS for identity, per lot rather than for the reference in general. For a 28-amino-acid sequence, mass spectrometry is the technique that confirms the material corresponds to the full declared chain and not to a partial fragment from synthesis. Access is on request and subject to document availability; this listing does not publish a purity percentage because that figure corresponds to the certificate for the specific lot shipped.
The storage condition the site declares for the peptide catalog is 2–8 °C, protected from light, applicable when VIP's lot documentation confirms it. Its 10 mg presentation corresponds, as a specification declared in milligrams, to lyophilized powder in a vial.
Quoting, shipping, and payment
Shipping cost varies by destination and is shown on the site's shipping information page. The total quote adds VIP's list price, the number of vials requested, and the shipping cost for the destination. 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.
Payment is arranged after confirming reference, presentation, units, destination, and total in writing. Delivery timing is confirmed during the quote, based on inventory and destination, and the payment receipt should be kept together with that written confirmation to support the purchase in an internal audit.
Frequently asked questions about VIP
Is VIP offered for research?
Yes, exclusively for research and laboratory work. The listing is limited to identification, documentation, storage, and purchase logistics.
What do the initials VIP mean in this catalog?
They are simply the name of a 28-amino-acid peptide of the secretin-glucagon family. It has no relation to the common everyday meaning of the initials.
What is the secretin-glucagon family?
The structural classification the catalog assigns to VIP, grouping it with other peptide hormones of related sequence. It is an origin classification detail, not a description of use.
Where are identity and purity confirmed?
In the certificate of analysis issued by Janoshik Analytical per lot, with HPLC and MS. It is handled on request and subject to document availability.
How much does shipping cost?
Shipping cost varies by destination; see the site's shipping information page for current rates. Payment is arranged after the order is confirmed in writing. 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.
