Information for institutional quotation
DSIP: price, documentation and dispatch in Colombia
DSIP is offered in two presentations in the Péptidos Colombia catalog: 10 mg vial, from US$79, and 15 mg vial. It is a nonapeptide — nine amino acids — that the technical literature has identified for decades as delta sleep-inducing peptide, a name tied to published studies on delta-wave recordings in laboratory-animal electroencephalograms; this page reproduces that historical name as a matter of scientific nomenclature, not as a use indication for the reader. Within the nootropic peptides and neuromodulators category, DSIP shares space with other references of different origin and structure. What follows is documentary: presentations, price, lot certificate, and purchase conditions for research and laboratory work. The catalog lists it as a nonapeptide known as delta sleep-inducing peptide.
Presentations and visible prices
| Presentation | Code | Reference price |

The price above is the public value per vial. Availability and batch documentation are confirmed before the quotation is accepted.
Where the name comes from, and what it means for this page
The name delta sleep-inducing peptide comes from the scientific literature of the 1970s and 1980s, when it was first isolated and described in association with delta-wave recordings in animal electroencephalograms. It is a piece of historical nomenclature, documented in the reference's structural classification, and this page presents it exactly that way: as the origin of the name, not as a claim about what happens when the material is used.
As a nonapeptide, DSIP is a chain of just nine amino acids, one of the shortest sequences among the nootropic and neuromodulator references in the catalog. That length is a verifiable structural fact, useful for comparing the molecule's size against other references in the same category, without that fact implying anything about the outcome of its use.
Two presentations, two prices, one reference
The catalog lists DSIP in two presentations: 10 mg, with a current listed price from US$79, and 15 mg at a higher price. The institutional request should state which of the two matches the laboratory's need, because each has its own reference code and its own line item in the quote.
The current price for the 10 mg presentation is shown in this page's commercial block and should be confirmed there before approving any quote, without assuming it matches another catalog reference or an earlier inquiry.
Certificate of analysis per lot: Janoshik Analytical, HPLC, and MS
Neither the 10 mg nor the 15 mg presentation carries a published purity figure on this page. The identity and purity of each DSIP lot are confirmed by the certificate of analysis (COA) that Janoshik Analytical issues, using high-performance liquid chromatography (HPLC) for purity and mass spectrometry (MS) for identity.
The COA is handled on request and subject to documentary availability, and corresponds to the specific lot shipped for each presentation. A CAS number, molecular formula, molecular weight, or an exact purity figure do not appear on this page: if the buyer needs them, they should be requested as part of the lot's documentation, not assumed simply because this is a nonapeptide with a well-documented name in the literature.
Storage and handling of a powder vial
Both the 10 mg and 15 mg presentations correspond to powder vials, not a solution measured by volume. The catalog's technical sheet states storage at 2–8 °C, protected from light, for this type of presentation, a condition that should be confirmed against each lot's specific documentation before assigning custody space.
On receipt, it is worth clearly identifying which presentation arrived — 10 or 15 mg — and recording the lot visible on the vial together with the accepted quote. If both presentations were requested in the same order, each should be identified separately in the laboratory's inventory record.
Quote, shipping, and payment for DSIP
Choosing a DSIP presentation in the catalog does not generate an automatic charge. The buyer records the request with the current presentation and price, receives a written commercial confirmation with the total and payment method, and only then coordinates payment. Shipping is calculated separately, with rates for Bogotá and for the rest of the country shown on the site's shipping information, and the time confirmed during the 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.
If the institution needs the COA as an internal approval requirement, it is worth stating so when requesting the quote, specifying which of the two presentations the request refers to. Documentary availability is coordinated within that same commercial process.
DSIP within the experimental neuromodulation category
The nootropic peptides and neuromodulators category brings together, besides DSIP, references such as Semax and Selank — both heptapeptides derived from other proteins — and P21 (P021), a compound derived from ciliary neurotrophic factor. Each reaches that classification by a different structural route: a hormonal fragment, a tuftsin analog, or a peptide associated with delta waves, as the case may be.
Compared with Semax, which derives from a corticotropin fragment, DSIP does not share a structural origin: it is its own nine-amino-acid sequence with its own historical name. The comparison between the two, on this page, stays limited to that difference in origin and chain length, without extending to any claim about what each one does in an organism.
Frequently asked questions about DSIP
What presentations of DSIP are available?
Two: 10 mg vial, from US$79, and 15 mg vial at a higher price. Each has its own code in the catalog.
Why is DSIP known as "delta sleep-inducing peptide"?
It is the historical name it received in the scientific literature of the 1970s and 1980s, tied to studies on delta waves in animal electroencephalograms. This page cites it as a nomenclature fact, not as a use indication.
How is the purity of a DSIP lot verified?
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.
Is DSIP related to Semax or Selank?
All three fall under the experimental neuromodulation category, but DSIP is a nonapeptide with its own name and history, while Semax and Selank are heptapeptides derived from other proteins. They do not share a structural origin.
How much does it cost to ship an order with DSIP?
Rates for Bogotá and for the rest of the country are shown on the site's shipping information, with delivery time confirmed during 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.
