Buy DSIP

DSIP is a nonapeptide, nine amino acid residues long, catalogued in the literature under the name delta sleep-inducing peptide and the abbreviation that name produced. The Lumo Peptides catalogue carries it in two forms: a vial of powder and a nasal spray kit. This page gives the price of both, with the conversion per milligram where it can be worked out. The material is for laboratory use only; we state no dosage and no method of use.

The two entries

Item	Contents	Price	Per milligram
DSIP vial	10 mg	€ 69,95	€ 7,00
DSIP nasal spray kit	—	€ 74,95	—

The vial holds ten milligrams, which comes to € 7,00 per milligram. That places DSIP in the middle band of the peptide range: above the short sequences of three or four residues, below the long ones that run past thirty.

The kit costs five euros more than the vial. For it we give no conversion, because the item name declares no quantity. A kit holds a vial of powder together with an empty bottle and a pump, and the powder content is not necessarily the same as that of the plain vial. Setting the two side by side per milligram would compare a quantity against an unknown.

What five euros buys

The gap between € 69,95 and € 74,95 is the hardware: the bottle and the pump that turn the powder into something a laboratory can dispense in measured volume. It is not additional peptide, and it is not a different preparation of the substance.

Neither item is a ready solution. Both arrive as freeze-dried powder in a sealed vial, and the kit is prepared in the laboratory in the same way the plain vial is. The difference is only in what the box contains alongside the vial.

Nine residues, and what that means for the price

Chain length is the main thing separating one peptide’s milligram rate from another’s in this catalogue. Solid-phase synthesis attaches one residue at a time, each with its own reagent cycle and its own purification, so the work follows the number of steps rather than the mass at the end. Nine residues is a short run by that measure, and the € 7,00 reflects it.

What that figure does not do is place DSIP on a ladder with the substances sold by the gram, where the vial holds a hundred times as much and the conversion drops accordingly. Those items are not cheaper peptides; they are a different order of quantity, and their numbers belong on a separate axis.

What the label carries

The vial label states three things: the substance, the quantity in milligrams and the lot number. There is no instruction for use on it. On the kit the quantity is missing altogether, which is the direct reason no price per milligram is given for that entry.

The lot number carries the most weight for everything after the sale. It ties the container to its own analysis report, and without it the report would describe some batch of the substance rather than the one you are holding.

Why the page names no dosage

No page on this site states a dose, an amount per administration or a method of use, and that is a decision rather than a gap. The substance is sold as research material, and how research material is used follows from a protocol the laboratory writes itself. A ready-made instruction on the page would move that choice to us, and we have no grounds for making it.

In practice the page therefore reports only what can be measured: what is in the container, how much of it there is, what it costs and which lot it belongs to. Everything else belongs to the protocol, and the protocol is the reader’s own work.

Reconstitution and laboratory supplies

Both entries call for bacteriostatic water, which the catalogue files under laboratory supplies alongside syringes and filters. That group runs to fifteen items and opens at € 2,95, the least expensive part of the range.

No solvent volume appears here, because it follows from the protocol and not from the product. The neurological group that DSIP sits in, together with cerebrolysin, P21 and dihexa, has its own page at Buy Cerebrolysin, and the full price list across the twenty categories is on Buy peptides.

Batch analysis and delivery

Each lot travels with an analysis report giving the lot number, the method applied and the outcome of the purity determination. Its number matches the one on the vial label, so the document can be tied to that container rather than to another batch of the same substance.

Parcels go out from the Netherlands. As the United Kingdom is outside the EU, a British parcel is presented to customs and any import VAT or duty is charged by the carrier to the recipient. Ireland lies within the EU at € 14,95, and import charges do not arise there. Shipping to the United Kingdom costs € 15,95 and is waived above € 200. Every parcel carries a tracking number and the outer packaging is unmarked.

For laboratory and research use only. Not for human or veterinary use.
